  • World Health Organization (WHO)Meprobamate, a bis-carbamate ester, was introduced in 1955 for the treatment of anxiety and was subsequently used as a sedative-hypnotic drug. Psychological and physical dependence can occur and abuse has been reported. Meprobamate is controlled under Schedule IV of the 1971 Convention on Psychotropic Substances. (Reference: (UNCPS4) United Nations Convention on Psychotropic Substances (IV), , , 1971)
  • General DescriptionMeprobamate,2-methyl-2-propyltrimethylene dicarbamate, 2-methyl-2-propyl-1,3-propanediol dicarbamate (Equanil, Miltown), is officiallyindicated as an antianxiety agent. It is also a sedative–hypnotic agent. It has several overall pharmacological properties resembling those of benzodiazepines and barbiturates.The mechanism of action underlying anxiolytic effectsis unknown but may involve effects on conductivity inspecific brain areas.It does not appear to act through effectson GABAergic systems.The drug is effective againstabsence seizures and may worsen generalized tonic–clonicseizures.
  • General DescriptionOdorless white crystalline powder. Bitter taste. Solutions in water are neutral or slightly acidic.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity ProfileMeprobamate is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.
  • HazardCentral nervous system depressant, use restricted by law.
  • Fire HazardFlash point data for Meprobamate are not available; however, Meprobamate is probably combustible.
  • Clinical UseMeprobamate is also a centrally acting skeletal musclerelaxant. The agents in this group find use in several conditions,such as strains and sprains that may produce acutemuscle spasm. They have interneuronal blocking propertiesat the level of the spinal cord, which are said to bepartly responsible for skeletal muscle relaxation.Also,the general CNS depressant properties they possess maycontribute to, or be mainly responsible for, the skeletalmuscle relaxant activity.
  • Safety ProfileHuman poison by unspecified routes. Moderately toxic to humans and experimentally by ingestion. Experimental poison by intravenous, intraperitoneal, and subcutaneous routes. An experimental teratogen. Human systemic effects by ingestion: coma, blood pressure decrease, regional or general arteriolar constriction, dyspnea, cyanosis, respiratory depression, nausea or vomiting, and allergic skin dermatitis. Experimental reproductive effects. Mutation data reported. Implicated in aplastic anemia. Used as a tranquilizer. When heated to decomposition it emits toxic fumes of NOx.
  • Purification MethodsCrystallise it from hot water, aqueous EtOH (m 104-105.5o) or xylene (m 104.1-105.3o). It can be an addictive drug. [Beilstein 3 IV 73.]
