Spiroxasone (INNTooltip International Nonproprietary Name, USANTooltip United States Adopted Name) is a synthetic, steroidal antimineralocorticoid of the spirolactone group which was developed as a diuretic and antihypertensive agent but was never marketed.^[1][2] It was synthesized and assayed in 1963.^[1] The drug is 7α-acetylthiospirolactone with the ketone group removed from the C17α spirolactone ring.^[1] Similarly to other spirolactones like spironolactone, spiroxasone also possesses antiandrogen activity.^[3][4]
