Chlorproguanil and chlorcycloguanil concentrations in human plasma and urine were measured using a high performance liquid chromatographic method. The detection limit in plasma and urine was 5 ng/ml for chlorproguanil and 10 ng/ml for chlorcycloguanil. The elimination half-life of chlorproguanil (Lapudrine) in 2 healthy volunteers, after a single oral dose of the drug, was 14.7 and 16.1 h. No chlorcycloguanil could be detected in plasma over 32 h after dosing.
采用高效液相色谱法测定人血浆和尿液中氯胍和环氯胍的浓度。氯胍在血浆和尿液中的检测限为5 ng/ml,环氯胍为10 ng/ml。2名健康志愿者单次口服氯胍(拉布立林)后,氯胍的消除半衰期分别为14.7小时和16.1小时。给药后32小时内血浆中未检测到环氯胍。
