The drug is also widely prescribed for post-heart attack patients because it can reduce the heart's workload and reduce the risk of further complications. Atenolol belongs to the beta-blocker drug class and is cardioselective, meaning it targets specific receptors in the heart and can be useful for patients who want to improve their heart regulation without broader systemic effects. Side effects can occur, but most resolve as patients adapt to the new medication."}
