Clinical Trial Summary

A Randomized, Open-label, Single Dose, Two Formulation, Two Period, Double Cross Over Bioavailability Comparison Study of two types of Nimodipine Injections in Healthy Volunteers.

Description:

The investigation product Nimodipine Injection (II) was supplied by Shenyang Dongxing Pharmaceutical Technology Co., Ltd.And Nimodipine injection (trade name: Nimotop) manufactured by Bayer Pharma AG was used as the reference preparation.The volunteers were administered with Nimodipine injection for intravenous infusion (containing nimodipine 11 mg) for 12 consecutive hours, respectively.The Venous blood was collected at 0 hours before the administration (ie, 1 hour before the administration) and 10 minutes, 20 minutes, 30 minutes, 45 minutes, 1 h, 2 h, 3 h, 4 h, 6 h, 8 h, 10 h, 12 h (Administration was over) and 12.5 h, 13 h, 14 h, 16 h, 19 h, 22 h, 25 h, 36 h, 3 ml per blood collection.
