Description

Ritanserin is a thiazolopyrimidine that is 5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one which is substituted at position 7 by a methyl group and at position 6 by a 2-{4-[bis(4-fluorophenyl)methylidene]piperidin-1-yl}ethyl group. A potent and long-acting seratonin (5-hydroxytryptamine, 5-HT) antagonist of the subtype 5-HT2 (Ki = 0.39 nM), it is used in the treatment of a variety of disorders including anxiety, depression and schizophrenia. It has little sedative action. It has a role as a dopaminergic antagonist, a serotonergic antagonist, an antipsychotic agent, an anxiolytic drug, an antidepressant and an EC 3.4.21.26 (prolyl oligopeptidase) inhibitor. It is an organofluorine compound, a member of piperidines and a thiazolopyrimidine.|Ritanserin has been used in trials studying the treatment of Cocaine-Related Disorders.|A selective and potent serotonin-2 antagonist that is effective in the treatment of a variety of syndromes related to anxiety and depression. The drug also improves the subjective quality of sleep and decreases portal pressure.

Drug Information

A structurally and mechanistically diverse group of drugs that are not tricyclics or monoamine oxidase inhibitors. The most clinically important appear to act selectively on serotonergic systems, especially by inhibiting serotonin reuptake. (See all compounds classified as Antidepressive Agents, Second-Generation.)|Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus. (See all compounds classified as Antipsychotic Agents.)|Agents that alleviate ANXIETY, tension, and ANXIETY DISORDERS, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions. ADRENERGIC BETA-ANTAGONISTS are commonly used in the symptomatic treatment of anxiety but are not included here. (See all compounds classified as Anti-Anxiety Agents.)|Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or SEROTONIN RECEPTOR AGONISTS. (See all compounds classified as Serotonin Antagonists.)

6-(2-(4-(Bis(4-fluorophenyl)methylene)-1-piperidinyl)ethyl)-7-methyl-5H-thiazolo(3,2-a)pyrimidin-5-one
