Sigmodal (Rectidon) is a barbiturate derivative. It has sedative, hypnotic and anticonvulsant properties, and was used in surgical anaesthesia in the 1950s,[1][2] although it was never widely used compared to better known barbiturates such as thiopental, and has now been replaced by newer drugs with a better safety profile.
