背景立即释放吗啡的最佳给药途径存在争议。吗啡已知的允许吸收的物理特性与舌下吗啡吸收更快这一未经证实的观点相反。目的本研究的目的是比较吞咽吗啡和舌下含服吗啡对血浆吗啡浓度 (PMC)、疼痛缓解和味觉的影响。方法 10 名患有癌症的参与者(平均年龄,50±12 岁)接受了 10 毫克吗啡片剂,采用随机交叉设计,重复前测量和后测量 60 分钟。测量指标包括 PMC 和疼痛缓解和味觉视觉模拟量表 (100 mm) 评分。结果最大 PMC 的个体间变异为 25 倍 (2.2–55 ng/mL)。 60 分钟时,舌下和吞咽途径的 PMC 曲线下平均面积(吞咽,329±314 ng/mL;舌下,314±299 ng/mL)或平均疼痛缓解评分(吞咽,81±32;舌下,78±31)没有显着差异。吞咽剂量后 5 分钟 (P<. 05)、10 分钟 (P<. 04)、15 分钟 (P<. 02) 和 20 分钟 (P<. 04) 的味觉评分明显低于舌下剂量后的不愉快程度。结论 在这种交叉设计中,舌下含服和吞咽吗啡的组间 PMC 相似,并产生相似水平的疼痛缓解。鉴于相同剂量后,参与者之间的 PMC 存在 25 倍的差异,因此有必要进行额外的研究来确定 PMC 巨大变异的根源。
BackgroundThe optimal route for immediate-release morphine administration is controversial. The known physical characteristics of morphine that allow absorption are counter to the unproven belief that sublingual morphine is absorbed more quickly.ObjectiveThe aim of this study was to compare swallowed and sublingual morphine for effects on plasma morphine concentrations (PMCs), pain relief, and taste.MethodsTen participants with cancer (mean age, 50±12 years) received a 10-mg morphine tablet in a randomized crossover design with repeated premeasure and postmeasure for 60 minutes. Measures included PMC and visual analog scale (100 mm) scores for pain relief and taste.ResultsInterindividual variability in maximum PMC was 25-fold (2.2–55 ng/mL). At 60 minutes, sublingual and swallowed routes were not significantly different for mean area under the curve for PMC (swallowed, 329±314 ng/mL; sublingual, 314±299 ng/mL) or for mean pain relief scores (swallowed, 81±32; sublingual, 78±31). Taste scores at 5 (P<. 05), 10 (P<. 04), 15 (P<. 02), and 20 (P<. 04) minutes after swallowed doses were significantly less unpleasant than after sublingual doses.ConclusionIn this crossover design, between-group PMCs were similar for sublingual and swallowed morphine and resulted in a similar level of pain relief. Given the 25-fold across-participant differences in PMC after the same dose, additional research is warranted to identify the sources of this tremendous variability in PMC.
