Effects of dopamine agonists on Cebus apella monkeys with previous long-term exposure to fluphenazine.

Sixty-one weeks after 48 weeks of treatment with fluphenazine decanoate or placebo, 37 socially living Cebus apella monkeys were evaluated for differences in dopaminergic sensitivity by exposure to 0.75 mg/kg, i.m.

Cognitive effects of milacemide and methylphenidate in healthy young adults.

Cognitive effects of the novel glycine prodrug milacemide (400 mg), the catecholaminergic agonist methylphenidate (20 mg), and placebo were evaluated in 48 healthy young adults. Throughout a 6-h drug treatment day, subjects repeatedly performed tests of target-detection vigilance, immediate and delayed verbal free recall, and Buschke Selective Reminding; total free recall and forced-choice recognition tests were administered at the end of the day. Significant improvement in both vigilance reaction time and Selective Reminding Sum Recall was observed in the methylphenidate group.

Efficacy of benztropine therapy for drooling.

This study assessed the efficacy of synthetic anticholinergic benztropine and incidence of side-effects in 20 developmentally-disabled patients with severe drooling. The double-blind, placebo-controlled, crossover protocol included one-week baseline, two-week placebo and two-week benztropine conditions (mean dose 3.8 mg).

Mianserin pharmacokinetics and behavior in hyperkinetic children.

The present study was conducted to derive pediatric mianserin pharmacokinetic parameters, which were compared to those from healthy young adults, and to obtain preliminary information regarding the utility of mianserin for the management of hyperkinesis in children. The sample consisted of six prepubescent children with hyperkinetic behavior disorders who had not responded, or had developed tolerance to, stimulant medication. Mianserin pharmacokinetics were derived from plasma samples obtained over a 36- to 50-hour period following a single oral dose which ranged from 0.
