Grade A
EP is a 38-year-old female patient that comes in for diabetes education and management. She
was diagnosed 12 years ago and states lately she is not able to control her diet although she
continues a 1600 calorie diet with appropriate daily carbohydrate intake (per dietitian
prescription) and walks 40 minutes every day of the week. She states compliance with all
medications. She denies any history of hypoglycemia despite being able to identify signs and
symptoms and describe appropriate treatment strategies.
PMH: T2DM, HTN, obesity, depression, s/p thyroidectomy due to thyroid cancer
FmHx: Noncontributory
SHx: (−) Smoking, alcohol use, past marijuana use while in high school
Medications: Metformin 850 mg tid, glipizide 20 mg bid, lisinopril 20 mg daily, sertraline 100
mg daily, multivitamin daily
Vitals: BP 128/82 mg Hg; P 72 beats/min; BMI 31 m/kg2
Laboratory test results: Na 134 mEq/L, K 5.4 mEq/L, Cl 106 mEq/L, BUN 16 mg/dL, SCr 0.89
mg/dL, glucose 128 mg/dL; A1C 7.8%
Based on EP's profile above, which of the agents would be able to obtain an A1C goal of less
than 7% and would be appropriate in the patient? Please provide an explanation of
appropriateness or lack thereof.
Exenatide - Exenatide (Bydureon) once weekly has been able to demonstrate weight loss and
decrease A1C% by 0.7% to 1.2% in clinical trials; however it is contraindicated for EP due to the
self-reported history of thyroid cancer.
Dapagliflozin - Dapagliflozin (Farxiga) is contraindicated in this patient due to hyperkalemia
which could be made worse by this drug. The package insert does not indicate a specific
potassium concentration cut off to no longer use this medication; however, there are better
choices in this patient.
Sitagliptin - Sitagliptin (Januvia) is able to obtain an A1C goal of less than 7% based on clinical
trials and currently the patient does not have any cautionary objective measures to not use this
medication. DPP-IV inhibitors are weight neutral. DPP-IV inhibitors can be used in patients
taking sulfonylureas; however, it may be recommended to reduce or stop the sulfonylurea dose.
Acarbose - Acarbose (Precose) is not recommended for initial management and is associated
with significant GI side effects. More information would be needed regarding fasting and post
prandial numbers. In addition, adding acarbose would only lower A1c by 0.8% at best and
therefore would not achieve the desired A1C goal of 7%
JR is a 68-year-old African American man with a new diagnosis of T2DM. He was classified as
having prediabetes (at risk for developing diabetes) 5 years before the diagnosis and has a strong
family history of type 2 diabetes. JR's blood pressure was 150/92 mm Hg. His laboratory results
revealed an A1C of 8.1%, normal cholesterol panel, and normal renal/hepatic function were
noted with today's laboratory test results.
Past medical history: Hypertension (diagnosed 4 y ago) Hyperlipidemia (diagnosed 2 y ago)
Pancreatitis (idiopathic) (acute hospitalization 3 y ago)
Family history: Type 2 diabetes
Medication: HCTZ 25 mg daily, simvastatin 10 mg daily
Allergies: SMZ/TMP
Vitals: BP: 150/92 mm Hg P: 78 beats/min RR: 12 rpm Waist Circumference: 46 in Weight: 267
lb Height: 5 ′ 6 ″ BMI: 43.1 kg/m 2
Despite improvements in the past six weeks due to lifestyle changes and exercise, drug therapy is
to be started for JR's diabetes. Which drug therapy would be the best for JR to trial?
Discuss your opinion of JR's lipid management.
Discuss your opinion of JR's blood pressure management.
Metformin is the drug of choice recommended for most patients with diabetes in addition to
lifestyle modifications assuming no contraindications or intolerabilities are present upon
evaluation. Metformin has also shown to provide positive weight neutral/loss effects in obese
patients. It is crucial to know the renal status of patients commencing metformin therapy to limit
the risk of lactic acidosis (JR is without contraindication).
Since his entry A1C is 7.5%, dual therapy is indicated. There are several potential choices. The
second step can be a dipeptidyl peptidase-4 inhibitor, it can be a glucagon-like peptide-1 (GLP-1)
receptor agonist, it can be a TZD, it can be a sulfonylurea agent, it can be a SGLT2 inhibitor, or it
could be basal insulin. Anything next can be tried depending on what suits the circumstance
DPP4 inhibitors are weight neutral bet relatively benign side effect profile. Sitagliptin has been
associated with case reports of pancreatitis, so this specific agent should be avoided. $$$
GLP-1 analog and has data to support an A1C reduction necessary to gain glycemic control and
may assist with weight loss goals for this patient. New information suggests these agents may
provide benefits in those with ASCVD. JR has a past history of pancreatitis and GLP-1 analogs
are not recommended due to this contraindication
TZDs have data to support an A1C reduction necessary to gain glycemic control, but are
associated with weight gain, negative effects on lipids and increased risk of fracture. Until
recently, TZDs have also been linked to increased CV events and use has fallen out of favor
Sulfonylureas provide excellent A1C lowering, but are also associated with weight gain. They
also have the potential to cause hypoglycemia, so patient education is crucial. Because of his
allergies to "sulfa", use would be contraindicated
SGLT2 inhibitors have data to support an A1C reduction necessary to gain glycemic control. In
addition, they are associated with weight loss and blood pressure lowering. New information
demonstrates these agents may be beneficial in those with ASCVD, heart failure and / or CKD.
They are also associated with dyslipidemias as well. Prior to starting therapy, renal function and
electrolytes would have to be assessed. $$$
Based on the ASCVD recommendations (which are now paralleled by the 2015 ADA
recommendations), all patients with type I or II DM ages 40-75 should be on a moderate
intensity statin. If the patients 10 years ASCVD risk is greater than 7.5%, a high intensity statin
can be considered. Since all information needed to perform the estimate is not present, we can
assume JR need at least moderate intensity statin. ACCE/ACE guidelines still resemble those of
ATPIII. Even so, the recommendation is for a statin regardless of LDL-C in diabetics over 40
with at least 1 risk factor of ASCVD.
Options: atorvastatin 10mg, rosuvastatin 10, simvastatin 20-40, pravastatin 40, lovastatin 40,
fluvastatin 40.
An angiotensin-converting enzyme inhibitor and considered to be a drug of choice for renal
protection in patients with diabetes. ACEi and ARBs have demonstrated a reduction in renal
progression to overt proteinuria. African Americans may not see the maximum effect of blood
pressure lowering with ACEi due to a decreased amount of renin. Combination therapy with a
thiazide would be a reasonable add on
A patient with type 1 diabetes reports taking propranolol for hypertension. What concern does
this information present for the provider?
A patient with Type 1 DM is insulin dependent for glucose control and at high risk for
hypoglycemic episodes. Propanolol causes prolonged hypoglycemic episodes. Needs to switch to
ACE or ARB.
A provider teaches a patient who has been diagnosed with hypothyroidism about a new
prescription for levothyroxine. Which statement by the patient indicates a need for further
teaching?
a. "I should not take heartburn medication without consulting my provider first."
b. "I should report insomnia, tremors, and an increased heart rate to my provider."
c. "If I take a multivitamin with iron, I should take it 4 hours after the levothyroxine."
d. "If I take calcium supplements, I may need to decrease my dose of levothyroxine."
D. Calcium may reduce levothyroxine absorption. Further education is needed if the patient feels
she can take half of a prescribed medication.
MC has undiagnosed multiple gastric ulcers. Shortly after consuming a large meal and alcohol he
experiences significant GI distress. He takes an OTC heartburn remedy. Within a minute or two
he develops what he will later describe as "belching, nausea and a bad bloated feeling". Several
of the ulcers began to bleed and he becomes profoundly hypotensive from the blood loss and is
taken to the ED. Endoscopy confirms multiple bleeds; the endoscopist remarks that it appears as
if the lesions had been literally stretched apart causing additional tissue damage. What did the
patient most likely take (i.e. what was the OTC remedy)?
I would accept Alka-Selzer. I contains NaHCO3 (as well as ASA). In the presence of HCL it
Liberates CO2, that can cause gastric distention, belching and nausea. The reaction is fairly swift
allowing little time for dissipation. Tums, its primary ingredient calcium carbonate which when
taken cause a reaction with the stomach acid such as production of carbon dioxide gas which can
cause bloating and the stomach to stretch to tear the ulcers open.
On your way to this examination, you experience the vulnerable feeling that an attack of acute
diarrhea is imminent! If you stop at a drug store, which anti-diarrheal drugs could you buy
without a prescription even though it is chemically related to the strong opioid analgesic
meperidine (but acts only on the peripheral opioid receptor)?
Loperamide
JA has multiple medical problems and is taking several drugs including theophylline, warfarin
and phenytoin. His conditions were well controlled, but recently he started to experience some
GI distress for which of his "well intentioned friends" gave him some medication. He presents to
you with toxic effects of all his other medications and plasma levels of those medications
elevated. What was most likely the medication he took?
Cimetidine
What lifestyle modifications should be recommended? -losing weight if overweight -elevating head of bed while asleep -eating smaller meals -avoid foods/meds that exacerbate gerd -stop smoking -stop drinking alcohol
What medications / foods can contribute to GERD?
-Medications: anticholinergics, barbituates, dopamine, estrogen, opioids, progesterone,
theophylline, nitrates -Foods: cirus fruits/juices, coffee, tomatoes, spicy food, carbonated drinks
Fried/fatty foods, garlic, onions, chocolate
What is the most effective PPI or H2RA within each of these classes? -PPI- bismuth quadruple therapy combined with proton pump inhibitors -H2RA- Famotidine 80mg
Other products such as antacids are also available. What are some of these and what is their place
in therapy? -Reflux symptoms 2 times a week (infrequent) -Effective for immediate relief -Magnesium/Aluminum Hydroxide (Maalox)- can cause constipation -Alginic Acid
Why would antibiotics be used for PUD caused by H Pylori? What is a typical regimen and
duration of therapy? What patient specific factors should be considered and how should
treatment be monitored?
Considerations before regimen choice: -penicillin allergy -previous exposure to macroglide antibiotics
Strongest Reccomendation: -Bismuth Quadruple Therapy 10-14 days
do not drink alcohol w/ metronidazole
-Salvage regimen should be different than first regimen
Who would be a candidate for prophylaxis of NSAID induced ulcer and what agents are
appropriate? What if the patient is on cardio-protective (low dose) aspirin? What if an NSAID
induced ulcer does develop. How should it be treated?
Candidate: -Candidates: Chronic Nsaid Use, Hx ulcers, Zollinger-Ellison
Prevention Treatment- PPI, standard doses (most effective & best tolerated), Misoprostol (better
than H2RA's, No Pregnancy)
What if an NSAID induced ulcer does develop. How should it be treated?
Ulcer Treatment- -PPI (most effective) -H2RA (Famotidone 40mg daily) -Sucralfate (binding paste, requires multiple doses, adverse med reactions, abdominal side
effects)
Who is a candidate for stress ulcer prophylaxis (SUP)? -ICU patients -Trauma, including spinal cord injuries -Mechanical ventilation -Thermal injuries 35% (almost half the body)
Of the agents available to control the complications of diabetes mellitus, cardiovascular drugs,
and particularly ACE inhibitors, have a pre-eminent place. Experimental and epidemiological
data suggest that activation of the renin-angiotensin-aldosterone system plays an important role
in increasing in the micro- and macrovascular complications in patients with diabetes mellitus.
Not only are ACE inhibitors potent antihypertensive agents but there is a growing body of data
indicating that also they have a specific 'organ-protective' effect. For the same degree of blood
pressure control, compared with other antihypertensive agents, ACE inhibitors demonstrate
function and tissue protection of considered organs. ACE inhibitors have been reported to
improve kidney, heart, and to a lesser extent, eye and peripheral nerve function of patients with
diabetes mellitus. These favorable effects are the result of inhibition of both hemodynamic and
tissular effects of angiotensin II.
Finally, there are a growing number of arguments favoring the use of ACE inhibitors very early
in patients with diabetes mellitus.
There is a "compelling" indication in patients with hypertension and DM. These should be the
1st class of antihypertensive medications used in those with DM + HTN
Recommended for the treatment of the patient with CKD (modestly elevated (30-299 mg/24 h)
or higher levels (300 mg/24 h) of urinary albumin excretion), even in those without DM
Delay progression of nephropathy in Type 1 with or without HTN and any degree of albuminuria
Delay progression of nephropathy in Type 2 with or without HTN and microalbuminuriaReduce
development of microalbuminuria (kidney disease) in Type 2 with or without HTN
ARBs are considered a reasonable alternative for those intolerant of ACEI
Cardioprotective dose ASA (IE baby aspirin or clopidrogel as alternative)For SECONDARY
PREVENTION of CV Events- Use in ALL diabetics with CV diseaseFor PRIMARY
PREVENTION of CV EventsUSE in: high CV risk patients (10-yr CV risk 10%) - Typically:
male 50 yo or female 60 yo with 1 additional major risk factor (FH of CVD, HTN, smoker,
dyslipidemia or albuminuria)MAY consider: intermediate CV risk patrients 10-yr CV risk of 5
10%) - younger patients with 1 or more risk factors, older patients with no risk factorsNOT
recommended: low CV risk patients - men 50 yo or women 60 yo without major CV risk
factors or 10-yr CV risk 5%Note - Many authorities consider DM to be an ASCVD risk
equivalentThis is basically everyone with DM
What are the goals set by ACE /ACCE and are they written in stone for all patients?
Primary target for glycemic control is HbA1C
Individualize HbA1C goal - based on...Duration of DMAge/life expectancyComorbid conditions
Known CVD or advanced comorbid conditionsHypoglycemic unawareness
Individual patient considerations
Please note when transitioning from oral therapy for type II DM to insulin, metformin is
retained! Secretagogues are discontinued possibly when basal insulin is initiated, but definitely
when prandial (fast/rapid) insulin is to be added
Options to add to basal insulin for prandial coverage...
Fast-acting insulin
DPP-4 inhibitors
Incretin mimetics
Glinides
Alpha-glucosidase inhibitors
Colesevelam
What are the various types of oral and non-insulin medications and what represents a rational
combination of medications?
Combinations should have different mechanism of action
Combinations should avoid overlapping ADRs
Combinations should ideally be selected based on need for better basal vs post-prandial control
Selection should account for patient specific concerns (eg. weight, CVD risk, etc)
What antidiabetic medications have compelling indications:
for those with underlying ASCVD or at high risk for CVD
for those with CKD
for those with a compelling need to avoid hypoglycemia
for those where weight is an important consideration (ie which are associated with weight loss,
gain or are weight neutral)
What are the various insulins and describe the pharmacokinetics (onset, peak, duration)and how
are they used (eg basal, basal-bolus, split-mixed, sliding scale (..Ask if you don't understand)).
Basal-bolus (long acting basal + rapid/fast acting bolus) provides the greatest flexibility and
control of all regimens
Sliding Scale Should NOT be used
Difficult to do in home setting, requires education and understanding of patient and caregiver
Allows patient to become hyperglycemic, better to schedule dosing and prevent rises in BG
Requires frequent blood glucose monitoring, $$$ and compliance issues
Can be used as monotherapy or as add-on therapy for T2DM .. Presenting A1C of 9 + symptoms
or failure to achieve goal A1C on adequate trial of 2-3 agents at maximally tolerated doses
Often starting with a long acting insulin
When glycemic goals aren't reached despite basal insulin (Good FBG and pre-prandial BG, but
elevated HbA1C), Consider prandial therapy with fast-acting insulin. Begin fast-acting insulin
before largest meal.Variation exists between ADA and ACCE in their recommendations
If HbA1C still elevated, add fast-acting to another mealSulfonylurea can continue up until the
point where prandial (rapid) insulin is addedMetformin can / should continue !!
What agents are used to treat hypothyroid disease? What makes the medications different and
what do the guidelines recommend for use
Recommendation 22.1: Patients with hypothyroidism should be treated with Levothyroxine
monotherapy. Grade Aother forms of thyroid replacement may be associated with necessary cost,
lack of therapeutic rationale, increase adverse effects and allergenicity (animal based products)
Starting therapyNormal adult dose: 1.6 mcg/kg/day (~100-125 mcg/day) based on IBW
(LBW)Titration by 25-50 mcg every 4-6 weeks until TSH normalizesEXCEPTIONS include
elderly, chronically ill patients or history of cardiovascular disease . Initially 12.5-25 mcg/day,
then titrate to maintenance dose until TSH normalizesExpect higher requirements during
pregnancyThyroid hormone demandIncreases in TBGDestruction of T4 by placental deiodinases
How is treatment monitored and how should results be interpreted as far as therapy changes (the
relationship between TSH and T3-4)
Monitoring should be every 6-8 weeks after starting or dose/product change. If TSH is not in
target range (0.5-2.5 mIU/L) alter dose in 10% to 20% increments. ..
levothyroxine has a T 1/2 of 6-10 days (and NTI .. see below). How does this relate to the fact
that after initiating or changing a does or changing a product (IE brand to generic, generic to
brand or one generic brand to another), TSH should be checked in about 6 weeks?
Why are thyroid replacement drugs considered to have a narrow therapeutic index ( NTI )and
what does that mean clinically?
The therapeutic index (TI) is the range of doses at which a medication is effective without
unacceptable adverse events. Drugs with a narrow TI (NTIs) have a narrow window between
their effective doses and those at which they produce adverse toxic effects. Oral Bioavailability:
(erratic) 40-80%brand vs generic Highly protein bound (99%)Half-lifeEuthyroid = 6-7
daysHypothyroid = 9-10 daysSteady State: @ 6 weeks or 4-5 t1/2 's ... this is the bases for
monitoring @ six weeks from start or changes!
Consider changes such as brand to generic, different generics manufactures, different
pharmacies, etcAny such change will require repeat lab monitoring @ ~ 6 weeks to confirm the
same clinical response
What are some drug-drug, drug-food interactions associated with thyroid replacement
drug binding interactions, di-valent cations, amiodarone, certain antibiotics
RECOMMENDATION 13 Methimazole should be used in virtually every patient who chooses
antithyroid drug therapy for GD, except during the first trimester of pregnancy when
propylthiouracil is preferred, in the treatment of thyroid storm (inhibition of peripheral
conversion), and in patients with minor reactions to methimazole who refuse radioactive iodine
therapy or surgeryDelayed onset
Beta-blockers role in therapy?
So .. beta blockers are used for Symptomatic relief of hyperthyroidism until more definative
therapy is instituted and thyroid levels retun to normal or near normal..
Reduction of peripheral manifestations
Tachycardia, sweating, severe tremor, nervousness
Inhibition of peripheral conversion of thyroid hormones at higher doses (propranolol ONLY)
Small therapeutic effect in magnitude
thyrotoxicosis
Why does amiodarone pose a unique concern to thyroid disorders
"Amiodarone-normal thyroid autoregulation is lost because of the relatively high iodine content"
.. this fact can lead to a situation where amiodarone can cauase BOTH hyper- and hypo
thyroidism, depending on the patient, through several process
blocking thyroid peroxidase
blocking proteolysis of Tg and thyroid hormone
altering organification, etc
What would you recommend if a patient is taking Nexium and Plavix together?
As we have seen through our discussions, there is a lot of information (including an FDA issued
statement in the package insert) describing the drug interaction and reduced efficacy of
clopidogrel if used with a PPI (primarily omeprazole) (or in patients who are genetically slow
CYP2C19 metabolizers); however there is also evidence based information indicating the
interaction is not as significant as originally thought. Bottom line: Despite pharmacokinetic
evidence that omeprazole interferes with clopidogrel metabolism, COGENT trial found addition
of omeprazole to clopidogrel reduced gastrointestinal events without increasing cardiovascular
events.
Note there is no significant difference in efficacy among the H2RAs when given at equipotent
dosesCimetidine is associated with numerous clinically significant DIs
Dose reduction in renal and hepatic insufficiency and in the elderly
Duration of suppression ranges from 6-10 hours and varies with dose
Note there is no significant difference in efficacy among the PPIs when given at equipotent doses
Food may affect absorption. Given 30-60' before a meal. More flexibility in term of dosing with
newer agents (eg. dexlansoprazole)Delayed onset: 3-4 days for full inhibition
Duration of action up to 24 hours due to covalent, irreversible inhibition of proton pump
Patients with known osteoporosis can remain on PPI therapy. Concern for hip fractures and
osteoporosis should not affect the decision to use PPI long-term except in patients with other risk
factors for hip fracture
Final thoughts on GERD:
◦ Therapy for GERD other than acid suppression, including prokinetic therapy and/or baclofen,
should not be used in GERD patients without diagnostic evaluation.
◦ For patients with partial response to once daily therapy with a PPI, tailored therapy with
adjustment of dose timing and/or twice daily dosing should be considered in patients with night
time symptoms, variable schedules, and/or sleep
◦ In patients with partial response to PPI therapy, increasing the dose to twice daily therapy or
switching to a different PPI may provide additional symptom relief.
◦ Maintenance PPI therapy should be administered for GERD patients who continue to have
symptoms after the PPI is discontinued, and in patients with complications including erosive
esophagitis and Barrett's esophagus
◦ Histamine-receptor antagonists (H2RA) therapy can be used as a maintenance option in patients
without erosive disease if patients experience heartburn relief. Bedtime H2RA therapy can be
added to daytime PPI therapy in selected patients with objective evidence of night-time reflux if
needed, but may be associated with the development of tachyphylaxis after several weeks of
usage
Peptic ulcers (gastric and duodenal) are defects in the GI mucosa that extend through the
muscularis mucosa. Causal relationships associate with H. Pylori infection, NSAIDs and SRMD.
Therapy includes non-pharmacological interventions (similar to GERD) and pharmacological
with acid suppression (antacids, H2RAs, PPIs) and/or mucosal protection (sucralfate, colloidal
bismuth, misoprostol), and if present, H Pylori eradication
Acid suppression - see treatment modalities under GERD (Duration / dosages may be different
based on indication)
Mucosal protectionSucralfate - In acid environment it turns into a viscous, sticky polymer that
binds selectively to ulcers and erosions creating a protective layerEfficacy comparable to
H2RAsChemically, contains Al(OH)3, thus behaves as Aluminum as far as ADRs (eg
constipation), DIs (eg chelation)Bismuth - MOA unclearBismuth coats ulcers and erosions,
creating a protective layer against acid and pepsinIt may stimulate PG and mucus secretionIt
binds bacterial endotoxins and has direct antimicrobial activity against pylori
H Pylori eradication - Because of the critical role of H. Pylori in the pathogenesis of peptic ulcer,
eradication of this infection is a standard care in patients with gastric or duodenal ulcers
All regimens include 2 antibiotics & Acid suppression therapy (PPI or H2RA)May include
Bismuth preparation
Note especially duration and comments sections of the table below!
In patients aged 55 yr or younger with no alarm features, the clinician may consider two
approximately equivalent management options: (i) test and treat for H. pylori and a trial of acid
suppression if eradication is successful but symptoms do not resolve or (ii) an empiric trial of
acid suppression with a proton pump inhibitor (PPI) for 4-8 wk
NSAID induced ulcers
Prevention:
Misoprostol or PPI. H2RAs not recommended for prophylaxis.COX-2 inhibitors are associated
with a significantly lower incidence of gastric and duodenal ulcers when compared to traditional
NSAIDs. However, this beneficial effect is negated when the patient is taking concomitant low
dose aspirin. The usefulness of these agents has also been reduced by their association with
myocardial infarction and other thrombotic CV eventsCOX-2 inhibitors and NSAIDs to be
discussed in more detail later in the semester
Candidate for prophylaxis
Candidate for prophylaxis
History of prior gastrointestinal event
Age over 60 (5x greater risk)
High NSAID dosage
Concurrent use of corticosteroids (4x greater risk)
Concurrent use of anticoagulants, antiplatelets or low dose ASA (12x greater risk)
Treatment: Discontinue NSAID If possibleEradicate H Pylori if (+)H2RAs or PPIsPPIs heal
NSAID-related ulcers more effectively as compared with H2RAs and are therefore the
antisecretory drug of choice for treating NSAID-related ulcers, especially when NSAIDs are
continuedPatients with NSAID-associated ulcers should be treated with a PPI for a minimum of
eight weeksSucralfate is an option for healing only if NSAID will be stopped
Constipation
Approach to treatment should begin with determination of cause(including medications a patient
may be on table 21-1)OpiatesAnticholinergics (eg. tricyclic antidepressant (amitryptiline),
diphenhydramine, benztropine, etc.)NDHP-CCB (eg verapamil)Oral iron preparationsCalcium or

Pharmacological agents for diarrhea:
Opiates and derivatives - Acts on peripheral (eg loperamide (Imodium)) and central (eg
diphenoxylate/atropine (Lomotil)) opioid receptors depending on the agent. Those that act on
central mu receptors are control substances and prescription onlyNoninfectious diarrhea (acute &
chronic)Adverse effects: constipation, fatigue, dizziness

We do not routinely use empiric antibiotics in patients with acute diarrhea.
Infectious diarrhea:

The initial step in the treatment of Clostridium difficile infection (CDI) is cessation of the
inciting antibiotic as soon as possible
Therapy for non-severe difficile infection (CDI) consists of oral metronidazole oral
vancomycinLimitations of metronidazole include dose-dependent peripheral neuropathy and side
effects of nausea and metallic taste.Use of oral vancomycin is appropriate for initial therapy of
non-severe disease in patients who are pregnant, breastfeeding, or intolerant/allergic to
metronidazoleRifaximin— Small case series have suggested that sequential therapy with
vancomycin followed by Rifaximin may be effective for the treatment of recurrent CDI
Traveler's diarrhea - the classic travelers' diarrhea due to enterotoxigenic Escherichia coli
(ETEC) generally produces malaise, anorexia, and abdominal cramps followed by the sudden
onset of watery diarrhea. The illness is generally self-limited with symptoms lasting for
approximately one to five days.
Antibiotics are warranted to treat diarrhea in those who develop severe diarrhea, characterized by
more than four unformed stools daily, fever, or blood, pus, or mucus in the stool. In addition,
some travelers desire antibiotic treatment for milder disease if the illness is a large burden on a
business trip or vacation.For mild to moderate disease, anti-motility drugs(eg. loperamide) may
be used as monotherapyFor sever disease, anti-motility drugs(eg. loperamide) may be used
cautiously as adjunctive therapyuse in combination with simethicone may provide faster relief of
symptoms
For adults, several different antibiotic options are effective for travelers' diarrhea. In general,
fluoroquinolones (eg ciprofloxacin) are the first choice for their efficacy and tolerability.
However, for travelers to Asia, azithromycin is preferable because of increasing resistance to
fluoroquinolones among enteric pathogens in that region. Azithromycin is also the preferred
agent for pregnant women and children. We only use Rifaximin if a fluoroquinolone or
azithromycin is not available or appropriate because its efficacy for invasive disease is unknown
Nausea / Vomiting
When choosing an agent
Focus on individual patient, evaluate risk factors, and rule out other causes.

Please review mechanisms, ADRs and
Promethazine -Block DA2 receptors in the CTZ + have antihistaminic and anticholinergic
effects.ADR's: EPS, sedation, hypotension
Place in therapy: "general purpose antiemetics". not very effective in severe n/v (i.e.
chemotherapy induced n/v (CINV)Example Lorazepam -Benzodiazepines bind to GABA-A
receptors. GABA is the major inhibitory NT in the CNS
benzodiazepines are sedatives, not antiemetic agents
Sedative and anti-anxiety effects → reduce anticipatory N/V associated with chemotherapy
ADRs - CNS - sedation, hallucinations, euphoria; CV - hypotension
CINV - Evaluate emetogenic potential of regimen
Mono therapy for chemotherapy with low and moderate emetogenic risk
Aggressive (combination of agents with different mechanisms) antiemetics for highly
emetogenic regimens and delayed CINV Examples
Dexamethasone + metoclopramide + diphenhydramine + lorazepam Ondansetron +
dexamethasone Ondansetron + metoclopramide Metoclopramide + dexamethasone Ondansetron
+ dexamethasone + prochlorperazine
Ondansetron + dexamethasone + aprepitant
Erectile dysfunction -"The inability to attain or sustain an erection adequate for sexual
stimulation"
Can be the result of age related changes (e.g. diminished testosterone, altered response to NO,
etc), comorbidities (e.g. DM, BPH, depression, etc .. Table 51-1), and medications (e.g. 5-alpha
reductase inhibitors, beta-blockers, TCAs, etc. .. Table 51-2)
Before initiating treatment for ED
a physical examination and thorough medical, social, and medication histories with emphasis on
cardiac disease must be taken to assess for ability to safely perform sexual activity and to assess
for possible drug interactions
Diagnosis should include PE (including a check for signs of hypogonadism), medication review,
Hx, and labs ( HbA1C, PSA, FLP, testosterone)
ED treatment should include:
Non-pharmacological interventions
Reduce fat and cholesterol in diet
Decrease or limit alcohol consumption
Eliminate tobacco use and substance abuse
Weight loss if appropriate
Regular exercise
Co-morbidity (DM, HTN, etc.) management - including (if possible) removal of causal
medications
If a medication is removed, consider that it probably will have to be replaced with a reasonable
alternative
Examples:
SSRIs are a potential cause of ED. A reasonable replacement might be bupropion (assuming no
contraindications)
Dutasteride (for BPH) is a common cause of ED. Tardenafil as a replacement for or in
combination with a 5-alpha reductase might be reasonable (assuming no contraindications)
ED Note:
There are occasions where an offending medication can NOT be discontinued because of a
compelling indication and / or lack of a reasonable alternative (eg Beta-blockers in heart failure
or SIHD).
PDE5Is - Often considered drug of choice when pharmacotherapy is necessary. There is no
convincing evidence that one agent in this class is superior to another. Choice may be based on
patient preference, cost, and formularies
There is no drug effect without some type of sexual stimulation because these drugs do not cause
penile erections; they only provide the ability of the penis to respond to sexual stimulation.
Varying duration of action (most 4-5 h, tadalafil 36h).
Headache and flushing most common ADRs. Serious cardiac events possible
Significant DIs exist
+) nitrates - severe hypotensionIn an emergent situation, a patient who has taken sildenafil may
be given a nitrate after 24 hours; for tadalafil, after 48 hours.
Vardenafil does not have a suggested time interval, but blood pressure and heart rate did not
change when the drug was taken 24 hours before nitrate administration. These suggested
intervals are a direct correlation to half-life and duration of action
Prolonging of QT interval
Serious cardiovascular events have been associated with PDE5 inhibitors; therefore, they should
not be used in patients in whom sexual intercourse is inadvisable because of poor cardiac status.
Testosterone replacement (Low-T)
Testosterone replacement regimens should never be administered to men with normal serum
testosterone levels, or in patients with isolated erectile dysfunction as the only sign of
hypogonadism.
Before initiating any testosterone replacement regimen in patients 40 years and older, patients
should be screened for breast cancer, benign prostatic hyperplasia, and prostate cancer. All are
testosterone-dependent conditions and theoretically could be worsened by exogenous
administration of testosterone
Alprostadil - PgE1 analog administered by intracavernosal injection & intraurethral inserts
Because PGs bypass many steps in the erectile cascade, they are quite effective at producing an
erection, even in cases where PDE5 inhibitors cannot do so.
Most invasive and low patient acceptance. Reserved as second or third line treatment
BPH
BPH increases urethral resistance, resulting in compensatory changes in bladder function.
Obstruction-induced changes in detrusor function, including smooth muscle hypertrophy,
compounded by age-related changes in the functioning of the bladder, lead to urinary frequency,
urgency, and nocturia, the most bothersome BPH-related complaints. Not all patients with LUTS
have BPH and not all men with BPH have LUTS.
BPH diagnosis
Diagnosis includes components such as symptom assessment (AUA score), PE and PSA
PSA is present in small quantities in the serum of men with healthy prostates, but is often
elevated in the presence of prostate cancer or other prostate disorders. PSA is not uniquely an
indicator of prostate cancer, but may also detect prostatitis or BPH. PSA correlates with prostate
size and can be used as a prognostic marker
Non-pharmacologic interventions for BPH
Lifestyle modification - limiting EToH, caffeine, avoid certain medications (Table 52-4)(e.g.
decongestants, androgens, etc) as well as addressing co-morbidities (weight loss, etc)
Watchful waiting is the most conservative approach for patients with mild symptoms or those
with moderate symptoms without bother
◦ Appropriate option for patients with mild symptoms (AUA-SI score ≤ 7), and for many with
moderate to severe symptoms (AUA-SI ≥ 8) if they are not bothered
◦ Behavior modification includes restricting fluids close to bedtime, minimizing caffeine,
sweetened drinks and alcohol intake, frequent emptying of the bladder during waking hours (to
avoid overflow incontinence and urgency), and avoiding drugs that could exacerbate voiding
symptoms (e.g. antihistamines, decongestants).
◦ At each visit, assess the patient's risk of developing acute urinary retention by evaluating the
patient's prostate size or using PSA as a surrogate marker of prostate enlargement
The level of symptom distress that individual men are able to tolerate is variable
Alpha-blockers
fairly rapid onset (2-4 weeks) with relatively rapid symptom resolution , durable effect (years)
with AUA symptom index (AUASI) improving 30-45%. No effect on prostate size (PSA) or
disease progression.
Relax smooth muscle in bladder neck, urethra & prostate(Blue dots indicate the distribution of
alpha receptors surrounding the bladder and prostate). It is clear why these agents would provide
rapid relief of symptoms
New second generation (alfuzosin) and third generation (tamsulosin and silodosin) agents are
preferred because of uroselectivity, no need for dose titration and limited orthostasis
Alpha-blockers
Older agents also have an indication for hypertension and have more CV ADRs (e.g. orthostasis,
reflex tachycardia, etc).
e.g. terazosin. doxazosin
dose titration should follow the "start low, go slow" paradigm
Most guidelines advocate for the individual management of BPH and hypertension
Note that the ACC / AHA recommends that that for those with the comorbidities of hypertension
and BPH, each of those conditions should be treated independently based on GDMT. For those
with persistent HTN on maximized first line therapies, alpha-blockers with vascular effects may
provide benefit in terms of additional BP lowering
5 alpha reductase inhibitors
Management of moderate to severe BPH in patients with enlarged prostate glands.
Management of patients who desire medical therapy but cannot tolerate alpha-1-adrenergic
antagonists and do not have predominately irritant symptoms or concomitant erectile dysfunction
(Symptoms are non-bothersome, so the delay in onset would not interfere with Qol)
Reduce prostate size (and PSA) and thus outlet obstruction
Reverse / Slow disease progression
Decrease the risk of disease complications
Note: although dutasteride blocks both the Type I and Type II iso-enzymes of 5-alpha reductase
while finasteride only blocks Type II, there is not a clinically significant difference in outcomes
when either is used
Peak effect 6-12 months, effect is only durable as long as drug is continued (prostate will return
to pre-treatment size (or larger) when / if 5ARIs are stoppedFinasteride & Dutasteride reduces,
but does not stop the prostate from producing PSA
If PSA fails to decline by 50% after 6-12 months or an increase of 0.3 ng/L or more above the
baseline nadir level, patient should be evaluated for prostate cancer. May also indicate worsening
condition or non-compliance with 5 a-reductase inhibitors
ADRs
(androgen insufficiency) decreased libido, impotence & ejaculatory disorder, breast tenderness &
enlargement
PDE5Is (tadalafil)
Treatment of the signs and symptoms of benign prostatic hyperplasia +/- ED
Relaxes smooth muscle of urethra, prostate and bladder neck
Tadalafil may be prescribed alone, or along with an α1-adrenergic antagonist and/or 5α-reductase
inhibitor. Although other phosphodiesterase type 5 inhibitors share the same mechanism of
action as tadalafil and can improve the AUA Symptom Score, tadalafil (which is the only PDE5I
approved by the FDA for this indication) is preferred because of its longer plasma half-life,
which is theoretically beneficial in the management of BPH, a chronic disease.
Comparable efficacy to alpha-blockers for LUTS, but does not increase flow rate or reduce PVR
Peak onset 1-4 weeks
$$$
Tadalafil adverse reactions:
◦ Use with alpha-blockers, antihypertensives or substantial amounts of alcohol may lead to
hypotension
◦ headache, dizziness, flushing, back pain, myalgia, and cyanopsia
Precautions
◦ Unstable angina, uncontrolled or high-risk arrhythmias, persistent hypotension, poorly
controlled hypertension, or New York Heart Association Classification IV congestive heart
failure
Contraindication
◦ Current use of nitrates
BPH combination therapy
Alpha-blocker offer immediate relief; 5 alpha-RIs reduce prostate enlargement over time
◦ In patients with an enlarged prostate gland and an elevated PSA ≥1.4 ng/mL, combination drug
therapy with an α1-adrenergic antagonist and a 5α-reductase inhibitor is more beneficial than
single drug therapy.
◦ Rationale
a-blocker offer immediate relief
5a-RIs reduce prostate enlargement
◦ Works better for those with obstructive symptoms
◦ May consider stopping a-blocker after 6-12 months, but should continue in those patients with
severe symptoms as long as they are responding
BPH combination therapy
◦ -blocker and anticholinergic (or β3 agonist)
For men with low post-void residual urine volumes and irritative symptoms (e.g., frequency,
urgency) that persist during treatment with an alpha-adrenergic antagonist, combination
treatment with an anticholinergic agent can be tried
◦ Improved storage voiding parameters and frequency compared with alpha-1-adrenergic
antagonist therapy alone
◦ For patients who poorly tolerate anticholinergic adverse effects, an alternative is Mirabegron
The risk of side effects, increased post-void residual urine volume, decreased maximal urinary
flow rate, or acute urinary retention is low
BPH combination therapy
◦ a-blocker and PDE-5Is
For men with moderate symptoms of BPH and erectile dysfunction, treatment with daily tadalafil
(5 mg/day) alone or in combination with tamsulosin (0.4 mg/day) can be considered
Addition of PDE-5Is to alpha blockers may improve lower urinary tract symptoms
◦ PDE-5i and 5a-RIs
Addition of PDE-5i to 5a-RIs can offset erectile dysfunction commonly seen with 5a-RIs
Red Flag medications in pregnancy - Commonly used / teratogenic
Warfarin, Phenytoin, Valproic Acid, Carbamazepine, Lithium, ACE inhibitors/ARBs,
Thalidomide, Ethanol, statins .. etc
Considerations must be given to not only those who ARE pregnant, but all women of child
bearing years where pregnancy is possible (planned or un-planned)
Note: this is NOT a comprehensive list, but a good representation for exam purposes
Combined Oral Contraception:
choosing a formulation based on fertility goals, patient preference, discussion of risk/benefits,
Hx (to rule out contraindications .. see US MEC attached)
World Health Organization and the Food and Drug Administration recommend using the lowest
dose pill that is effective (as noted below, efficacy can be impacted by several factors .. including
other medications. Thus, the lowest dose available is not always the lowest most effective dose)
Combined Oral Contraceptives
Risks can include, but not limited to cancers, CV events/HTN, VTE, drug interactions
Concomitant use of broad spectrum antibiotics and combination contraceptives may result in
decreased contraceptive efficacy; however this is Category 1 under US MEC
If a typical failure rate of 1% to 3% is a concern for the patient, consider additional or alternative
forms of birth control
Concomitant use of P450 enzyme inducers (rifampin, phenytoin, carbamazepine, phenobarbital)
may result in decreased contraceptive efficacy
If use COC - use higher doses (at least 35 mcg EE) + high progestin, shorten hormone free
interval to 4 days or less
Avoid low progestin - the patch, POP
Consider additional or alternative forms of birth control
Concomitant use of Anti-HIV protease inhibitors can either increase or decrease serum levels of
estrogens and progestins - may need backup method
Drospirenone can cause hyperkalemia, especially if used with other agents that can increase
potassium (ACEIs, heparin, aldosterone antagonists, etc)
Benefits can include favorable effect on bone, menstrual effects, improved acne, improved
PMDD, etc
Managing hormone concerns
Estrogen
Excess - N/V, cervical mucorrhea, hypertension, headache, breast tenderness, edema, melasma,
bloating
Deficiency - Early or mid-cycle breakthrough bleeding, increased spotting, hypomenorrhea,
vasomotor symptoms
Progestin
Excess - breast tenderness, headache, fatigue, changes in mood
Deficiency - Late break through bleeding, hypermenorrhea, dysmenorrhea
Androgen
Excess - increased appetite, weight gain, acne, oily skin, hirsutism, decreased libido, increased
breast size, breast tenderness, increased LDL, decreased HDL
Amenorrhea - rule out other causes. Can increase to more estrogenic formulation or to triphasic
formulation to decrease amenorrhea.Not a concern if patient is happy.
Acne/ oily skin/ hirsutism - Rule out other causes. Switch to less androgenic formulation of
progestin (or decrease progestin content)3rd generation Desogestrel, norgestimate4th generation
drospirenone
Dienogest
Managing hormone concerns
GI- typically resolves in 1-3 months. Decrease estrogen component will help with nausea.
Decrease progestin component to help with bloating and constipation
Bleeding /spotting - Common (30-50%) when first initiated. Often resolves by 3rd or 4th cycle
Other manipulations of estrogen and progestin depend at the point of the cycle bleeding /
spotting occurs
First rule out other causes including medications (eg. Medications that increase metabolism)If
spotting or bleeding before completing active pills (late cycle (days10-21)) - increase progestin
to enhance endometrial support
Monophasic with higher progestin or triphasic with ing progestin
If spotting after withdrawal bleeding (early cycle (days 1-9))- increase estrogen or decrease
progestin in the early pills(triphasic)If mid-cycle spotting/bleeding - increase both
estrogen/progestin midcycle
Headaches - If headaches start or worsen after starting OC, need to rule out other causes (take
BP, ask about headache, any focal neurologic symptoms)If related to OC use and are not serious - Discontinue OC, Lower estrogen dose, Lower progestin, Eliminate pill free interval (only if HA
occur during pill free interval)
Decreased Libido
Ask about depression
If due to decrease in vaginal lubrication, switch to vaginal ring contraception
Increase estrogen
Hypertension - COCs can cause small increases (i.e., 6 to 8 mm Hg) in blood pressure, regardless
of estrogen dosage
Low -dose COCs is acceptable in women younger than 35 years with well-controlled and
frequently monitored hypertension
Discontinuing the COC usually restores blood pressure to pretreatment values within 3 to 6
months
VTE / Thromboembolism
Estrogens - increase hepatic production of factor VII, factor X, and fibrinogen in the coagulation
cascade, therefore increasing the risk of thromboembolic events
Progestins
Newer 3rd and 4th generation progestins - greater effect on procoagulant, anticoagulant, and
fibrinolytic pathways
Increased resistance to the anticoagulant effect of activated protein C by some progestins
Higher levels of sex hormone binding globulin
For women who are at an increased risk of thromboembolism - Consider low-dose oral estrogen
contraceptives containing older progestins or Progestin -only contraceptive See US MEC
Progestin Only oral contraceptives - indicated in Breastfeeding (post-partum phase), older women, women who cannot take estrogen
The failure rate is higher than other progestin-only methods or COCs
Effectiveness is lowered when taken as little as a few hours late
DM I/II/GDM in pregnancy:
DM I / II / GDM
TreatmentADA diet
Insulin - drug of choice
Regular insulin or NPH
Insulin lispro (Humalog)
Insulin aspart (Novolog)◦Insulin requirements will increase beginning around 28 weeks gestation
and continue to increase due to placental hormones
Increasing data on safety of insulin glargine in pregnancy
Oral agents (metformin / glyburide) 2nd line. Reasonable alternative for women who decline to
take, or are unable to comply with, insulin therapy.
HTN in pregnancy:
HTN
when SBP reaches 160 or DBP reaches 110
Continue treatment when multiple hypertensive's were required before pregnancy or when end
organ damage is present
methyldopa / labatolol / nifedipine ER 1st line
Hypothyroidism in pregnancy:
hypothyroidism
◦ Levothyroxine - DOC
◦ Attain normal thyrotropin concentrations
◦ Women who received thyroid replacement prior to pregnancy can expect an increased dosage
requirement of 25-50% during pregnancy
Depression in pregnancy:
depression
Pregnant patients with severe unipolar major depression who were successfully treated with
antidepressants prior to pregnancy should generally receive the same drug during pregnancy. For
patients who have not been treated with antidepressants in the past, we suggest selective
serotonin reuptake inhibitors (SSRIs) as initial treatment, rather than other antidepressants
No psychotropic drugs with labeling approved by the FDA for use during pregnancy and
lactation
1st line - psychotherapy, but not always an option
SSRI's
◦ Avoid paroxetine (D) during first trimester
CV malformations
◦ Fluoxetine (C) citalopram (C) sertraline (C) --Literature is reassuring, best data for use during
pregnancy
◦ Risk of PPHTN after 20 weeks gestation with SSRI's
◦ Risk of neonatal withdrawal or adaptation syndrome1
d/c 2 weeks before term
TCA's
◦ Literature is reassuring
◦ Possible withdrawal symptoms
Atypical antidepressants
◦ Limited data
Dyslipidemia in pregnancy:
Dyslipidemia
Women who are on statin therapy and anticipate becoming pregnant should stop statins three
months prior to attempting to conceive.
Maternal consumption of fish and marine omega-3 fatty acid supplement is an active area of
investigation because of potential favorable effects on pregnancy and offspring outcome.
Menopause nonpharmacological interventions:
Goals - Alleviate or reduce symptoms, Improve QOL, Minimize ADRs
Non-pharmacological interventions - avoid vasomotor triggers (hot beverage, spicy food, EToh,
etc), exercise, water based lubricants
Pharmacotherapy menopause
Pharmacotherapy - hormone therapy remains the most effective treatment for vasomotor
symptoms and vulvovaginal atrophy, especially in women with moderate to severe symptoms,
provided there is not CHD, significant CHD risk factors or history of breast cancer
Oral Estrogens
FDA approved for moderate to severe vasomotor symptoms, vulvovaginal atrophy and
prevention of post-menopausal osteoporosis.
Note, oral estrogens should NOT be used for osteoporosis prevention in the absence of
vasomotor symptoms of menopause or for patients with local symptoms ONLY
The HOPE trial demonstrated low dose provided equivalent efficacy relief as standard doses
Oral progestins:
Used in women with an intact uterus to reduce endometrial hyperplasia and endometrial cancer
with estrogen monotherapy.
Must be taken minimum of 12-14 days/month
NOT necessary s/p hysterectomy .. so check surgical history
Length of menopause pharmacological therapy:
Length of therapy - The benefit to risk ratio appears to be best if HT is started close to the time of
menopause. Typically can stop 2-3 years after starting. Longer durations may be associated with
CHD, stroke, VTE, various cancers etc.
Can abruptly stop hormone therapy or can taper. No evidence that tapering of HRT reduces the
recurrence of hot flushes compared with sudden discontinuation1 out of every 4 will need to be
re-initiated due to bothersome vasomotor symptoms
Strong consideration for tapering in those on higher doses of estrogen or long duration.
Tapering options
Dose taper - Progressively decrease dose of estrogen
May require 3-6 months in some women
Do not decrease again until symptoms are tolerable and improve
Day taper
Decrease the number of days per week HRT is taken
Do not decrease again until symptoms are tolerable and improve
Combination of dose and day tapering
Note- progesterone is not tapered, only the estrogen component is. Progesterone is stopped at the
end of the taper when completely stopping HRT
Vulvovaginal complications during menopause
can range from vaginal dryness to atrophy , dyspareunia (painful coitus) and lower urinary tract
symptoms (urge incontinence / OAB)
Local or systemic estrogen therapy for symptom relief
Estrogen can help to restore thickness, elasticity, and lubrication
Estrogen can help reduce the risk of recurrent urinary tract infections
In the absence of vasomotor symptoms, local/ topical (vaginal) estrogen therapy should be used.
There is minimal systemic absorption (with exceptions) and does not require the concomitant
administration of a progestin
