摘要: 目的: 研究黄杨宁口腔速崩片的人体相对生物利用度和生物等效性。方法: 22 名健康男性受试者, 随机分组双交叉给予黄杨宁口腔速崩片(受试制剂) 和黄杨宁片(参比制剂), 剂量均为2 mg, 间隔为2 周。分别于给药后120 h 内多点抽取静脉血, 血浆样品经固相萃取(SPE) 后用液质联用技术测定其中环维黄杨星D 浓度。DAS 2.0药动学程序计算相对生物利用度并评价两者的生物等效性。AUC0-120、AUC0-inf 和Cmax经方差分析和双单侧t 检验, tmax 进行秩和检验。结果: 单剂量给予受试制剂、参比制剂后血浆中的环维黄杨星D 的Cmax分别为(121±55)、(122±52) ng/L;tmax 分别为(10±7)、(12±8) h;AUC0-120 分别为(4398±1656)、(4524±1760) ng·L-1·h;AUC0→inf 分别为(5292±2034)、(5440±2446) ng·L-1·h 。Cmax的90%可信区间为82.7%~117.3%;AUC0-120 的90% 可信区间为83.9%~112.9%;AUC0→inf 的90% 可信区间为83.4%~117.6%。结论: 受试制剂的人体相对生物利用度为(97.7±14.7)%, 与参比制剂相比, 两者具有生物等效性。

Abstract: AIM: To study the relative bioavailability and bioequivalence of cyclovirobuxine D orally disintegrating tablets and cyclovirobuxine D tablets in healthy volunteers. METHODS: 2 mg of cyclovirobuxine D orally disintegrating tablets and cyclovirobuxine D tablets was given to 22 healthy volunteers in a randomized crossover study. The concentration of cyclovirobuxine D in plasma was determined by LC/MS/MS after a solid phase extraction (SPE).The pharmacokinetic parameters were calculated and the bioavailability and bioequivalence of two formulations were evaluated by DAS 2.0 software. RESULTS: After a single dose, the pharmacokinetic parameters of cyclovirobuxine D and reference were as follows:Cmax, (121±55) and (122±52) ng/L;tmax, (10±7) and (12±8) h;AUC0-120 h, (4398±1656) and (4524±1760) ng·L-1·h;AUC0→inf, (5292±2034) and (5440±2446) ng·L-1·h, respectively.The 90% confidential interval of Cmaxof cyclovirobuxine D orally disintegrating tablet was 82.7%-117.3%.The 90% confidential interval of AUC0-120 and AUC0→inf of cyclovirobuxine D orally disintegrating tablet were 83.9%-112.9% and 83.4%-117.6%, respectively. CONCLUSION: The relative bioavailability of cyclovirbuxine D orally disintegrating tablets to cyclovirobuxine D tablets is (97.7±14.7)%.The results of the statistic analysis show that the test and reference formulations are bioequivalent.
