Abstract

Acebutolol is a cardioselective beta-adrenoceptor blocking drug possessing both partial agonist (intrinsic sympathomimetic) and membrane stabilising activity. In hypertension, it can be administered once or twice daily with equal effectiveness, and has been as effective at lowering blood pressure as propranolol, diuretics, and other beta-blocking drugs (metoprolol, labetalol and atenolol) and more effective than methyldopa. Acebutolol has a significantly smaller effect on resting heart rate than propranolol, metoprolol and atenolol, although direct comparisons with drugs with intrinsic sympathomimetic activity have yet to be undertaken. In both angina and arrhythmia, when administered twice daily it has been as effective as standard therapeutic agents. The side effect profile of acebutolol appears to be comparable to that of other cardioselective beta-blockers. Its relative cardio-selectivity, partial agonist and membrane stabilising activity, hydrophilicity, and considerable extrarenal excretion may offer advantages over some beta-blocking drugs in specific patients. Choosing a beta-blocking agent, however, should be made with a knowledge of pharmacodynamic and pharmacokinetic properties of the various agents and careful consi...Continue Reading

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Antianginal Drugs: Mechanisms of Action

Antianginal drugs, including nitrates, beta-blockers, and calcium channel blockers, are used in the treatment of angina pectoris. Here is the latest research on their use and their mechanism of action.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
