| '''Asenapine''' is a new [[5-HT2A receptor|5-HT<sub>2A</sub>-]] and [[dopamine receptor|D2-receptor]] [[antagonist]] under development for the treatment of [[schizophrenia]] and acute mania associated with [[bipolar disorder]] by [[Schering-Plough]] after its [[November 19]], [[2007]] combination with [[Organon International]]. Development of the drug, through [[Phase III]] trials, began while Organon was still a part of [[Akzo Nobel]].<ref name="GEN200706">{{cite news

Over 3000 patients have participated in [[clinical trial]]s of asenapine, and the [[Food and Drug Administration|FDA]] accepted the manufacturer's [[New Drug Application|NDA]] on [[November 26]], [[2007]] for standard review. <ref>{{cite press release

| Asenapine belongs to a class of neuroleptics known as "[[atypical antipsychotics]]", which have, over the last two decades, become increasingly popular alternatives to "[[typical antipsychotics]]", such as [[haloperidol]]. The manufacturers of asanapine refer to it as a "new generation" or "second generation" atypical antipsychotic.
| |
| | |
| Other atypical antipsychotics include [[aripiprazole]], [[olanzapine]], [[quetiapine]], [[risperidone]], and [[ziprasidone]].
