Ranolazine: clinical applications and therapeutic basis
1Internal Medicine Institute, Cleveland Clinic, Cleveland, OH 44195, USA.
Summary
Ranolazine effectively treats chronic angina by inhibiting late sodium channels, improving exercise capacity and reducing episodes without adverse hemodynamic effects. Its safety profile is favorable, even in patients with structural heart disease.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Ranolazine is approved for chronic angina.
- Its mechanism involves late sodium channel inhibition.
Purpose of the Study:
- To review experimental and clinical data on ranolazine's current use.
- To explore potential future applications in cardiovascular conditions.
Main Methods:
- Review of randomized clinical trials.
- Analysis of experimental data on ion channel effects.
Main Results:
- Ranolazine improves exercise capacity and reduces angina episodes.
- It lacks the hemodynamic effects of conventional antianginal agents.
- Minimal QTc prolongation observed, with no increased risk of torsades de pointes.
Conclusions:
- Ranolazine offers a unique therapeutic option for chronic angina.
- Its mechanism suggests potential roles in ischemic heart disease, arrhythmias, and heart failure.
- Ranolazine demonstrates a favorable safety profile in patients with structural heart disease.

01:25Antianginal Drugs: Calcium Channel Blockers and Ranolazine
Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
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...

01:22Antiarrhythmic Drugs: Class I Agents as Sodium Channel Blockers
Class I antiarrhythmic drugs are used to treat various types of arrhythmias or irregular heart rhythms. These drugs block the sodium (Na+) channels in the cardiac cells, thereby affecting the movement of electrical impulses across the heart. Class I antiarrhythmic drugs are divided into three subgroups: Class IA, Class IB, and Class IC, each with distinct mechanisms of action and effects on the heart.

01:24Antiarrhythmic Drugs: Class II Agents as β-Adrenergic Blockers
Adrenergic stimulation generally impacts cardiac rate and rhythm. Specifically, stimulation of the β-adrenoceptors triggers an increase in intracellular calcium ion influx and pacemaker currents, which may cause arrhythmias. Catecholamines like adrenaline also demonstrate β2-adrenoceptor-mediated hypokalemia, impacting cardiac action potential and disrupting the normal cardiac rhythm. Class II antiarrhythmic drugs are β-adrenoceptor antagonists or β-blockers, which indirectly block calcium...
01:12Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers
Class III antiarrhythmic drugs are a group of medications that can prolong action potentials in the heart. They achieve this by blocking potassium channels or enhancing inward currents from sodium channels. However, these drugs have a unique property of "reverse use-dependence," which is most pronounced at slower heart rates and can lead to torsades de pointes—a specific type of arrhythmia. However, it is essential to note that excessive QT interval prolongation—a measure of the heart's...
01:20Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers
Class IV antiarrhythmic drugs, such as verapamil and diltiazem, block calcium channels. They primarily affect the heart, slowing the conduction in calcium-dependent tissues like the SA and AV nodes. These drugs manage reentrant supraventricular tachycardia (SVT) and reduce ventricular rate in atrial flutter/fibrillation.
Verapamil, a calcium channel blocker, inhibits calcium movement across myocardial cell membranes and vascular smooth muscle. This results in the dilation of coronary and...

01:18Cardiovascular Drugs: Classification based on Therapeutic Indications
Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However, frequent irregular...
