NAPROXEN AND ESOMEPRAZOLE MAGNESIUM (esomeprazole magnesium)

Cyclooxygenase Inhibitors
Immunology Approved 2020-02-18

This combination medication is indicated for the relief of signs and symptoms of osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis in adults, and juvenile idiopathic arthritis in adolescents (12 years and older weighing at least 38 kg). It is specifically designed for patients at risk of developing naproxen-associated gastric ulcers. By combining naproxen (an NSAID) with esomeprazole magnesium (a proton pump inhibitor), it manages joint pain and inflammation while reducing the risk of stomach complications. It is not recommended for the initial treatment of acute pain because the absorption of naproxen is delayed in this formulation.

How NAPROXEN AND ESOMEPRAZOLE MAGNESIUM Works

This medication consists of an immediate-release esomeprazole magnesium layer surrounding an enteric-coated naproxen core. Esomeprazole is released first in the stomach to decrease acid production by inhibiting the $H^+/K^+$-ATPase (proton pump) in the gastric parietal cells. The enteric coating then prevents the release of naproxen until it reaches the higher pH of the small intestine. Naproxen provides analgesic and anti-inflammatory effects by inhibiting cyclooxygenase-1 and 2 (COX-1 and COX-2), which leads to a reduction in the synthesis of inflammatory prostaglandins.
