Warnings & Precautions
Patients with an underlying condition such as inflammatory bowel disease or those in whom dehydration should be monitored carefully if Diclofenac Sodium plus Misoprostol is prescribed.
Pharmacology & Mechanism of Action
It is a combination product containing Diclofenac Sodium, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic properties and Misoprostol, a gastrointestinal (GI) mucosal protective prostaglandin E 1 analog. The mechanism of action of Diclofenac Sodium, like other NSAIDs, is not completely understood but may be related to prostaglandin synthetase inhibition. NSAIDs inhibit prostaglandin synthesis. A deficiency of prostaglandins within the gastric and duodenal may lead to diminish bicarbonate and mucosal secretion and may contribute to mucosal damage caused by NSAIDs. Misoprostol can increase bicarbonate and mucous production & prevents gastric and duodenal ulcers.
