Ivabradine reduces heart rate by inhibiting the cardiac pacemaker current. A common side effect is visual disturbances, but it can treat angina when beta-blockers are ineffective if heart rate is over 60 bpm.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Ivabradine targets the cardiac pacemaker If current, crucial for diastolic depolarization.
- Beta-blockers are standard for angina, but some patients require alternative treatments.
Purpose of the Study:
- To summarize the mechanism, side effects, and therapeutic indications of Ivabradine.
Main Methods:
- Review of Ivabradine's pharmacological action.
- Analysis of clinical trial data regarding efficacy and safety.
Main Results:
- Ivabradine selectively inhibits the If current, lowering heart rate.
- Phosphenes (light flashes) are the primary side effect.
- Effective in angina patients unresponsive to beta-blockers if baseline heart rate ≥ 60 bpm.
Conclusions:
- Ivabradine offers a valuable therapeutic option for angina pectoris.
- Patient selection requires consideration of heart rate and prior treatment response.
