Pimavanserin 99% see COA kanbei

Pimavanserin is a selective inverse agonist of the 5-HT2A receptor with pIC50 and pKd of 8.73 and 9.3, respectively.
Pimavanserin is a member of the class of ureas in which three of the four hydrogens are replaced by 4-fluorobenzyl, 1-methylpiperidin-4-yl, and 4-(isopropyloxy)benzyl groups. An atypical antipsychotic that is used (in the form of its tartrate salt) for treatment of hallucinations and delusions associated with Parkinson's disease. It has a role as an antipsychotic agent, a 5-hydroxytryptamine 2A receptor inverse agonist and a serotonergic antagonist. It is a member of ureas, a member of piperidines, a member of monofluorobenzenes, an aromatic ether and a tertiary amino compound. It is a conjugate base of a pimavanserin(1+).|Pimavanserin (ACP-103), marketed under the trade name Nuplazid, is a drug developed by Acadia Pharmaceuticals which acts as an inverse agonist on the serotonin receptor subtype 5-HT2A, with 40x selectivity over 5-HT2C, and no significant affinity or activity at 5-HT2B or dopamine receptors. As of September 3, 2009, pimavanserin has not met expectations for Phase III clinical trials for the treatment of Parkinson's disease psychosis. It is in Phase II trials for adjunctive treatment of schizophrenia alongside an antipsychotic medication and is expected to improve the effectiveness and side effect profile of antipsychotics. The results of a clinical trial examining the efficacy, tolerability and safety of adjunctive pimavanserin to risperidone and haloperidol were published in November 2012 and the results showed that pimavanserin potentiated the antipsychotic effects of subtherapeutic doses of risperidone and improve the tolerability of haloperidol treatment by reducing the incidence of extrapyramidal symptoms. On September 2, 2014, the United States Food and Drug administration granted Breakthrough Therapy status to Acadia's New Drug Application for pimavanserin.|Pimavanserin is an Atypical Antipsychotic.|Pimavanserin is an atypical antipsychotic used in the treatment of hallucinations and psychosis in patients with Parkinson disease. Use of pimavanserin is associated with a low rate of serum enzyme elevations during therapy, and it has not been linked to instances of clinically apparent acute liver injury.
