8-[4,4-bis(4-fluorophenyl)butyl]-1-phenyl-1,3,8-triazaspiro[4.5]decan-4-one
Fluspirilene is a long-acting typical antipsychotic from the class of diphenylbutylpiperazines. It primarily acts through antagonistic blockade of dopamine-D2 and serotonin-5-HT2A receptors, which is used for the treatment of schizophrenia and other psychotic disorders. Due to its mechanism of action, extrapyramidal side effects and other typical neuroleptic risks may occur.

Receptor Profile
Der 5-HT2A-Rezeptor ist ein Serotonin-Rezeptor der Klasse Gq-gekoppelter GPCRs. Er ist der primäre molekulare Angriffspunkt klassischer Psychedelika und spielt eine Rolle bei Kognition und Wahrnehmung.
Der D2-Rezeptor ist ein Gi-gekoppelter Dopaminrezeptor mit hoher Dichte im Striatum. Er ist ein wichtiges Ziel für Antipsychotika und moduliert motorische Funktionen sowie Belohnungsverarbeitung.
