Chlordiaze poxide

Drug group:

Chlordiazepoxide is a benzodiazepine. Chlordiazepoxide affects chemicals in the brain that may be unbalanced in people with anxiety. Chlordiazepoxide is used to treat anxiety disorders . Chlordiazepoxide may be used short-term to treat anxiety you may have before a surgery .

Mechanism of effect

Benzodiazepines appear to work by affecting neurotransmitters in the brain, chemicals that nerves release in order to communicate with other nearby nerves. One of these neurotransmitters is gamma-aminobutyric acid (GABA), a neurotransmitter that suppresses the activity of nerves. Chlordiazepoxide binds to benzodiazepine (BZD) binding sites on GABA (A) receptor complexes at several sites within the central nervous system.
This results in an increased binding of the inhibitory neurotransmitter GABA to the GABA(A) receptor. BZDs , therefore, enhance GABA-mediated chloride influx through GABA receptor channels, causing membrane hyperpolarization. The net neuro-inhibitory effects result in the observed sedative, hypnotic, anxiolytic, and muscle relaxant properties.
