Byscard 2.5mg Tablet: A Comprehensive Overview
Introduction
Byscard 2.5mg tablets, containing the active ingredient nebivolol, are a widely used medication for managing high blood pressure (hypertension) and improving exercise tolerance in patients with heart failure. As a beta-blocker, nebivolol plays a crucial role in cardiovascular health by affecting heart rate and blood vessel function.
Mechanism of Action
Nebivolol, the active component of Byscard 2.5mg, belongs to a class of drugs known as beta-blockers. These medications work by blocking beta-1 receptors in the heart. Normally, these receptors bind to catecholamines, hormones that increase heart rate and force of contraction. By inhibiting this binding, nebivolol helps the heart to beat more slowly and with less force¹².
Additionally, nebivolol promotes the relaxation of blood vessels, which further aids in lowering blood pressure. This dual action not only reduces the workload on the heart but also helps in preventing complications such as heart attacks and strokes¹².

Byscard 2.5mg is primarily used for:
Treating High Blood Pressure (Hypertension): By lowering blood pressure, it reduces the risk of cardiovascular events like heart attacks and strokes¹².
