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 Risk Summary Esomeprazole is the S-isomer of omeprazole and limited data suggest that omeprazole may be present in human milk. There are no clinical data on the effects of esomeprazole on the breastfed infant or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Esomeprazole and any potential adverse effects on the breastfed infant from Esomeprazole or from the underlying maternal condition.

Side effect

>10% Headache (2-11%) 1-10% Flatulence (10%),Indigestion (6%),Nausea (6%),Abdominal pain (1-6%),Diarrhea (2-4%),Xerostomia (3-4%),Dizziness (2-3%),Constipation (2-3%),Somnolence (1-2%),Pruritus (1%) <1% Blood and lymphatic system disorders: Agranulocytosis, pancytopenia Blurred vision, GI disorders: Pancreatitis, stomatitis, microscopic colitis Hepatobiliary disorders: Hepatic failure, hepatitis with or without jaundice Anaphylactic reaction/shock GI candidiasis Hypomagnesemia Musculoskeletal disorders: Muscular weakness, myalgia, bone fracture Nervous system disorders: Hepatic encephalopathy, taste disturbance Psychiatric disorders: Aggression, agitation, depression, hallucination Interstitial nephritis Gynecomastia Bronchospasm Skin and subcutaneous tissue disorders: Alopecia, erythema multiforme, hyperhidrosis, photosensitivity, Stevens-Johnson syndrome, toxic epidermal necrolysis (sometimes fatal fatal)

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 clinical data on effects of esomeprazole 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

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.
