[Control of blood sugar and beta blockers in the diabetic patient]

30% of diabetics have arterial hypertension. 25% of patients with hypertension are diabetics. The rapid development of atherosclerosis is the main cause of morbidity and mortality among diabetics. Occasionally, prescription of a beta-blocking agent may seem rational in diabetics (hypertension, angina pectoris, etc.). But is such a medication acceptable considering the patient's fragile metabolic control? After a brief review of the pharmacology of the various beta-blocking agents, we discuss the choice of the best medication for the diabetic patient. Cardioselective beta-blockers seem to be best suited to diabetics. After insulin-induced hypoglycemia, rise in blood sugar level is less delayed and symptoms of hypoglycemia are less attenuated.
