目的 :测定氧氟沙星片剂经尿液的排泄率。方法 :对 7名健康男性志愿者单次给氧氟沙星片剂 2 0 0mg ,采用紫外分光光度法测定该药尿液中的浓度 (测定波长为 3 3 1nm)。 结果 :氧氟沙星片剂经尿液的排泄率为82 .77± 2 .65 %。结论 :用该法测定氧氟沙星片剂经尿液的排泄率 ,其方法简便快速 ,结果可靠 Objective: To determine the urine excretion rate of ofloxacin tablets. Methods: Seven healthy male volunteers were given 200 mg of ofloxacin tablets in a single dose. The urine concentration of the drug was measured by UV spectrophotometry (at a wavelength of 333 nm). Results: The urine excretion rate of ofloxacin tablets was 82.77 ± 2.65%. Conclusion: This method for the determination of ofloxacin tablets through the urinary excretion rate, the method is simple and quick, reliable results
