2015-04-23 14:04:55 | BioPortfolio

Summary

This study will examine the physical response to clozapine or chlorpromazine in people with schizophrenia that has not improved with treatment.

Description

This is a longitudinal double-blind 12-week study of the clinical and biochemical response to clozapine or chlorpromazine in a group of treatment-refractory schizophrenic patients.

The study has 4 phases: (1) A recruitment period; (2) a period of discontinuation of psychotropic medication; (3) a drug-washout period; and (4) a 12-week double-blind trial of clozapine or chlorpromazine.

Medical and Biotech [MESH] Definitions

The prototypical phenothiazine antipsychotic drug. Like the other drugs in this class chlorpromazine's antipsychotic actions are thought to be due to long-term adaptation by the brain to blocking DOPAMINE RECEPTORS. Chlorpromazine has several other actions and therapeutic uses, including as an antiemetic and in the treatment of intractable hiccup.

A phenothiazine antipsychotic used in the management of psychoses, including schizophrenia, and in the control of severely disturbed or agitated behavior. It has little antiemetic activity. Thioridazine has a higher incidence of antimuscarinic effects, but a lower incidence of extrapyramidal symptoms, than CHLORPROMAZINE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p618)

An indole derivative effective in schizophrenia and other psychoses and possibly useful in the treatment of the aggressive type of undersocialized conduct disorder. Molindone has much lower affinity for D2 receptors than most antipsychotic agents and has a relatively low affinity for D1 receptors. It has only low to moderate affinity for cholinergic and alpha-adrenergic receptors. Some electrophysiologic data from animals indicate that molindone has certain characteristics that resemble those of CLOZAPINE. (From AMA Drug Evaluations Annual, 1994, p283)

A phenothiazine with pharmacological activity similar to that of both CHLORPROMAZINE and PROMETHAZINE. It has the histamine-antagonist properties of the antihistamines together with CENTRAL NERVOUS SYSTEM effects resembling those of chlorpromazine. (From Martindale, The Extra Pharmacopoeia, 30th ed, p604)

A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.
