Diazepam is a benzodiazepine.
Gama-Aminobutyric acid (GABA) is an inhibitory neurotransmitter, acting on the GABA receptors in the central nervous system (CNS), thus inhibiting the nerve impulses.
It acts on the benzodiazepine receptors in the brain and the spinal cord. Benzodiazepine receptors in the CNS are linked with GABA receptors as a complex.
Diazepam by binding to the benzodiazepine receptors results in activation of the GABA-benzodiazepine receptor complex, resulting in inhibition of nerve impulses, overall depression of brain and spinal cord.
Thus, Diazepam helps to promote muscle relaxation, reduce anxiety, control of convulsions and promote sleep.

Diazepam is administered orally, rectally, and parenterally with the risk of dependence very much influencing the dose and duration of treatment.
Courses of treatment should be short, not normally exceeding 4 weeks, with diazepam being withdrawal gradually.
Elderly and debilitated patients should be given not more than one-half the usual adult dose
