<unk>  (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<unk>  especially in combination with thiazide-type diuretics carry an unacceptable risk of provoking type 2 diabetes.
Propranolol was the first clinically useful<unk>  adrenergic receptor antagonist. Invented by Sir James W. Black, it revolutionized the medical management of angina pectoris and is considered to be one of the most important contributions to clinical medicine and pharmacology of the 20th century.
