摘 要:采用单剂量随机交叉试验设计,评价10只Beagle犬口服盐酸鲁拉西酮片受试和参比制剂的相对生物利用度。用UPLC-MS/MS法测定血浆中的鲁拉西酮。鲁拉西酮在0.1~300.0 ng/ml范围内线性关系良好,最低定量限(LLOQ)为0.1 ng/ml。10只Beagle犬口服盐酸鲁拉西酮片,受试和参比制剂的主要药动学参数为:t_(max)(0.8±0.2)和(0.8±0.5)h;c_(max)(51.1±50.1)和(66.4±75.5)ng/ml,AUC_(0→t)(162.9±97.2)和(175.9±123.7)ng·h·ml^(-1),AUC_(0→∞)(178.0±99.1)和(183.9±124.3)ng·h·ml^(-1),t_(1/2)(16.6±8.8)和(15.7±4.4)h。受试制剂中盐酸鲁拉西酮的相对生物利用度为(92.6±43.8)%。两制剂的平均药动学参数没有统计学差异。A randomized single-dose cross-over design was used to evaluate the relative bioavailability of lurasidone hydrochloride tablets in ten Beagle Dogs. The drug concentration of lurasidone in plasma was determined by UPLC-MS/MS. It was linear for lurasidone in the range of 0.1- 300.0 ng/ml. Its low limit of quantification was 0.1 ng/ml. The main pharmacokinetic parameters of the test and the reference preparations in Beagle dogs after oral administration of lurasidone hydrochloride tablets were as follows: t_(max)(0.8±0.2) and(0.8±0.5) h, c_(max)(51.1±50.1) and(66.4±75.5) ng·ml^(-1), AUC_(0→t)(162.9±97.2) and(175.9±123.7) ng·h·ml^(-1), AUC_(0→∞)(178.0±99.1) and(183.9±124.3) ng·h·ml^(-1), t_(1/2)(16.6±8.8) and(15.7±4.4) h. The relative bioavailability of the test preparation was(92.6±43.8)%. There was no significant difference between the test and the reference preparations.
