Answers with Verified Solutions | Latest
Updated 2026
Anti-Ulcer drugs help by: -altering gastric pH by decreasing acid
secretion
-protecting the stomach wall lining by
increasing
mucosal protection
-eradicating harmful bacteria Ex: H. Pylori
What are the main pharmacologic -antacids
categories of drugs we used to -H2 receptor antagonists
manage gastric acid secretion and -proton pump inhibitors (PPIs)
the effects: -prostoglandin analogs
-mucosal protectant sulcrafate (Carafate)
What is the first OTC medication -Antacids
tried by patients with dyspepsia? -->these are typically not effective for
persistant
GERD and PUD
What are antacids? How do they -organic salts
work? -neutralize the hydrochloric acid in the
stomach
-raises the gastric pH above 4.0
What are the main side effects of -diarrhea
antacids? -constipation
,What are the different categories -calcium carbonate
of -sodium bicarbonate
antacids? -aluminum based
-magnesium based
-aluminum hydroxide
What is important teaching for -decreasing the stomach pH can cause the
patients taking antacids? decrease absorption of drugs that rely on
acidic
conditions
-if taking enteric coated
medications--reducing
stomach acid can cause the medication to
dissolve
and absorb in the stomach instead of the
intestine
*always separate antacids from other
medications
by 2 hours*
Calcium carbonate antacids: -Tums
-can cause CONSTIPATION
-require adequate fluid intake to dissolve
-can be used in patients needing to take
an antacid
who also could benefit from extra calcium
intake. -
potential for milk "alkali" syndrome,
metabolic
alkalosis
, Sodium Bicarbonate antacids: -Alka Seltzer
-contains aspirin (ASA)
-potential to WORSEN GI distress.
-increased risk
for water retention and fluid overload
-potential to cause hypertension
-Contraindicated in pregnancy, children,
patient
with CVD*
Aluminum based antacids: -Amphogel
-can cause CONSTIPATION
-requires adequate fluid intake to dissolve
-Contraindicated in patients with renal
insufficiency*
Magnesium based antacids: -Milk of magnesia
-suspension mixture is more effective
-can cause DIARRHEA
-Contraindicated in renal insufficiency*
Aluminum hydroxide antacids: -may decrease the absorption of warfarin*.
-can
cause a chelating affect with drugs such as
tetracyclines, warfarin, and
digoxin-potentially
decreasing their absorption &
effectiveness -high
affinity for phosphate-may cause
hypophasphatemia
What can cause heartburn in -hormonal fluctuations
pregnancy? -anatomic changes
