Abstract

Atenolol is a beta-selective (cardioselective) adrenoceptor blocking drug without partial agonist or membrane stabilising activity. Its profile of action most closely resembles that of metoprolol which differs only in that it has some membrane stabilising activity. Atenolol has been well studied and is effective in the treatment of hypertension and in the prophylactic management of angina. Its narrow dose response range obviates the need for highly individualised dose titration. In patients with angina its long duration of beta-blocking activity allows once daily dosage, whereas other beta-blockers, unless in sustained release dosage forms, need to be given in divided doses. Other beta-blockers can be given once daily in hypertension, but at presnt the evidence for effective control with a once daily regimen is more convincing with atenolol. Further studies are need to clarify any important differences in blood pressure control between the various beta-blocking drugs, both in conventional or sustained release dosage forms. As with metoprolol, atenolol is preferable to non-selective beta-blockers in patients with asthma or diabetes mellitus. Atenolol has been well tolerated in most patients, its profile of adverse reactions generally resembling that of other beta-blocking drugs, although its low lipid solubility and limited penetration into the brain results in a lower incidence of central nervous system effects than seen with propranolol. Atenolol is eliminated virtually entirely as unchanged drug in the urine and dosage needs to be reduced in patients with moderate to severely impaired renal function (glomerular filtration rate less than 30 ml/min). There is no need for modification of dosage of atenolol in liver disease.
