Caroldi S, De Paris P, Zotti S, Zanella I, Brugnone F: Effects of disulfiram on serum dopamine-beta-hydroxylase and blood carbon disulphide concentrations in alcoholics. J Appl Toxicol. 1994 Mar-Apr;14(2):77-80.
The aim of this study was to investigate the effects of single and repeated disulfiram doses on serum dopamine-beta-hydroxylase activity and blood carbon disulphide concentrations in a group of abstinent alcoholics. The increase in the blood concentration of carbon disulphide was dose dependent after the oral administration of 100-400 mg of disulfiram. Free carbon disulphide peaked at 12 h while the protein-bound fraction increased at least up to 24 h. Both single (100-400 mg p.o.) and repeated (200 mg daily p.o. for ca. 1 month) administrations failed to inhibit the activity of serum dopamine-beta-hydroxylase. The repeated daily administration of 200 mg of disulfiram also had no influence on copper-activated serum dopamine-beta-hydroxylase, which was the same before and after 1-month treatment period. Contrary to the disulfiram group, the activity of the copper-activated enzyme in the serum of abstinent alcoholics declined significantly during the same 30 days. |
