Sažetak
The multidrug resistance transporter, P-glycoprotein (P-gp), encoded by polymorphic MDR1 (ABCB1) gene, is involved in efflux transport of several antidepressants and acts as a barrier to different exogenous noxa in the blood-brain barrier. MDR1 gene belongs to the best understood mediators of drug resistance. Different polymorphisms in MDR1 have been found to be connected with P-gp expression and function. The aims of the study were to investigate the potential influence of MDR1 polymorphisms, exon 26 C3435T and exon 21 G2677T/A, on treatment response to paroxetine (20 mg/day) in patients with major depression. To assess and evaluate therapeutic response to paroxetine, all patients were rated weekly using the HAMD-17 scale. Responders were defined as subjects with a decrease in HAMD scale by ≥ 50% at week 6 of treatment. The study population included 127 patients with major depression (diagnosed by Structured Clinical Interview for DSM-IV disorders). Our results indicated that MDR1 variants G2677T and C3435T are not associated with therapeutic response to paroxetine in patients with major depressive disorder. The associations between paroxetine and P-glycoprotein still need to be clarified.
