Diazepam
Diazepam ( /daɪˈæzɨpæm/), first marketed as Valium ( /ˈvæliəm/) by Hoffmann-La Roche, is a benzodiazepine drug. Diazepam is also marketed in Australia as Antenex. It is commonly used for treating anxiety, insomnia, seizures including status epilepticus, muscle spasms (such as in cases of tetanus), restless legs syndrome, alcohol withdrawal, benzodiazepine withdrawal and Ménière's disease. It may also be used before certain medical procedures (such as endoscopies) to reduce tension and anxiety, and in some surgical procedures to induce amnesia. It possesses anxiolytic, anticonvulsant, hypnotic, sedative, skeletal muscle relaxant, and amnestic properties. The pharmacological action of diazepam enhances the effect of the neurotransmitter GABA by binding to the benzodiazepine site on the GABAA receptor (via the constituent chlorine atom) leading to central nervous system depression.
