Application

Pentobarbital sodium salt has been used as an anesthetic in rats and mice prior to various in vitro studies.

Biochem/physiol Actions

Pentobarbital (PB) is a barbiturate and a ligand of the γ-aminobutyric acid subtype A (GABAA) receptor. It is a sedative anesthetic majorly used in rodent euthanasia. Pentobarbital possesses hypnotic functionality and muscle relaxing properties. It enhances GABAergic activity. Intraperitoneal injection of PB may result in loss of righting reflex (LORR) and heartbeat cessation.
