- Atenolol is a cardioselective, beta-1 adrenergic blocking agent, preferably in the heart.
- The principal physiologic action of Atenolol is to competitively block adrenergic receptors within the myocardium and within vascular smooth muscle. Atenolol also slows conduction in the atrioventricular (AV) node.
- Atenolol is effective for at least 24 hours after a single oral dose. Only about 50-60% of an oral dose of Atenolol is absorbed from gastrointestinal tract. Approximately 5% of Atenolol is bound to plasma protein and is well distributed in most tissues and fluids except brain and CSF. Patients with normal renal function, Atenolol has pasma half-life of 6 to 7 hours.
