Topical bioavailability of triamcinolone acetonide: effect of dose and application frequency.

The application frequency of topical corticosteroids is a recurrently debated topic. Multiple-daily applications are common, although a superior efficacy compared to once-daily application is not unequivocally proven. Only few pharmacokinetic studies investigating application frequency exist.

Low-dose triamcinolone acetonide in the phytocosmetic lichtena reduces inflammation in mild to moderate atopic dermatitis.

Background: Previously, we reported the efficacy of Lichtena--a phytocosmetic cream product--in atopic dermatitis (AD). Later, fraudulent triamcinolone acetonide (TACA) was detected at low doses (16-40 microg/g) in Lichtena. This suggested that TACA may be effective at much lower concentrations than used in commercial products (1,000 microg/g).
