Role of Pharmacogenetics on Tramadol Pharmacokinetics: A Population Pharmacokinetic Model

PSPaula Soria-Chacartegui GWGudrun Würthwein PZPablo Zubiaur

Key Points

To investigate how genetic factors influence tramadol pharmacokinetics using a population model.
Developed a population pharmacokinetic model focusing on tramadol.
Included CYP2D6 phenotype as a key variable.
Suggested exploring CYP2B6 and CYP3A4 phenotypes for further insights.
CYP2D6 phenotype effectively described the pharmacokinetic data for tramadol.
Indicated a need for larger sample sizes to assess clinical impacts.
Pointed out the importance of CYP2B6 and CYP3A4 in understanding tramadol pharmacokinetics.

Abstract

A popPK model including CYP2D6 phenotype well described the data. Further research with increased sample size is needed to analyze the clinical impact and effect of CYP2B6 and CYP3A4 phenotype on tramadol pharmacokinetics.
