Thialbarbital (Intranarcon) is a barbiturate derivative invented in the 1960s. It has sedative effects, and was used primarily for induction in surgical anaesthesia. [1] Thialbarbital is short acting and has less of a tendency to induce respiratory depression than other barbiturate derivatives such as pentobarbital. [2]


Thialbarbital synthesis: Volwiler, Tabern, U.S. Patent 2,153,730 (1939 to Abbott)
