• Status: Unknown status
• Trial end date: 1969-12-31
• Target enrollment: 0
• Participant gender: All

Summary

Ivabradine acts by inhibiting the ionic If current that modulates the pacemaker activity of sinoatrial node cells. The aim of present study is to evaluate the efficacy and safety of IvabRadine hemisulfate Sustained-release Tablets versus placebo in patients with moderate to severe chronic systolic heart failure.

• Phase: Phase 2/Phase 3
• Accepts Healthy Volunteers?: No
