Lebetalol is primarily utilized as an antihypertensive agent, and its main therapeutic effect is to decrease heart rate and blood pressure. It accomplishes this through a mechanism that blocks both alpha and beta-adrenergic receptors. By blocking the beta-1 receptors in the heart, it reduces heart rate and myocardial contractility, which directly lowers cardiac output. Additionally, its action on alpha-1 receptors results in vasodilation, contributing to a decrease in systemic vascular resistance and, therefore, blood pressure.

This dual action makes Lebetalol particularly effective in managing conditions like hypertension and hypertensive emergencies. In clinical practice, it is important for healthcare providers to understand that by decreasing heart rate and blood pressure, Lebetalol helps improve cardiovascular function and reduce the risk of complications associated with high blood pressure.

Other options present effects that are either not relevant to Lebetalol’s mechanism of action or pertain to different medications. For example, increasing heart rate and contractility would oppose the therapeutic goals of using Lebetalol, and while it does have vasodilatory properties, its primary role relates specifically to the overall reduction of heart rate and blood pressure. Similarly, stabilizing blood glucose levels is outside the pharmacological scope of Lebetalol
