We evaluated the effects of human immunodeficiency virus (HIV) disease on pharmacokinetics of antituberculosis medications by measuring concentrations of isoniazid and rifampin in blood and of pyrazinamide and ethambutol in urine. Peak concentration and exposure were reduced for rifampin, and rapid acetylators of isoniazid had lower drug levels. HIV and HIV-tuberculosis patients who have diarrhea and cryptosporidial infection exhibit decreased bioavailability of antituberculosis drugs.
我们通过测量血液中异烟肼和利福平的浓度以及尿液中吡嗪酰胺和乙胺丁醇的浓度,评估了人类免疫缺陷病毒(HIV)疾病对抗结核药物药代动力学的影响。利福平的峰值浓度和暴露量降低,而异烟肼的快速乙酰化者药物水平较低。患有腹泻和隐孢子虫感染的HIV患者及HIV合并结核病患者对抗结核药物的生物利用度降低。
