Drugs for Osteoarthritis, Drugs used for Rheumatoid Arthritis, Non-steroidal Anti-inflammatory Drugs (NSAIDs)


Diclofenac Sodium is a potent non-steroidal anti-inflammatory drug (NSAID) with pronounced anti-rheumatic, anti-inflammatory, analgesic and antipyretic properties. It has also some uricosuric effect. Diclofenac exerts its effect by inhibiting prostaglandin biosynthesis which plays a major role in causing inflammation, pain and fever. Diclofenac is rapidly and completely absorbed from the gastro-intestinal tract when taken with or after meal. Peak plasma concentrations are reached within an average of 2 hours after ingestion of it. At therapeutic concentrations, it is 99.7% bound to plasma proteins. Diclofenac is metabolized in the liver and undergoes first-pass metabolism.

Dosage & Administration

  • Adult: 1 tablet daily, taken whole with liquid, preferably at meal times. If necessary, the daily dose can be increased to 150 mg by supplementation with conventional tablets.
  • Children: 1-3 mg of diclofenac/kg body wt. daily in divided doses.
  • Elderly patients: In elderly or debilitated patients, the lowest effective dosage is recommended, although the pharmacokinetics of diclofenac sodium is not impaired to any clinically relevant extent in elderly patients.

Various non-steroidal anti-inflammatory agents are liable to inhibit the activity of diuretics. Concomitant treatment with potassium sparing diuretics may be associated with increased serum potassium levels, making it necessary to monitor these levels. Patients taking Diclofenac and also receiving digoxin, methotrexate, cyclosporine or lithium should be observed for potential development of the specific toxicities of these drugs. Concomitant administration of other systemic non-steroidal anti-inflammatory agents or glucocorticoids may increase the occurrence of side effects e.g. gastrointestinal bleeding.


It is contraindicated in known hypersensitivity to Diclofenac or other non-steroidal anti-inflammatory drugs to patients with active peptic ulcer and to patients in whom aspirin induced asthma, acute rhinitis and urticaria were observed.
