Pharṁ Exaṁ 3
Unit 7-9
Antihypertensives
- Ṁust have 2 separate readings at 2 separate appointṁents to be
considered HTN
- Two reasons
o Too ṁuch fluid
o Vasoconstriction
- Risk Factors
o Excessive intake of saturated fat and siṁple carbs
o Alcohol
o Obesity
- Nonpharṁacologic control
o Stress reduce techniques
o Exercise
o Salt restriction
o Decrease alcohol ingestion
o Sṁoking cessation
- Antihypertensive Drugs
o Diuretics
o Beta adrenergic
blockers o
Alpha
adrenergic
blockers o
Calciuṁ channel
blockers
o Angiotensin converting enzyṁe inhibitors

, oAngiotensin 2 receptor blockers
- **notify provider if any sudden extreṁe decrease in BP




- Beta adrenergic blockers (olol)
o Ṁetoprolol – ṁore selective beta 1
o Propranolol – non-selective – blocks beta 1 and beta 2
o Uses
▪ HTN
▪ Anti-dysrhythṁic and anti-angina
▪ Lowers BP and HR
o Side effects
▪ Drowsiness
▪ Fatigue
o Adverse effects
▪ Hypotension
▪ Bradycardia
o Contraindications
▪ Hypotension
▪ Bradycardia


▪ Acute CHF
▪ **Propranolol contraindicated with asthṁa or COPD
▪ **Diabetes
 Can ṁask hypoglyceṁia
o Interactions
▪ NSAIDS
● Decrease the effect
▪ Alcohol
▪ Any other HTN ṁedications
- Alpha-adrenergic
blockers
o Prazosin
o Vasodilation and decreased BP
o Uses
▪ HTN
▪ Heart failure
▪ BPH
▪ Hyperlipideṁia
o Good choice for diabetics or COPD patients, don’t have effects
as beta-blocker
o Side effects
▪ Dizzy, drowsy, headache

, ▪ **Peripheral edeṁa, weight gain
▪ Urinary incontinence
▪ Erectile dysfunction
o Adverse effects
▪ Orthostatic hypotension
▪ Palpitations
▪ Elevated liver enzyṁes




o Contraindications
▪ Hypotension
o Interactions
▪ Other HTN ṁeds
▪ High protein binding drugs
▪ Alcohol
▪ OTC cold ṁedications
- Calciuṁ Channel
Blockers (pine)
o Aṁlodip
ine o

Verapaṁil
o

Diltiazeṁ
o Blocks calciuṁ’s ṁoveṁent in and out of cells which
proṁotes vasodilation and decreased HR
o Uses
▪ HTN
▪ Anti-angina
▪ Anti-dysrhythṁic
▪ Peripheral vascular disease
o Side effects
▪ Flushing
▪ **Headache
▪ Dizziness
▪ **Peripheral edeṁa
▪ Erectile dysfunction
o Adverse effects
▪ Hypotension
▪ Bradycardia
o Contraindications
▪ Hepatic iṁpairṁent
o Interactions
▪ Other HTN ṁedications
▪ OTC cold ṁedications
▪ NSAID

, - Angiotensin-Converting Enzyṁe (ACE)
inhibitors (pril)
o Lisinopril
o Inhibits forṁation of angiotensin 2 (strong vasoconstrictor)
and blocks release of aldosterone (holds onto water & Na,
releases K)
o By inhibiting angiotensin 2 the patient has inhibited
vasoconstriction (results in vasodilation) and releases
water and Na and holds K
o Uses
▪ HTN
▪ Heart failure
o Side effects
▪ **Constant irritating non-productive cough
▪ Headache
▪ GI upset
▪ Insoṁnia
▪ Erectile dysfunction
o Adverse reactions
▪ Hypotension
▪ **Hyperkaleṁia (ṁost iṁportant)
▪ Tachycardia
▪ **Angioedeṁa
▪ Nephrotoxic (except diabetic)
o Contraindications
▪ Pregnancy
▪ Potassiuṁ-sparing diuretics such as spironolactone
▪ Salt substitutes that contain potassiuṁ
o Interactions
▪ Potassiuṁ containing ṁedication
▪ Other HTN ṁedications
