Benzodiazepines are a class of agents that work on the central nervous system, acting selectively on gamma-aminobutyric acid-A (GABA-A) receptors in the brain. GABA is a neurotransmitter that inhibits or reduces the activity of nerve cells (neurons) within the brain. Benzodiazepines open GABA-activated chloride channels, and allow chloride ions to enter the neuron. This makes the neuron negatively charged and resistant to excitation.
