Study of Remimazolam Tosilate in Patients Undergoing Colonoscopy

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the safety and efficacy of the sedation for Remimazolam or Propofol in patients undergoing colonoscopy.

Detailed Description
-----------------
This is a multi-center, parallel-group, single blind study using Remimazolam or propofol for sedation in patients undergoing colonoscopy.Subjects are randomized to different treatment groups (including 1 for Remimazolam Tosilate and 1 for propofol). Fentanyl are permitted before colonoscopy. Efficacy and safety profiles of Remimazolam Tosilate are to be evaluated.
