Therefore, the objectives of this study were (1) to describe the ABCB1 rs2032582 and SLCO1B1 rs4149015 genotype distribution in Indonesian MDR-TB patients; (2) to describe the AUC0–24 and Cmax of moxifloxacin in Indonesian MDR-TB patients; and (3) to assess the association between ABCB1 rs2032582 and SLCO1B1 rs4149015 SNPs and moxifloxacin AUC0–24 and Cmax, corrected for the effect of other predictors. Here, ABCB1 is linked to tuberculosis.
