[Clinical trial of fluocortin butylester in a double-blind contralateral comparison versus fluocortolone and hydrocortisone acetate (author's transl)].

Butyl 6alpha-fluoro-11beta-hydroxy-3,20-dioxo-16alpha-methyl-1,4-pregnadien-21-oate (fluocortin butylester, Vaspit) is a recently developed corticosteroid, its distinguishing properties being that it is non-embryotoxic and has practially no systemic effects. In the course of 6 multicentre studies fluocortin butylester was tested in the forms of cream, ointment and fatty ointment in a comparison with corresponding formulations containing fluocortolone (Ultralan) caproate or pivalate, or hydrocortisone acetate. The total study population comprised 1705 patients with various dermal disorders. The results of these double-blind contralateral studies permit the conclusion that the efficacy of the Vaspit preparations ranges between those of fluocortolone and hydrocortisone acetate. Considering the risks involved with local corticosteroid therapy in children the development of a local corticosteroid with the properties of fluocortin butylester must be acknowledged as an advance.
