用诺氟沙皇对30例淋病患者进行了治疗，并用微生物法测定其尿药浓度。结果表明，治疗效果与尿药浓度成正比，但服药剂量与尿药浓度无相关性。 Thirty patients with gonorrhea were treated with norfloxacin and their urinary drug concentrations were determined by the microbiological method. The results show that the treatment effect is proportional to the concentration of urine, but the dose and urine concentration had no correlation.
