Fluspirilene

Fluspirilene (Redeptin, Imap, R6218) is a diphenylbutylpiperidine typical antipsychotic drug, used for the treatment of schizophrenia.[1] It is administered intramuscularly.[2] It was discovered at Janssen Pharmaceutica in 1963.[3] A 2007 systematic review investigated the efficacy of fluspirilene decanoate for people with schizophrenia:

Fluspirilene decanoate compared to oral antipsychotics[4]
Summary
Participant numbers in each comparison were small so power to identify clear difference is limited. Randomized controlled trial data identified no clear differences between the long-acting injection of fluspirilene and oral medication for outcomes that include adverse effects.[4]
