Mode of Action
Omeprazole is a substituted benzimidazole gastric antisecretory agent and is also known as PPI. It blocks the final step in gastric acid secretion by specific inhibition of H+/K+ ATPase enzyme system present on the secretory surface of the gastric parietal cell. Both basal and stimulated acid are inhibited.
Precaution
Gastric malignancy should be ruled out. Pregnancy, lactation, childn <1 yr. Monitoring Parameters Monitor Mg concentrations prior to initiation and periodically thereafter.
Lactation
Risk Summary
Limited data suggest omeprazole may be present in human milk; there are no clinical data on effects of omeprazole on breastfed infant or on milk production; developmental and health benefits of breastfeeding should be considered along with mother's clinical need for therapy and any potential adverse effects on breastfed infant from treatment or from underlying maternal condition

Pregnancy Category Note
Risk Summary There are no adequate and well-controlled studies with Omeprazole in pregnant women. Available epidemiologic data fail to demonstrate an increased risk of major congenital malformations or other adverse pregnancy outcomes with first trimester omeprazole use. Reproduction studies in rats and rabbits resulted in dose-dependent embryo-lethality at omeprazole doses that were approximately 3.4 to 34 times an oral human dose of 40 mg (based on a body surface area for a 60 kg person). Teratogenicity was not observed in animal reproduction studies with administration of oral esomeprazole (an enantiomer of omeprazole) magnesium in rats and rabbits during organogenesis with...
... Show moreInteraction
Increased risk of hypomagnesaemia w/ diuretics. May increase INR and prothrombin time w/ warfarin. Increased risk of digoxin-induced cardiotoxic effects. May increase plasma concentration benzodiazepines (e.g. diazepam), clarithromycin and methotrexate. Decreased absorption of itraconazole, ketoconazole, posaconazole, dasatinib, iron salts. May prolong elimination of diazepam, cilostazol, phenytoin and ciclosporin. May reduce the antiplatelet effect of clopidogrel.
Potentially Fatal: May decrease plasma concentrations and pharmacological effects of rilpivirine, nelfinavir and atazanavir.
