Generic

Naproxen Sodium + Esomeprazole Magnesium

 

Indication

Naproxen & Esomeprazole is indicated for the relief of signs & symptoms of-

• Osteoarthritis
• Rheumatoid arthritis
• Ankylosing spondylitis &
• To decrease the risk of developing gastric ulcers in patients at risk of developing NSAID-associated gastric ulcers.

 

Pharmacology 

It consists of an immediate release esomeprazole magnesium layer and an enteric coated naproxen core. Therefore, esomeprazole is first released in the stomach and then naproxen dissolves in the small intestine.

Naproxen is a non-steroidal anti-inflammatory drug with analgesic and antipyretic properties. Naproxen's mechanism of action is to inhibit prostaglandin synthesis. Esomeprazole is a proton pump inhibitor that specifically acts on the proton pump and inhibits gastric acid secretion by specifically inhibiting ATPase H + / k + in gastric parietal cells. Esomeprazole blocks final acid production. One step, thus reducing stomach acid.

 

Dosage

Carefully consider the potential benefits & risks of this tablet & other treatment options before deciding to use this tablet. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals. If a dose of Esomeprazole lower than a total daily dose of 40 mg is more appropriate, a different treatment should be considered.
