What is a Pentobarbital?

Pentobarbital is a barbiturate derivative used primarily as a sedative, hypnotic, pre-anesthetic agent, and euthanasia drug in veterinary medicine. It acts on the central nervous system by depressing neuronal activity, producing calming and sleep-inducing effects. As a short-acting barbiturate, its effects begin quickly after administration and last for a few hours. While it was historically used to treat insomnia and seizures, its use today is limited due to the risks of dependency and respiratory depression. Safer alternatives are now preferred in human medicine. In veterinary practice, however, it remains widely used, especially for euthanasia. In countries like Japan, pentobarbital is strictly regulated due to its potential for abuse and serious side effects.
