How does pentobarbital affect the brain?

Pentobarbital works in the central nervous system by binding to gamma-aminobutyric acid (GABA) A subtype receptors. This action induces a change in the chloride transport receptor, leading to an increase in the duration that the chloride channels remain open, hence potentiating GABA effects.
