摘要: 目的 比较食物对两种桂利嗪胶囊(A 和 B)人体生物利用度的影响。方法 用 HPLC 紫外检测法测 定健康受试者分别在禁食及餐后一次口服 50mg 桂利嗪胶囊 A 或 B 后血清药物浓度。结果 胶囊 A 的 Cmax 及 AUC 不受食物影响, 胶囊 B 的吸收受食物影响, 禁食后的 Cmax 和 AUC 显著低于餐后的 Cmax 和AUC。结论 胶囊 A 的制剂优于胶囊 B 的制剂, 其人体生物利用度不受食物影响。

Abstract: Aim To compare the effectsof food on the bioavailability of two kinds of cinnarizine capsules (A and B). Methods HPLC method with UV detection was used to measure the serum cinnarizine concentration in 12 healthy human volunteers after a single 50mg oral dose both in fasting condition and with a meal. Results The peak plasma concentration (Cmax)and the area under the plasma concentration time curve (AUC)of capsule A appeared to be unchanged in the presence of food, but food significantly affected the extent of absorption of capsule B. The Cmax and AUC of capsule B in fasting condition were significantly less than those with a meal. Conclusion The formulation of capsule A had advantage over capsule B. Its bioavailability was not affected by food.
