    Details Below:
    Atenolol is a cardioselective beta-adrenoceptor blocker that is used in hyper-
    tension and in angina. The recommended daily dose for atenolol in hyper-
    tension is 25–100 mg, although the 50 mg dose is usually adequate. As a
    beta-blocker it may mask symptoms of hypoglycaemia. However, this is of no
    concern in AB as the patient is not taking any antidiabetic agents but is control-
    ling diabetes through diet. Beta-blockers have negative inotropic properties
    and therefore may cause bradycardia and they should not be used in patients
    with uncontrolled heart failure. Treatment with beta-blockers such as atenolol
    should be started with care in patients with heart failure. It has been demon-
    strated that three beta-blockers namely bisoprolol, carvedilol, and metoprolol
    reduce heart failure disease progression, decrease symptoms and mortality
    when used in stable heart failure. In AB it is an option to consider changing
    atenolol to an alternative therapeutic approach which better tackles the
    concomitant occurrence of hypertension and congestive heart failure. Use of
    one of these three beta-blockers (bisoprolol, carvedilol, and metoprolol) is an
