General Info

Category:	Gastrointestinal Agents/ Proton Pump Inhibitor
Product information:	Generic name: Esomeprazole 40mg (Fast releasing tablet) Composition: Each film-coated tablet contains: Esomeprazole Magnesium Trihydrate 40mg Therapeutic Category:Gastrointestinal Agents/ Proton Pump Inhibitor Pharmacological Category: Antisecretory Agent Presentation: 15 x 8’s Pregnancy Category: Not recommended (FDA Category Not Assigned) Lactation: Not recommended

MECHANISM OF ACTION:	Esomeprazole is a prodrug and a weak base, which becomes active in the acidic environment of the parietal cell canaliculi in the stomach. Once activated, it inhibits the H⁺/K⁺-ATPase enzyme (the gastric acid pump), leading to a significant reduction in gastric acid secretion – both basal (resting) and stimulated (food-induced) acid output.

Protein Binding: ~97% Metabolism: Extensively metabolized in the liver (CYP2C19 and CYP3A4 pathways) Excretion: Mainly through urine (80%) and feces (rest). Half-life: 1 to 1.5 hours, but effect lasts longer due to irreversible enzyme inhibition.
