Mechanism of action

Disulfiram irreversibly inhibits aldehyde dehydrogenase (ALDH), the enzyme responsible for metabolizing acetaldehyde, an intermediate in alcohol metabolism. When a patient taking disulfiram consumes alcohol, acetaldehyde accumulates to toxic levels, triggering an unpleasant disulfiram-alcohol reaction characterized by flushing, nausea, vomiting, chest pain, and hypotension. This aversive conditioning is intended to reinforce abstinence in alcohol use disorder treatment.
