Angina: Most patients with angina pectoris will respond to 100mg daily given as a single or divided dose. It is unlikely that additional benefit will be gained by increasing the dose.
Hypertension: 100mg daily. Most patients respond to 100mg daily given as a single dose. The effect of the initial dose will be fully established after one to two weeks. A further reduction in blood pressure may be achieved by combining Atenolol with other antihypertensive agents. For example co-administration of Atenolol with a diuretic provides a highly effective and convenient antihypertensive therapy.
Patients can be transferred to VASCOTEN from other antihypertensive treatments with exception of clonidine (see Precautions).
