To determine the pharmacokinetics, safety and performance of a novel matrix formulation of fentanyl.
Transdermal fentanyl was administered as the novel matrix and the Durogesic reservoir formulations (24 subjects, 100 microg h(-1)) in a randomized, fully replicate, four-way crossover study. Serum concentrations of fentanyl were assayed by LC/MS/MS. Pharmacokinetic parameters of fentanyl and performance (adherence and skin irritability) were evaluated.
Test/reference ratio (90% confidence intervals) for AUC(0-t), AUC(inf) and C(max) were 105.5% (99.4, 112.0), 105.3% (99.3, 111.6) and 111.4% (100.4, 123.6), respectively. Adherence and skin irritability results of the two formulations were similar.
The two formulations are expected to result in similar efficacy for the management of severe pain.
确定一种新型芬太尼基质制剂的药代动力学、安全性和性能。
在一项随机、完全重复、四交叉研究中,将新型基质透皮芬太尼和多瑞吉储库制剂(24名受试者,100μg·h⁻¹)给药。采用液相色谱-质谱/质谱法测定血清中芬太尼浓度。评估芬太尼的药代动力学参数和性能(贴附性和皮肤刺激性)。
AUC(0-t)、AUC(inf)和C(max)的试验/对照比值(90%置信区间)分别为105.5%(99.4,112.0)、105.3%(99.3,111.6)和111.4%(100.4,123.6)。两种制剂的贴附性和皮肤刺激性结果相似。
预期这两种制剂在治疗重度疼痛方面疗效相似。
