Atlol Tablets (Atenolol) are a prescription medication used to treat high blood pressure, chest pain (angina), and certain heart rhythm disorders. Atenolol is a beta-blocker that works by slowing down the heart and reducing the workload on the heart, which helps to lower blood pressure and improve blood flow. These tablets are available in various strengths and are typically taken once daily, with or without food. It is important to follow the dosage and instructions provided by your doctor or pharmacist and not to stop taking the medication abruptly, as it may lead to worsening of your condition. Before starting Atenolol, it is important to inform your healthcare provider about any other medications you are taking and any underlying medical conditions you may have.
