Beta Blockers

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.
