Each capsule contains 50mg of Diclofenac Sodium.
One gram of Gel contains 11.5mg of Diclofenac Diethylamine, which is equivalent to 10mg Diclofenac Sodium.
Diclofenac Sodium is a non- steroidal anti-inflammatory (NSAIDs) agent which has analgesic and anti-pyretic properties. It inhibits prostaglandin synthesis by decreasing the activity of the enzyme cyclo-oxygenase, which results in decreased formation of prostaglandin precursors.
Diclofenac Sodium Capsule is completely absorbed from the intestinal tract but undergoes first pass metabolism and peak plasma concentration occurs in about 2 to 4 hours; at therapeutic concentrations it is more than 99% bound to plasma proteins. Diclofenac is almost entirely metabolized in the liver and the terminal plasma half-life is about 1-2 hours, with metabolic excretion mainly via the kidneys and also in the bile.
Diclofenac Gel is absorbed through the skin. In healthy volunteers approximately 6% of the dose applied is absorbed, as determined by urinary excretion of Diclofenac and its hydroxylated metabolites.
Findings in patients confirm that Diclofenac penetrates inflamed areas following local application. After topical administration of the gel to hand and knee joints, Diclofenac can be measured in plasma, synovial tissue and synovial fluid

NSAIDs are contraindicated in patients who have previously shown hypersensitivity reactions (e.g asthma, rhinitis or urticaria) in response to ibuprofen, aspirin or other non-steroidal anti-inflammatory drugs.

– Increase risk of hemorrhages when non-steroidal anti-inflammatory agents are used in conjunction with anticoagulants has been reported.

– Concomitant use of two or more NSAIDs (including aspirin) should be avoided.
– There is an increased risk of GI bleeding when NSAIDs are administered concomitantly with corticosteroids.
– Patients taking NSAIDs and quinolones may have an increased risk of developing convulsions.

previous history of bronchial asthma since NSAIDs have been reported
to cause bronchospasm in such patients.
– Patient on long term treatment should be monitored and patients with severe hepatic, cardiac or renal insufficiency should be kept under close surveillance as the use of NSAIDs may result in deterioration of renal function.
