Summary

The relationship between oral dose and plasma concentration of the long acting cardioselective β-blocker, atenolol, and the antihypertensive response to the degree of β-blockade and change in plasma renin activity was evaluated in 20 patients with mild-to-moderate hypertension in a double-blind, randomised, between-patient, dose-ranging (25, 50 or 100mg once daily for 4 weeks) study. It is concluded that being unmetabolised and renally excreted, atenolol has a long biological action with a mean elimination half-life of approximately 10 hours. This enables a low dose to be given on a once daily basis, resulting in 24-hour cover for mild-to-moderate essential hypertension.
