Clinical ratings and plasma HVA during cocaine abstinence.
Six patients were evaluated over a 21-day period during inpatient recovery from chronic repeated cocaine use. Serial evaluations of Hamilton depression rating, cocaine craving, plasma homovanillic acid (pHVA), and plasma 3-methoxy-4-hydroxyphenylethyleneglycol (pMHPG) concentrations were determined. There was a distinct increase in cocaine craving between 1 and 2 weeks after the last cocaine use. Levels of pHVA also increased at the time of heightened craving. The data provide preliminary evidence to suggest that changes in cocaine craving during abstinence are positively correlated with changes in dopamine turnover.
