Adrenoreceptor Blocker

Adrenoreceptor Blockers is a group of medications that are used in managing hypertension in patients. They act on adrenergic receptors such as beta-adrenergic or alpha-adrenergic receptors. The medications can lower the heart rate, the heart contractility, and vasomotor tone of the blood vessels. The main side effects of the beta-adrenergic blockers are fatigue, depression, or even serious hyperkalemia. And of course, the contraindications to beta-adrenergic blockers are conditions that associate with the depressed function of the heart such as Decompensated CHF or symptomatic bradycardia. It is also important to know the clearance mechanism of each individual beta-adrenergic blockers. Certain beta-adrenergic blockers are cleared via the Kidney, whereas others are cleared by the Liver. The Alpha-adrenergic blockers are too help with treating hypertension. However, alpha-adrenergic blockers’ actions are at the blood vessels, not the cardiac tissues.  The side effects of the alpha-adrenergic blockers are more profound than the beta-adrenergic blockers’. One important side effect one should pay attention to this group is the rebound hypertension or hypertensive crisis.
