Hibesor 50mg Tablet contains Atenolol, a selective beta-1 adrenergic receptor blocker primarily used in the management of cardiovascular conditions. Atenolol exerts its therapeutic effects by reducing heart rate, myocardial contractility, and cardiac output, thereby decreasing oxygen demand and workload on the heart. It is indicated for the treatment of hypertension, angina pectoris, and for secondary prevention following myocardial infarction. By blocking beta-1 receptors in the heart, Hibesor helps to control elevated blood pressure, reduce the frequency and severity of angina attacks, and improve survival rates post-heart attack. The 50mg dosage is commonly prescribed for adults, with adjustments made based on clinical response and tolerability. Hibesor is generally well-tolerated; however, caution is advised in patients with bradycardia, heart block, or severe peripheral arterial disease. Common adverse effects may include fatigue, dizziness, and cold extremities. It is contraindicated in patients with hypersensitivity to atenolol, severe bradycardia, cardiogenic shock, or uncompensated cardiac failure. Patients should be monitored regularly for blood pressure, heart rate, and signs of adverse reactions during therapy. Hibesor should be used under medical supervision, with adherence to prescribed dosage and duration for optimal therapeutic outcomes.
