List and describe the mechanism of action, therapeutic indications, and adverse effects of adrenergic and -adrenergic blocking agents. Adrenergic drugs are those chemical agents that exert their principal pharmacologic and therapeutic effects by acting at peripheral sites to either enhance or reduce the activity of components (adrenaline) of the sympathetic division of the autonomic nervous system. INTRODUCTION. • Adrenergic antagonists are classified according to their relative affinities for α or β receptors in the peripheral nervous system. Adrenergic Antagonists These drugs act by either reversibly or irreversibly attaching to the receptor, thus preventing its activation by endogenous catecholamines.
