Diazepam possesses anxiolytic and sedative properties which may be of value in the symptomatic relief of manifest anxiety and tension states in psychoneurotic patients. It has also an adjunctive value in the relief of certain neurospastic conditions. Peak blood levels after oral administration of Diazepam are reached within one or two hours after single oral dosing. The acute half-life is six to eight hours with a slower decline thereafter, possibly due to tissue storage. However, after repeated doses, blood levels increase significantly over a period of 24-48 hours. In humans, comparable blood levels of Diazepam were obtained in maternal and cord blood indicating placental transfer of the drug.
