Atenolol: A Complete Guide to Uses, Dosage, Side Effects, Mechanism & More
Atenolol is a selective β₁‑adrenergic blocker commonly prescribed for various cardiovascular conditions. As a hydrophilic β-blocker, Atenolol mainly targets the heart by reducing the activity of stress hormones like adrenaline. It slows down the heart rate and lessens the force of each beat, thereby lowering blood pressure and oxygen demand. Notably, Atenolol exerts minimal effects on the lungs and central nervous system, making it favourable for patients with respiratory concerns. Its reduced lipid solubility contributes to fewer CNS side effects, distinguishing Atenolol from older beta-blockers like propranolol
