Glycemic effects of various classes of antihypertensive drugs

From a recent review:

Core tip: Hypertension is a major contributor to the development and progression of cardiovascular disease. Increased blood pressure often coexists with insulin resistance. The various antihypertensive drugs have different effect on glucose metabolism. Indeed, angiotensin receptor blockers as well as angiotensin converting enzyme inhibitors have been associated with beneficial effects on glucose homeostasis. Calcium channel blockers are considered to have neutral metabolic effects. On the other hand, diuretics and β-blockers have an overall disadvantageous effect on glucose metabolism. As a result the metabolic effects of the various blood pressure lowering drugs should be taken into account when selecting an antihypertensive treatment.
