Brand names of disulfiram

  • Antabuse

Disulfiram is used to facilitate the treatment of persistent alcoholism by means of causing a severe susceptibility to alcohol use. Invented in the 1920s, disulfiram works by preventing the treatment of alcohol in our body by means of restraining the actions of acetaldehyde dehydrogenase, thereby resulting in an undesirable effect whenever anyone consumes alcohol. It is important to note that this medication should always be used together with psychotherapy as well as care. Currently, scientists are studying disulfiram as a probable cure for cocaine dependency because this medication puts off breaking down dopamine - a neurotransmitter whose emission is fuelled following use of cocaine. (Neurotransmitters are chemical substances released by the nerves in the brain to communicate with one another). When dopamine is released in excess, it augments nervousness, raises the blood pressure, gives rise to restiveness, and also further horrible symptoms. Findings of numerous studies have stated that disulfiram also has an anti-protozoal action.

How disulfiram works

Disulfiram obstructs the actions of an enzyme produced by the liver and which is responsible for the metabolism of alcohol, resulting in the build-up of a chemical substance called 'acetaldehyde'.

Therefore, although disulfiram does not cure alcoholism, this medication definitely restrains consumption of alcoholic beverages.
