Pathway Description
Disulfiram Action Pathway
Homo sapiens
Drug Action Pathway
Disulfiram is a drug used in the treatment of cocaine addiction and chronic alcoholism. With regards to cocaine addiction, cocaine inhibits dopamine reuptake by blocking dopamine transporter 1 (DAT1). This increases dopamine concentrations in the synapse and dopamine binding to its receptors induces euphoria. Disulfiram inhibits dopamine beta-hydroxylase, which metabolizes dopamine into norepinephrine. This causes more dopamine to accumulate in the axon terminal and more dopamine is released. When used concomitantly with cocaine, this causes an extremely high concentration of dopamine in the synapse that does not increase the euphoric effects of cocaine, but rather induces an unpleasant sensation of anxiety. This serves to discourage the patient from using cocaine while taking disulfiram. Disulfiram can prevent alcohol metabolism by inhibiting acetaldehyde dehydrogenase in mitochondria, which lead to increased level of acetaldehyde, and eventually result in hangover (e.g. flushing, vomiting, headache, etc.) as the main symptoms. Therefore, disulfiram is not suggested to take while patient consuming alcohol.
