Atenolol

High blood pressure, angina (chest pain from reduced blood flow to the heart), and irregular heart rhythms.

Atenolol slows the heart rate and reduces the force with which the heart pumps. This lowers blood pressure and reduces the heart's oxygen demand, easing angina symptoms.

Adults with hypertension, angina or arrhythmias. Not suitable for people with severe asthma, heart block, or very low heart rate.
