An aqueous cream formulation of diclofenac sodium, exhibiting maximum permeation flux across freshly excised mouse skin was evaluated for anti- inflammatory activity, using carrangeenan-induced paw oedema and cotton pellet-induced granuloma models in rats and found to be as effective as the marketed gel and oral administration at the equivalent dose of 25 mg/kg body weight. Similar plasma concentration profiles were observed for both formulated and marketed gels. Despite the lower bioavailability (about 2.5 times) compared to the oral route, the effective therapeutic levels were sustained over 24 hours following single transdermal application in rats.
