Hydroxydione, as hydroxydione sodium succinate (INN, USAN, BAN; brand names Viadril, Predion, and Presuren),[1][2][3] is a neuroactive steroid which was formerly used as a general anesthetic, but was discontinued due to incidence of thrombophlebitis.[4] It was introduced in 1957,[3] and was the first neuroactive steroid general anesthetic to be introduced for clinical use, an event which was shortly preceded by the observation of the sedative properties of progesterone in mice.[5]
