Study highlights beta-blocker misunderstanding

Beta-adrenoceptor blockers are being prescribed at unnecessarily high doses for cardiac failure when evidence shows they are just as effective at lower doses, says an Australian professor of medicine and pharmacology.

Dr Simon Dimmitt, Medical Director of the Australian Community & Health Foundation (pictured), says doses near the top of the dose-response curve may cause unintended effects and significant morbidity such as hypotension and bradycardia without increasing benefits.
