Pharmacology
of Diclofen Gel 10gm
Dilofenac Sodium
is an anti-rheumatic, anti-inflammatory, analgesic, and antipyretic
non-steroidal anti-inflammatory medication (NSAID). It also contains uricosuric
properties. Diclofenac works by inhibiting prostaglandin production, which is a
key factor in the development of inflammation, discomfort, and fever. When
taken with or after a meal, diclofenac is swiftly and thoroughly absorbed from
the gastrointestinal tract. After consumption, peak plasma concentrations are
obtained in an average of 2 hours. It is 99.7% bound to plasma proteins at
therapeutic dosages. Diclofenac is metabolized in the liver and goes through a
first-pass process.
