This is a 7-week, Phase II, multi-centre, randomised, double-blind, placebo-controlled, parallel group design study in male and female subjects with schizophrenia who are stabilised on antipsychotic medication. Subjects will undergo an open-label, single-dose d-amphetamine therapeutic challenge in a hospital setting before being randomised to receive either GSK239512 or placebo for 7 weeks. They will undergo weekly review of safety, tolerability and cognitive performance measures.
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment

This study aims to evaluate the cognitive enhancing effects and tolerability of GSK239512 compared to placebo in patients with mild to moderate Alzheimer's disease
GSK239512 is being developed for the treatment of symptoms of cognitive impairment in many diseases. GSK239512 is a drug that binds to the Histamine 3 receptor (a protein) in the brain (r...
The purpose of this study is to establish the dose-response curve for therapeutic doses of d-amphetamine on tasks of motivation and reward learning in the same participants and to use d-am...
Addiction to amphetamine is characterized by alternating phases of intoxication and short abstinence, followed by recurrent drug-craving episodes which result in distress and relapse. Addi...
Until positive results were found with oral naltrexone, no medication has been effective against amphetamine dependence. The primary aim of this pilot study is to replicate the findings o...

We conducted a meta-regression analysis of all double-blind, randomized, placebo-controlled clinical trials (DBRCTs) reporting effects of drug and placebo on negative symptoms in people with stable sc...
A powerful central nervous system stimulant and sympathomimetic. Amphetamine has multiple mechanisms of action including blocking uptake of adrenergics and dopamine, stimulation of release of monamines, and inhibiting monoamine oxidase. Amphetamine is also a drug of abuse and a psychotomimetic. The l- and the d,l-forms are included here. The l-form has less central nervous system activity but stronger cardiovascular effects. The d-form is DEXTROAMPHETAMINE.
A chronic form of schizophrenia characterized primarily by the presence of persecutory or grandiose delusions, often associated with hallucination.
A sympathomimetic agent with mainly indirect effects on adrenergic receptors. It is used to maintain blood pressure in hypotensive states, for example, following spinal anesthesia. Although the central stimulant effects of mephentermine are much less than those of amphetamine, its use may lead to amphetamine-type dependence.
