5-ethyl-5-pentan-2-yl-1,3-diazinane-2,4,6-trione
Pentobarbital is a barbiturate with sedative, hypnotic, and anticonvulsant effects. It acts by enhancing GABA-A receptor-mediated inhibition in the central nervous system. Due to its narrow therapeutic window and high toxicity, there is a significant risk of overdose and dependence. The substance was previously used as a sleeping aid and for anesthesia, but is less commonly used today due to safer alternatives.
