Ranolazine, a novel antianginal drug, treats stable angina pectoris by inhibiting the late sodium current. This mechanism reduces intracellular sodium and calcium overload during ischemia, without affecting heart rate or blood pressure.
Area of Science:
- Cardiovascular Pharmacology
- Electrophysiology
- Ischemic Heart Disease
Context:
- Stable angina pectoris is a common cardiovascular condition.
- Current antianginal therapies can affect hemodynamics.
- Understanding novel mechanisms of action is crucial for treatment advancements.
Purpose:
- To introduce ranolazine as a novel therapeutic agent for stable angina.
- To elucidate the electrophysiological mechanism of ranolazine's action.
- To explore ranolazine's potential in other cardiovascular conditions.
Summary:
- Ranolazine is a new drug for stable angina pectoris.
- It selectively inhibits the persistent or late sodium current (I(Na,late)).
- This inhibition reduces intracellular sodium and calcium overload, mitigating ischemic effects without altering heart rate or blood pressure.
Impact:
- Ranolazine offers a new treatment option for angina without hemodynamic compromise.
- Its mechanism suggests potential utility in managing atrial fibrillation and diastolic heart failure.
- Provides a novel approach to managing myocardial ischemia.

Antianginal Drugs: Calcium Channel Blockers and Ranolazine
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...
Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
