"(Reuters) - Valeant Pharmaceuticals International Inc's experimental drug to treat psoriasis carries a potential risk of suicide that is challenging to assess due to limited data, a preliminary review by the U.S. Food and Drug Administration said"...
Mechanism Of Action
Corticosteroids play a role in cellular signaling, immune function, inflammation, and protein regulation; however, the precise mechanism of action of DIPROLENE Ointment in corticosteroid responsive dermatoses is unknown.
Trials performed with DIPROLENE Ointment, 0.05% indicate that it is in the super-high range of potency as demonstrated in vasoconstrictor trials in healthy subjects when compared with other topical corticosteroids. However, similar blanching scores do not necessarily imply therapeutic equivalence.
No pharmacokinetics trials have been conducted with DIPROLENE Ointment.
The extent of percutaneous absorption of topical corticosteroids is determined by many factors including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings [see DOSAGE AND ADMINISTRATION].
Topical corticosteroids can be absorbed through normal intact skin. Inflammation and/or other disease processes in the skin may increase percutaneous absorption. Occlusive dressings substantially increase the percutaneous absorption of topical corticosteroids [see DOSAGE AND ADMINISTRATION].
Once absorbed through the skin, topical corticosteroids enter pharmacokinetic pathways similar to systemically administered corticosteroids. Corticosteroids are bound to plasma proteins in varying degrees, are metabolized primarily in the liver, and excreted by the kidneys. Some of the topical corticosteroids and their metabolites are also excreted into the bile.
The safety and efficacy of DIPROLENE Ointment for the treatment of corticosteroid-responsive dermatoses, psoriasis and atopic dermatitis, have been evaluated in three randomized active-controlled trials, two in psoriasis and one in atopic dermatitis. A total of 378 subjects, of whom 152 received DIPROLENE Ointment, were included in these trials. These trials evaluated DIPROLENE Ointment applied twice daily, for 14 days. DIPROLENE Ointment was shown to be effective in relieving signs and symptoms of psoriasis and atopic dermatitis.
