Clotizolam (Ro11-1465) is a thienotriazolodiazepine derivative first invented in the 1970s, which in more recent years has been sold as a designer drug. As with other related thienotriazolodiazepines, it produces sedative, anxiolytic, anticonvulsant and muscle relaxant effects,^[1] and also acts as an inhibitor of platelet-activating factor (PAF).^[2]
