POSSIBLE ASSOCIATION OF POLYMORPHISM CYP2D6 * 4 WITH FREQUENT HOSPITAL STAY OF PATIENTS WITH SCHIZOPHRENIA
Abstract
The objective of the study was to study the genetic features that affect the metabolic rate of antipsychotics in patients with schizophrenia being frequently (at least once a year) treated in-hospital. The focus of the study was the genetic polymorphism CYP2D6*4 (1846G> A, rs3892097). A significant correlation between the presence of the CYP2D6*4 genetic polymorphism and frequent hospital stay of patients with schizophrenia was found. One of the probable reasons for this correlation may be a poor efficiency of drug therapy due to the slow metabolism of antipsychotics, most of which are the substrates for the CYP2D6 isoenzyme of cytochrome P450.
