Moricizine is an antiarrhythmic agent previously marketed as Ethmozine. It was used for prophylaxis and treatment of serious and life-threatening ventricular arrhythmias. In 2007 it was withdrawn and discontinued for commercial reasons. Moricizine can be administered intravenously but was more commonly provided as an oral formulation.

Chlorphenesin carbamate (Maolate, Musil) is a centrally acting muscle relaxant used to treat muscle pain and spasms. Сhlorphenesin acts in the central nervous system (CNS) rather than directly on skeletal muscle. It also has antifungal and some antibacterial properties. The major adverse effects are drowsiness and dizziness.

Tybamate is a minor tranquilizer that is chemically and pharmacologically related to meprobamate. It is useful in treating anxiety and tension associated with psychoneurotic disorders.

HYDROXYPHENAMATE (LISTICA®) is a carbamate tranquilizer indicated for anxiety. It resembles meprobamate in its effect.

EMYLCAMATE (STRIATRAN®), the carbamate ester of the tertiary alcohol methylpentanol, is a tranquilizing and muscle relaxant agent used for the treatment of anxiety and tension.

Styramate is a nonsedative skeletal muscle relaxant drug, developed by the Armour Pharmaceutical Company in 1952. The drug induces relaxation of skeletal musculus by interruption of nerve transmission in the spinal cord and brain stem rather than by exerting a blocking effect at the junction between the motor nerves and the muscles. In mouse studies styramate was found to exert a selective antagonism to hindleg extensor tonic spasm, induced by maximal electroshock, pentylenetetrazol, and strychnine sulfate. In the clinic, the drug was used in patients with neurologic and neuromuscular disorders, secondary muscular spasms. Styramate is marketed in South Africa under tradename Sinaxamol.

Ethinamate was used to treat insomnia (trouble in sleeping) under the brand name VALMID, but then was replaced by other more efficacy medicines. The mechanism of action was not known. However, was studies, which showed that ethinamate inhibits carbonic anhydrases I and did not inhibit II. Nevertheless, even inhibition carbonic anhydrases I is not sufficiently strong to implicate carbonic anhydrases I in the mechanism of action.

MEPHENESIN CARBAMATE, a mephenesin derivative, is a centrally acting muscle relaxant.

Urethane (Ethyl carbamate) is is an ethyl ester of carbamic acid, that has been found in many fermented food products and alcoholic beverages such as cheese, bread, yogurt, wine, whiskey, soya sauce etc. An in vitro study indicated that Urethane has a potential to inhibit the growth of bacteria, plant tissue, and rat carcinoma. Urethane has been used for many years as an antineoplastic agent for medical purposes but this application ended after it was discovered to be carcinogenic in 1943. Urethane can produce long-lasting anesthesia without affecting blood gases or blood pressure, it has been used in acute studies. In earlier studies, Urethane was also used as a co-solvent for water-insoluble analgesic and sedative drugs in Japan. By US FDA regulations, ethyl carbamate has been withdrawn from pharmaceutical use. However, small quantities of ethyl carbamate are also used in laboratories as an anesthetic for animals.
