Figure 4From: Randomized pharmacokinetic evaluation of different rifabutin doses in African HIV- infected tuberculosis patients on lopinavir/ritonavir-based antiretroviral therapy Median concentration-time profile of boosted lopinavir administered with two different doses of rifabutin. The median lopinavir (LPV) concentrations for 14 patients administered 2 different concentrations of rifabutin (RBT). Blue line corresponds to a RBT dose of 150Â mg daily and the purple line to 150Â mg tiw. LPV/r corresponds to boosted lopinavir. The bars represent interquartile range (IQR).Back to article page
