【目的】比较研究布洛芬混悬液和市售布洛芬片的生物利用度和药代动力学。【方法】选择8 名健康男性志愿者,随机分为两组,进行单次混悬液或片剂交叉给药600 m g 后,利用 H P L C 法测定血浆中布洛芬浓度。【结果】两组血浆的布洛芬浓度分别在(0 .92 ±0 .33) 和(1 .68 ±0 .51) h 达到峰值(13 .88 ±1 .92) 和(11 .07 ±2 .51) μg/ml。血药浓度曲线下面积( A U C) 分别达(47 .77 ±3 .46) 和(45 .23 ±5 .21) μg/( min·ml) ,混悬液的相对生物利用度( F) 为(105 .6 ±11 .3) % 。【结论】布洛芬混悬液和市售布洛芬片两种制剂具有生物等效性。
【Objective】 To compare the bioavailability and pharmacokinetics of ibuprofen suspension and commercial ibuprofen tablets. 【Methods】 Eight healthy male volunteers were randomly divided into two groups. After a single suspension or tablet crossover administration of 600 m g, the plasma concentration of ibuprofen was determined by H PLC method. [Results] The plasma concentrations of ibuprofen peaked at (0.92 ± 0.33) and (1.68 ± 0.51) h (13.88 ± 1.92) and (11.07 ± 2 .51) μg / ml. The area under the plasma concentration curve (AUC) was (47.77 ± 3.46) and (45.23 ± 5.21) μg / (min · ml), respectively. The relative bioavailability ) Was (105.6 ± 11.3)%. 【Conclusion】 Both ibuprofen suspension and commercial ibuprofen tablets have bioequivalence.
