Nebivolol Hydrochloride is primarily used as a beta-blocker to treat high blood pressure (hypertension). It works by relaxing blood vessels and slowing the heart rate, which helps to improve blood flow and reduce blood pressure. This medication is often prescribed to manage chronic hypertension, reducing the risk of strokes, heart attacks, and kidney problems. Additionally, it is sometimes used in the treatment of heart failure, as it can improve heart function and reduce symptoms like shortness of breath and fatigue. Nebivolol Hydrochloride is also known for its vasodilatory effects, which are mediated through the release of nitric oxide, making it particularly effective in patients with endothelial dysfunction. It is generally well-tolerated and is often chosen for its favorable side effect profile compared to other beta-blockers.
