Administration of a combination of isoniazid (INH ), rifampicin (RIF) and pyrazinamid e (PZA) increased plasma ATN in both groups of patients. ATN concentrations (M± SE) at six hours were higher (P <0.05 ) in elderly than in young patients on day one,8.22 ± 1.50 vs 1.89 ± 0.98 μg/mL); day 30, (5.85 ± 0.82 vs 0.87 ± 0.57 μg/mL; and day 90, (4.84 ± 1.24 vs 0.52 ± 0.50μg/mL). Because total amount of ATN excreted was similar in both groups on the three occasions, more ATN was formed in elderly than young patients. In conclusion, there was more oxidative stress in elderly than young patients. It is thereby suggested that Anti-TB drugs induce formation of ROS and elderly patients are at a greater risk of toxicity probably because of poor antioxidant mechanisms展开更多
