[Hydrocortisone 17-butyrate (Locoid), a thirty-year ongoing innovative drug].

Since half a century, dermocorticoids represent worthy compounds in dermatological therapy. About thirty years ago, hydrocortisone 17-butyrate was introduced on the Belgian market. This compound combines good efficiency and reduced risk of side effects. Its topical formulations have been enriched over time. The original Locoid lipocream and Locoid Crelo presentations confer remarkable qualities to the product. We report a synopsis of clinical and translational studies devoted to this unique dermocorticoid.
