Renal impairment: No dosage adjustment needed.

Contraindication

Esomeprazole is contraindicated in patients with known hypersensitivity to any component of the formulation or to substituted Benzimidazoles.

Mode of Action

Esomeprazole is a PPI that suppresses gastric acid secretion by inhibiting H+/K+ ATPase in the gastric parietal cell. It is the S-isomer of omeprazole.

Precaution

Paediatric; pregnancy, lactation. Malignancy and hepatic impairment. Increased risk of developing certain infections such as community-acquired pneumonia. For patients with severe liver impairment, a dose of 20 mg should not be exceeded. Lactation: Unknown whether esomeprazole is distributed into breast milk; discontinue drug or do not nurse

Pregnancy Category Note

Pregnancy There are no adequate and well-controlled studies in pregnant women; esomeprazole is the S-isomer of omeprazole; 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) Lactation Esomeprazole is the S-isomer of omeprazole and limited data suggest that omeprazole may be present in human milk; there are no…

Interaction

Increased risk of digoxin-induced cardiotoxic effects. Increased risk of hypomagnesaemia w/ diuretics. May increase INR and prothrombin time w/ warfarin. May increase serum concentration of tacrolimus, saquinavir, methotrexate. May interfere the elimination of drugs metabolised by CYP2C19 (e.g. diazepam). May decrease the bioavailability of ketoconazole, erlotinib and Fe salts. Potentially Fatal: May decrease serum concentration and pharmacological effects of rilpivirine, atazanavir and nelfinavir. May decrease the antiplatelet effects of clopidogrel.
