Arms and Interventions

Arm	Intervention/Treatment
Experimental: Healthy Volunteers Healthy volunteer received drug combinations（10 µg midazolam, 375 µg dabigatran etexilate, 10 µg pitavastatin, 50 µg rosuvastatin, and 100 µg atorvastatin） on an empty stomach	Drug: Midazolam, dabigatran etexilate, pitavastatin, rosuvastatin and atorvastatin Midazolam, dabigatran etexilate, pitavastatin, rosuvastatin and atorvastatin were provided by the Department of Pharmacy, Peking University Third Hospital, and were dissolved and mixed with normal saline respectively, and the mixing process needed to be fully stirred.
