(Medicine) drug that blocks stress hormones by hindering the activity of beta receptors in the body (used to treat hypertension, angina, and other heart conditions)
Beta blockers (sometimes written as β-blockers) are a class of
drugs used for various indications, but particularly for the management of
cardiac arrhythmias and cardioprotection after
myocardial infarction. Whilst once first-line treatment for
hypertension, their role was downgraded in June 2006 in the
United Kingdom to fourth-line as they do not perform as well as other drugs, particularly in the elderly, and there is increasing evidence that the most frequently used beta-blockers especially in combination with thiazide-type diuretics carry an unacceptable risk of provoking
type 2 diabetes.
