What is the weakest antipsychotic?
Of the atypical antipsychotics, risperidone is the weakest in terms of atypicality criteria. Although early clinical studies with risperidone indicated that the incidence of EPS is not greater than that seen with placebo, this may not be the case.
Why is clozapine so effective?
Clozapine’s relatively rapid dissociation from D2 receptors [13] and its antagonistic activity at the 5-HT2A receptors [11] have been put forward as mechanisms responsible for its effectiveness as an antipsychotic, and its actions at multiple receptors account for many of its adverse effects [14].

Which antipsychotic is best for positive symptoms?
Compared with placebo, amisulpride, risperidone, olanzapine, paliperidone, and haloperidol were found to be more effective than other drugs in reducing positive symptoms (n = 117 studies; 31,179 participants; 21 antipsychotic).
Which is the most effective second-generation antipsychotic drug for treating schizophrenia?
