Ethnic differences in psychopharmacological treatment have received much attention in the last two decades. Most of the research efforts conducted so far in the field of ethnopsychopharmacology have focused on comparative responses to neuroleptics and lithium between white and Asian-American patients, and on comparative responses to tricyclic antidepressants among white, African-American and Hispanic patients. In this article we focus on the response to neuroleptic treatment among white, African-American and Hispanic patients suffering from schizophrenia. Our findings suggest that Hispanic patients need lower doses of neuroleptics than white or African-American patients to attain a similar response in the treatment of schizophrenia. Additionally, our study suggests that, if weight is taken to consideration, African-American patients need the same dose of neuroleptics as do white patients in order to attain a similar response in the treatment of schizophrenia. Further studies are suggested to confirm our findings.
