We found that patients with genetically higher DAT levels had better treatment outcomes with disulfiram pharmacotherapy of cocaine dependence than those with lower DAT levels.(Am J Addict 2019;28:311-317).
These data describe the behavioral consequence of cocaine tolerance, provide a putative mechanism for its development, and suggest that compounds that disperse DAT complexes may be efficacious treatments for cocaine addiction.
<b>Background:</b> Preclinical and clinical data suggest that a compound which binds potently to and inhibits the dopamine transporter, but with a slower onset and offset rate than cocaine and with less abuse potential and psychomotor stimulant activity, could be a useful adjunct in the treatment of cocaine dependence.
We genotyped the Int8 and 3'UTR variable number of tandem repeats of the dopamine transporter gene (DAT1/SLC6A3), the TaqIA (rs1800497) and TaqIB (rs1079597) SNP polymorphisms within the dopamine receptor D2 gene and the 19-bp insertion/deletion and c.444G>A (rs1108580) polymorphisms of the dopamine β-hydroxylase gene (DBH) in a Spanish sample of 169 patients with cocaine addiction and 169 sex-matched controls.
Several studies have looked for a link between cocaine addiction and the genes of the dopaminergic system: the genes DRD2, COMT, SLC6A3 (coding for the dopamine transporter DAT) and DBH (coding for the dopamine beta hydroxylase) but unfortunately very few well established results.

The successful intervention into alcohol dependence and craving brought about by baclofen in both human and animal studies elucidates glutamatergic mechanisms in alcoholism whereas the role of the dopamine transporter, in conjunction with both the noradrenergic and serotonergic transporters, are implicated in cocaine dependence and craving.
