The Impact of CYP2D6 Polymorphism on Tramadol Pharmacodynamics

CYP2D6 is an enzyme involved in the hepatic metabolism of many clinically important drugs: antiarrhythmics, antidepressants, antipsychotics, β-blockers, and analgesics such as tramadol and codeine. CYP2D6 is highly polymorphic and significant interindividual variability has been observed worldwide. This study aims to investigate the distribution of CYP2D6 polymorphisms among post-cesarean female patients in Erbil city, Iraq. The findings of this study may indicate the presence of CYP2D6 gene variants among the Kurdish female population in Erbil, which could contribute to tramadol analgesic failure or exaggerated adverse effects. This study could also serve as a foundation for further pharmacogenetic research, individualizing treatments and targeting a larger sample size in the future.
