A 43 year old male is diagnosed with Schizophrenia but he refused to take treatment. Which of the following antipsychotic drug is the treatment of choice for this patient?

Ans. (d) FluphenazineRef : Harrison 19th ed. 12722Fluphenazine can be given as monthly intramuscular depot preparation. Thus it is preferred in non-compliant patients.Important Points Regarding Anti-Psychotic Agents* Fluphenazine (enanthate and decanoate) and haloperidol (decanoate) are long-acting injectable (s.c. or i.m) forms of typical antipsychotics.* Risperidone is the first atypical antipsychotic available in long-acting injectable form.* Most commonly used antipsychotic by intravenous route is haloperidol* Ziprasidone, aripiprazole, asenapine and iloperidone has negligible risk to cause metabalic adverse effects (weight gain, hyperlipidemia and new onset diabetes mellitus)* Asenapine, paliperidone and ziprasidone has greatest potential to prolong QT interval.
