Little controlled drug administration data are available to aid in the interpretation of gamma-hydroxybutyric acid (GHB) distribution in conventional and nonconventional fluids and the potential correlation between the pharmacokinetics of GHB and drug effects. Single oral sodium GHB doses of 50 mg/kg were administered to five volunteers. Plasma, oral fluid, urine, and sweat were analyzed for...

Despite gamma-hydroxybutyrate (GHB) therapeutic uses and the increasing concern about its toxicity, few studies have addressed GHB dose-related effects under controlled administration and their relationship with its pharmacokinetics. The study design was double-blind, randomized, crossover, and controlled. As a pilot pharmacology phase I study, increasing doses of GHB were given. Single oral...

This study investigated whether the immediate and long‐term effects of 3,4‐methylenedioxymethamphetamine (MDMA) on monoamines in mouse brain are due to the parent compound and the possible contribution of a major reactive metabolite, 3,4‐dihydroxymethamphetamine (HHMA), to these changes. The acute effect of each compound on rectal temperature was also determined. MDMA given i.p. (30 mg kg −1 ,...

MDMA (3,4-methylenedioxymethamphetamine, ecstasy) is a widely misused psychostimulant drug abused among large segments of the young population. Pharmacologically it displays effects related to amphetamine-type drugs and a set of distinctive effects (closeness to others, facilitation to interpersonal relationship, and empathy) that have been named by some authors "entactogen" properties. MDMA is...

There is evidence that some heavy users of 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) show signs of neurotoxicity (a cognitive dysfunction, a larger incidence of psychopathology). It has been postulated that the catechol intermediates of methylenedioxyamphetamines such as 3,4-dihydroxymethamphetamine (HHMA), a metabolite of MDMA, may play a role in their neurotoxicity by formation of...
