1 Association of CYP2B6 genetic polymorphisms with bupropion and hydroxybupropion exposure: A systematic review and meta-analysis. Bupropion cytochrome P450 family 2 subfamily B member 6 Homo sapiens
2 INTRODUCTION: Bupropion is metabolized to its active metabolite, hydroxybupropion (HB), by the genetically polymorphic cytochrome P450 2B6 (CYP2B6) enzyme. Bupropion cytochrome P450 family 2 subfamily B member 6 Homo sapiens
3 INTRODUCTION: Bupropion is metabolized to its active metabolite, hydroxybupropion (HB), by the genetically polymorphic cytochrome P450 2B6 (CYP2B6) enzyme. Bupropion cytochrome P450 family 2 subfamily B member 6 Homo sapiens
4 OBJECTIVES: A systematic review and meta-analysis was conducted to quantify the association of bupropion and HB exposure with CYP2B6 variant alleles and genotype-defined metabolizer phenotypes. Bupropion cytochrome P450 family 2 subfamily B member 6 Homo sapiens
5 The ratio of means (RoM) between CYP2B6 genotype or genotype-defined phenotype groups for bupropion exposure was calculated for each study and combined in a meta-analysis. Bupropion cytochrome P450 family 2 subfamily B member 6 Homo sapiens
6 The AUCs of HB and the active moiety (bupropion + HB) were significantly reduced in CYP2B6*6 carriers compared to the non-carriers (HB: RoM 0.77, 95% CI 0.71-0.83; active moiety: RoM 0.81, 95% CI 0.75-0.88). Bupropion cytochrome P450 family 2 subfamily B member 6 Homo sapiens
7 The findings of this study suggest opportunities to further study precision dosing strategies for bupropion therapy based on CYP2B6 genotype. Bupropion cytochrome P450 family 2 subfamily B member 6 Homo sapiens
