100mg Atenolol Tablets BP contains the active ingredient atenolol, which is a beta-blocker medication used primarily to treat high blood pressure (hypertension), angina (chest pain), and certain types of cardiac arrhythmias (irregular heartbeats). It helps to lower blood pressure and reduce the workload on the heart, which can be beneficial for individuals with hypertension, angina, or certain heart rhythm disorders. This works by blocking the effects of adrenaline on the heart, thereby slowing down the heart rate and reducing the force of contraction of the heart muscle. 100mg Atenolol Tablets BP adhere to the standards set by the British Pharmacopoeia (BP), ensuring their quality, purity, and efficacy.
