Mechanism of Action

Disulfiram inhibits aldehyde dehydrogenase, the oxidative enzyme of acetaldehyde, a metabolite of alcohol. The latter is accumulated in the blood, thus producing unpleasant symptoms of disulfiram-alcohol reaction when a patient has taken small amounts of alcohol. Onset: 12 hrs. Duration: 1-2 wk after last dose. Absorption: Rapidly absorbed from the GIT; peak plasma concentrations after 8-10 hrs (oral). Metabolism: Reduction to diethyldithiocarbamate by the glutathione reductase system in the erythrocytes. Excretion: Urine (as metabolites); exhaled gas (carbon disulphide).
