Description: Atenolol is a selective β1 receptor antagonist. It belongs to the group of beta blockers (sometimes written β-blockers), a class of drugs used primarily in cardiovascular diseases. Atenolol was developed as a replacement for propranolol in the treatment of hypertension. It works by slowing down the heart and reducing its workload. Unlike propranolol, atenolol does not pass through the blood–brain barrier to a large extent thus decreasing the incidence of various central nervous system side effect.
