Diphenylbutylpiperidine



Diphenylbutylpiperidines are a class of typical antipsychotic drugs which were all synthesized, developed, and marketed by Janssen Pharmaceutica.

They include:
 * Clopimozide (R-29,764)
 * Fluspirilene (Redeptin)
 * Penfluridol (Semap, Micefal, Longoperidol)
 * Pimozide (Orap)

A closely related antipsychotic, amperozide, has an additional nitrogen atom in the heterocyclic ring and is classified as a diphenylbutylpiperazine.
