Cimetidine (Tagamet)
examples of H2 receptor Ranitidine (zantac)
antagonists Famotidine (pepcid)
Nizatidine (Axid)
Cimetidine inhibits hepatic drug-metabolizing enzymes,
thereby increasing the levels of many other drugs. Drugs of
Which H2 receptor antagonists
particular concern are warfarin, phenytoin, theophylline, and
is most likely to interact due to
lidocaine, all of which have a narrow margin of safety. If these
CYP450 enzyme system?
drugs are used with cimetidine, their dosages should be
reduced.
effective drugs for treating gastric and duodenal ulcers. These
agents promote ulcer healing by suppressing secretion of
gastric acid.
Tell me about H2 receptor
Antagonists (H2RAs)
Four H2RAs are available: cimetidine, ranitidine, famotidine, and
nizatidine. All four are equally effective. Serious side effects are
uncommon.
Omeprazole
With long-term use, PPIs can lower magnesium levels, perhaps
by reducing intestinal magnesium absorption. The risk for
hypomagnesemia is increased by other drugs that lower
magnesium, especially thiazide and loop diuretics.
which PPI are associated with
vitamin and/or mineral
For long-term PPI therapy, consider measuring magnesium at
deficiencies?
baseline and periodically thereafter.
Decreased absorption of calcium, magnesium, and vitamin B12
have also been associated with long-term PPI use; therefore,
PPIs are contraindicated in individuals with hypocalcemia due to
complications of bone fractures
