The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the product formulation and the integrity of the epidermal barrier.

Once absorbed through the skin, topical corticosteroids are metabolized, primarily in the liver, and are then excreted by the kidneys. Some corticost...

Two double-blind, randomized, vehicle-controlled trials evaluated 532 subjects aged 18 years and older with moderate to severe plaque psoriasis (IGA 3 or 4 and BSA > 3%). Subjects were treated twice daily with IMPOYZ Cream or vehicle cream for 14 days. The primary endpoint was the proportion of subjects who achieved treatment success at Day 15, where treatment success was defined as an IGA score of 0 (clear) or 1 (almost clear) with at least a 2-grade reduction from baseline. The proportion of subjects who achieved treatment success was also assessed at Day 8 Table 1 presents the efficacy resu...
