Composition
Dolwin tablet: Each tablet contains Naproxen USP 500 mg.
Pharmacology
Dolwin (Naproxen) belongs to a group of medicines called Non-Steroidal Anti-inflammatory drugs (NSAIDs), which are used to reduce inflammation and pain in joints and muscles. Naproxen reduces the prostaglandin synthesis by inhibiting the enzyme, cyclo-oxygenase. Thus it produces anti-inflammatory, analgesic and antipyretic actions.
Indication
Naproxen cannot cure arthritis but is used to give relief of some symptoms such as inflammation, swelling, stiffness and joint pain.
• Pain and inflammation in rheumatic disease (Including juvenile idiopathic arthritis)
• Muscle and bone disorders
• Attacks of gout
• Dysmenorrhea
Dosage & administration
In rheumatic disease: 0.5-1 g daily in 1-2 divided doses; child 2-18 years. Juvenile idiopathic arthritis: 5 mg/kg twice daily (max, 1 g daily). Acute musculoskeletal disorders and dysmenorrhea: 500 mg initially, then 250 mg every 6-8 hours as required; max. dose after first day 1.25 g daily. Acute gout: 750 mg initially, then 250 mg every 8 hours until attack has passed or as directed by the physician.

This preparation should not be given to patients who have experienced asthma, urticaria or allergic-type reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactic-like reactions to NSAIDs have been reported in such patients.

Drug interaction

Aspirin: Plasma concentration of Naproxen can be reduced when Aspirin is given concomitantly, this appeared to be due to increased excretion of Naproxen.

Probenecid: It increases the plasma concentration of Naproxen.
