[History of corticotherapy].

Corticosteroids emerged in the late 1940s, at a time when steroid chemistry began to offer new therapeutic approaches. Extractive chemistry (T. Reichstein), chemical synthesis (E.C. Kendall) and clinical investigations (P. Hench) were combined to result in the discovery of cortisone in 1948, leading to a long series of related derivatives. Besides their first applications to treat Addison's disease and rheumatic or inflammatory diseases, corticosteroids could easily correct many metabolic and functional symptoms. Fluoridation of the steroid skeleton allowed the development of more active and better tolerated molecules. Corticosteroids have revolutionized the treatment of allergic diseases or immunity troubles, graft rejection, many dermatological, respiratory, digestive, eye diseases, etc. It is used today in all areas of therapeutic.
