What class of drugs do beta-blockers belong to?

Beta-blockers are primarily classified as antihypertensives because they are frequently used to manage hypertension (high blood pressure). These medications work by blocking the effects of adrenaline (epinephrine) on beta-adrenergic receptors, leading to a decrease in heart rate and the force of contraction. This results in lowered blood pressure, making beta-blockers effective for treating conditions associated with cardiovascular health, including heart failure, arrhythmias, and angina.

In addition to their role in hypertension management, beta-blockers can also have effects on heart rate and myocardial oxygen demand, thereby offering benefits in various cardiovascular conditions. Their primary role, however, in this context is recognized under the category of antihypertensives, reflecting their key function in reducing blood pressure.
