What is Phenprobamate?

Chemical properties

White shiny crystalline powder. Melting point 101-104°C, soluble in ethanol, chloroform, propylene glycol and ethylenediamine, slightly soluble in ether, almost insoluble in water. Odorless, slightly bitter taste, slightly numb.

The Uses of Phenprobamate

Phenprobamate (3-phenylpropylcarbamate) is a centrally acting muscle relaxant with mild sedative and anticonvulsant effects. Muscle relaxants can enhance and prolong the effect of narcotic drugs and enable to obtain same effect with a smaller amount of alcohol or illicit substance.

Definition

ChEBI: Phenprobamate is a member of benzenes.

Safety Profile

Poison by intravenous and intraperitoneal routes. Moderately toxic by ingestion. Used as a tranquilizer and muscle relaxant. When heated to decomposition it emits toxic fumes of NOx. See also CARBAMATES and ESTERS
