The effect of disulfiram on the urinary excretion of catecholamine metabolites in alcoholic males
Abstract
The urinary -excretion of vanillylmandelic acid (VMA), homovanillic acid (HVA) and total metanephrines (TMNs) was studied in a group of White male alcoholic patients under three experimental conditions - onadmission and prior to treatment, after 7 days of administration of a placebo, and after 9 days of administration of disulfiram 400 mg/d. Disulfiram caused a significant decrease in VMA Jevels compared with the pretreatment (P<0,01) and placebo (P<0,05) levels. The output of HVA and TMNs was unchanged. It is suggested that disulf ram may produce false-negative results in cases of suspected phaeochromocytoma if VMA levels only are assayed. TMNs would appear to be the measurement of choice in such a situation.
