Valium

Generic Name(S): Diazepam

Uses

Uses

Valium (diazepam), an anxiolytic (antipanic and antianxiety) medication, belongs to the class of drugs known as benzodiazepines. It is used for its sedative, anxiety-relieving, and muscle-relaxing effects. It acts on gamma-aminobutyric acid (GABA) receptors, causing the release of a neurotransmitter called GABA in the brain.

Valium was released in 1963 as an improved version of Librium. It is more potent than Librium and quickly surpassed Librium in terms of sales. After the success of Valium, other pharmaceutical companies started introducing other benzodiazepine derivatives.

How Does Valium Work?

Valium acts on GABA receptors. It appears to act on areas of the limbic system, thalamus, and hypothalamus, inducing anxiolytic effects. Diazepam increases the inhibitory processes in the cerebral cortex. The anticonvulsant properties of the drug are due to its binding with voltage-dependent sodium channels rather than GABA receptors. The drug produces muscle relaxant effects through inhibition of polysynaptic pathways in the spinal cord.
