Haloperidol blood levels and clinical outcome: a meta-analysis of studies relevant to testing the therapeutic window hypothesis

Abstract: SUMMARY Haloperidol, the most studied antipsychotic drug, is the only one about which reliable statements on the relationship between blood levels and clinical outcome can be made. A systematic overview was undertaken to determine whether there was an optimum blood concentration range for clinical efficacy. Eighteen published studies which provided individual patient data in tables or graphs were reviewed. Clinical benefits tended to decline when the haloperidol blood concentration was increased above 26 ng/ml… Show more

“…According to a systematic review carried out by our group involving trials performed over the past 30 years on the blood levels of this drug, the efficacy of haloperidol was 55% in schizophrenia and schizoaffective disorder; therefore, the failure rate was only 45% 30 . Nevertheless, following the exclusion of patients with blood levels outside the suggested therapeutic window (8-30 ng/ml), efficacy increased to 62%, i.e.…”

“…A range of clozapine and haloperidol doses encompassing previously reported plasma therapeutic ranges of 350–420 ng/mL for clozapine (Mauri et al, 2007) and 4–26 ng/mL for haloperidol (de Oliveira et al, 1996) were used to treat cultured lymphocytes. Stock solutions of clozapine and haloperidol were prepared in methanol.…”
