The adrenergic inhibitors.

Abstract

Although most of the centrally and peripherally-acting adrenergic inhibitors have been available for several years, they continue to contribute importantly to antihypertensive therapy. There are remarkably few contraindications to their use. They are useful in hypertension of all grades of severity, and are also valuable in complicated forms of hypertension, such as those associated with renal insufficiency, diabetes mellitus, and chronic obstructive lung disease. They can produce some fairly predictable side effects in patients, but generally do not cause significant metabolic changes. These drugs also seem to be tolerated well by physically active patients. They appear to have desirable effects on cardiac structure. In general, the adrenergic inhibitors cause regression of a left ventricular hypertrophy, which may well be a valuable property, especially in older hypertensive patients.
