Both halobetasol propionate and clobetasol 17-propionate exerted very marked antiinflammatory, antiproliferative, and vasoconstrictive effects during evaluation in a range of dermatopharmacologic models. Halobetasol propionate was distinctly more potent than clobetasol 17-propionate in the ultraviolet-induced dermatitis inhibition assay in guinea pigs

A poor percutaneous penetration capability for most topical anti-inflammatory drugs is one of the main causes compromising their therapeutic effects on psoriatic skin. Even though curcumin has shown a remarkable efficacy in the treatment of psoriasis, its effective penetration through

Clobetasol 0.05% spray, a topical clobetasol propionate, is a non-greasy formulation that has shown increased clinical efficacy in a head-to-head comparison with foam formulation. Moreover, available data from randomized, controlled, double-blind trials suggests that clobetasol spray is, in fact, slightly

Clobetasol-17-propionate, the most potent of currently available topical steroids as predicted by the vasoconstrictor assay, has just been approved in the United States. In psoriasis, it has proved significantly more effective than class II steroids and as or more effective
O Yélamos et al.

Treatment response for psoriasis is typically evaluated using clinical scores. However, patients can relapse after clinical clearance, suggesting persistent inflammation. Dermoscopy, reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) can non-invasively improve treatment response assessment. To compare the clinical
