背景:芬太尼口腔泡腾片(FEBT)旨在提高芬太尼(一种阿片类药物)通过口腔黏膜的吸收速率和程度。目的:本研究的目的是评估健康志愿者在潜在治疗剂量范围(100-800微克)内FEBT的剂量比例,并表征4个剂量(100、200、400和800微克)的FEBT药代动力学(PK)特征。方法:本I期随机、开放标签、4期交叉研究在夏威夷檀香山辐射研究中心进行。必威国际app对阿片类药物不耐受的健康成年志愿者被随机分配接受四种单剂量FEBT序列中的一种:100、200、400和800微克(选择包括预期治疗剂量范围),每次连续给药间隔>或=7天的洗脱期。盐酸纳曲酮(50 mg片)分别于FEBT给药前15、3小时和后9小时给药,以阻断芬太尼阿片受体介导的作用。从FEBT给药后72小时内获得的静脉样本中测量血浆芬太尼浓度。早期芬太尼暴露评估使用时间0至0.75小时的AUC(参考剂量[100微克]的中位T(max)) (AUC(0- tmax '))。在整个研究过程中,由合格的医学人员监测和记录不良事件。结果:32名受试者(26名男性,6名女性;平均[SD]年龄,29.3[7.2]岁[范围,19-44岁]; mean [SD] weight, 74.7 [10.7] kg) were enrolled. Median T was between 35 and 45 minutes after FEBT administration. AUC(0-infinity) and C(max) increased approximately linearly with increasing doses of FEBT. Mean plasma fentanyl concentrations decreased from C(max) in a biexponential manner at the 100- and 200-microg doses and decreased in a triexponential manner at the 800-mug dose. Despite the triexponential decrease in the mean profile observed with the 400-microg dose, a biexponential decrease was observed in approximately half of the individual profiles. AUC(0-Tmax') ranged from 0.09 ng x h/mL with the 100-microg dose to 0.52 ng x h/mL with the 800-microg dose. The most commonly reported AEs in the 100-, 200-, 400-, and 800-microg dose groups were as follows: application-site erythema, 3, 3, 4, and 3 subjects, respectively; nausea, 3, 2, 5, and 4 subjects; somnolence, 3, 2, 3, and 2 subjects; and headache, 3, 2, 1, and 4 subjects. None of the AEs were serious. CONCLUSIONS: In this study of the dose proportionality of FEBT in healthy volunteers, the PK profile of FEBT was characterized by a high early systemic exposure of fentanyl (0.09-0.52 ng x h/mL). Dose-dependent parameters (C(max) and AUC) increased in an approximately dose-proportional manner from 100 to 800 microg FEBT.
