[Anti-inflammatory activity of a topical glucocorticoid, fludroxycortide tape in experimental animals (author's transl)].

Fludroxycortide tape is a thin plastic tape which contains a synthetic glucocorticoid, fludroxycortide of 4 microgram/cm2. fludroxycortide tape with a topical application of 1 cm2 inhibited significantly contact hypersensitivities to oxazolone and picryl chloride in the ear skin of mice and PCA caused by IgE-like antibodies in the depilated abdominal skin of rats. Topical application of 1 to 4 cm2 of fludroxycortide tape produced a significant inhibition against histamine-induced vascular permeability, skin edema induced by intradermal injection of carrageenin into the depilated back and ear edema induced by topical application of croton oil in rats. Topical to oxazolone in dose-dependent manner, and had no thymolytic action, while in a dose of 100 microgram/ear, thymus atrophy occurred. Ear edema induced by croton oil was markedly inhibited by topical application of fludroxycortide (0.4 microgram/ear). Thus, fludorxycortide tape has topical anti-inflammatory activity against both allergic and non-allergic inflammation in mice and rats, and the topical anti-inflammatory activity of fludroxycortide appears to be favourably dissociated from its thymolytic action.
