Genetic Testing is Superior Over Endogenous Pharmacometabolomic Markers to Predict Safety of Haloperidol in Patients with Alcohol-induced Psychotic Disorder.

Background: Previous studies have shown that haloperidol biotransformation is mainly metabolized by CYP2D6. The CYP2D6 gene is highly polymorphic, contributing to inter-individual differences in enzymatic activity, and may impact haloperidol biotransformation rates, resulting in variable drug efficacy and safety profiles.

Objective: The study aimed to investigate the correlation of the CYPD6 activity with haloperidol's efficacy and safety rates in patients with alcohol-induced psychotic disorders.
