Galantamine is a competitive acetylcholine esterase inhibitor with a beneficial therapeutic effect in patients with Alzheimer's disease. The metabolism and excretion of orally administered (3)H-labeled galantamine was investigated in rats and dogs at a dose of 2.5 mg base-Eq/kg body weight and in humans at a dose of 4 mg base-Eq. Both poor and extensive(More)
JNJ-37822681 is a novel, highly selective dopamine D₂ receptor antagonist characterized by a rapid dissociation rate from the dopamine D₂ receptor. This profile was hypothesized to confer antipsychotic efficacy and improved tolerability. In this 12-week study, the efficacy and safety of JNJ-37822681 were evaluated in patients with an acute exacerbation of(More)
Absorption, metabolism, and excretion of paliperidone, an atypical antipsychotic, was studied in five healthy male subjects after a single dose of 1 mg of [(14)C]paliperidone oral solution ( approximately 16 microCi/subject). One week after dosing, 88.4 to 93.8% (mean 91.1%) of the administered radioactivity was excreted: 77.1 to 87.1% (mean 79.6%) in urine(More)
Galantamine is a reversible, competitive inhibitor of acetylcholinesterase and an allosteric modulator of nicotinic acetylcholine receptors. It is cleared by renal and hepatic mechanisms, including metabolism by the CYP 450 2D6 and 3A4 isoenzymes. The authors estimated the population pharmacokinetics of galantamine using nonlinear mixed-effects modeling as(More)
Paliperidone extended-release tablet (paliperidone ER) is a centrally active dopamine D(2)- and serotonergic 5-HT(2A)-receptor antagonist that is registered for the treatment of schizophrenia. The controlled rate of release of paliperidone from the ER formulation is designed to have a slower absorption rate, which results in gradual ascending plasma(More)
The single-dose pharmacokinetics of lubeluzole were investigated in 2 single-blind, placebo-controlled, dose-escalation studies in healthy male subjects. In the first study, 6 subjects received an intravenous infusion of 2.5, 5, and 10 mg lubeluzole. In the second study, a 15 mg dose of lubeluzole was administered to 6 subjects, of whom 5 also received 20(More)
OBJECTIVE The metabotropic glutamate receptor subtype 2 (mGlu2 ) possesses both orthosteric and allosteric modulatory sites, are expressed in the frontal cortex and limbic structures, and can affect excitatory synaptic transmission. Therefore, mGlu2 is a potential therapeutic target in the treatment of epilepsy. The present study seeks to evaluate the(More)
The aim of this study was to compare the pharmacokinetics of galantamine in healthy Japanese and Caucasian subjects and assess the safety and tolerability of galantamine in both ethnic groups. Parallel groups of healthy Japanese (n = 13; 6 males and 7 females)and Caucasian (n = 12; 6 males and 6 females) subjects matched for weight and age received single(More)
