Definition

A benzodiazepine derivative with anti-anxiety, sedative, hypnotic and anticonvulsant properties. Diazepam potentiates the inhibitory activities of gamma-aminobutyric acid (GABA) by binding to the GABA receptor, located in the limbic system and the hypothalamus. This increases the frequency of chloride channel opening, allowing the flow of chloride ions into the neuron and ultimately leading to membrane hyperpolarization and a decrease in neuronal excitability.
