 It is a gastric proton pump inhibitor. Omeprazole is a
substituted benzimidazole derivative acting on the final step of
acid production & therefore controls intragastric acidity
irrespective of stimulus. It markedly inhibits basal and
stimulated gastric acid secretion. Thus it is antisecretory drug
which is very effective for rapidly healing peptic ulcers &
erosive oesophagitis & for reducing gastric acid hyper-secretion
in patients with Zollinger-Ellison syndrome.
Working
The drug acts by relaxing blood vessels so that blood passes
through them more easily. This further helps to lower blood
pressure.

ulcer in adults. Most patients heal within four weeks. Some
patients may require an additional four weeks of therapy.
Gastric Ulcer (adults)

active benign gastric ulcer in adults.
PRECAUTIONS
Concomitant Gastric Malignancy
Symptomatic response to therapy with omeprazole does not preclude
the presence of gastric malignancy.
Atrophic Gastritis
Atrophic gastritis has been noted occasionally in gastric corpus
biopsies from patients treated long-term with omeprazole.
CONTRAINDICATIONS
Omeprazole
Prilosid Delayed-Release Capsules are contraindicated in patients
with known hypersensitivity to any component of the formulation.
Clarithromycin
Clarithromycin is contraindicated in patients with a known
hypersensitivity to any macrolide antibiotic.
Concomitant administration of clarithromycin with cisapride,
pimozide, or terfenadine is contraindicated. There have been
post-marketing reports of drug interactions when clarithromycin
and/or erythromycin are co-administered with cisapride, pimozide,
or terfenadine resulting in cardiac arrhythmias (QT prolongation,
ventricular tachycardia, ventricular fibrillation, and torsades de
pointes) most likely due to inhibition of hepatic metabolism of
these drugs by erythromycin and clarithromycin. Fatalities have
been reported. (Please refer to full prescribing information for
clarithromycin before prescribing.)
