2. Pharmacology:
-
Naproxen: NSAID with analgesic and antipyretic properties; inhibits prostaglandin synthesis to reduce pain and inflammation.
-
Esomeprazole: Proton pump inhibitor; suppresses gastric acid secretion by inhibiting Hâē/Kâē ATPase in gastric parietal cells, reducing gastric acidity.
-
The tablet has an immediate-release Esomeprazole layer and an enteric-coated Naproxen core, releasing Esomeprazole first to protect the stomach before Naproxen absorption.
