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 an antidepressant, an anxiolytic drug, an antipsychotic agent, a serotonergic antagonist, a dopaminergic antagonist and an EC 3.4.21.26 (prolyl oligopeptidase) inhibitor. It is a member of piperidines, an organofluorine compound and a thiazolopyrimidine.

Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or SEROTONIN RECEPTOR AGONISTS.
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.
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.
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.
DescriptionRitanserin, also known by its developmental code name R-55667, is a serotonin antagonist medication described as an anxiolytic, antidepressant, antiparkinsonian agent, and antihypertensive agent. It was never marketed for medical use due to safety problems but has been used in scientific research to study the serotonin system.
UsesRitanserin and other 5HT2A/2C receptor antagonists have shown in clinical trial to promote slow-wave sleep in chronic primary insomnia or generalized anxiety disorder (Mayer, 2003).
UsesRitanserin has been used in behavioral testing and as a serotonin 2A receptor (5-HT2A)-receptor antagonist.
