Adrenergic Antagonists. Cause direct blockade of adrenergic receptors. With one exception, all produce reversible (competitive) blockade. Most adrenergic antagonists are more selective than the adrenergic agonists.. Chapter 13, . Stryer. Short Course. Signal Transduction. Signal from exterior of cell must affect interior of cell.

Adrenergic drugs (Sympathomimetic). Adrenergic drugs stimulate adrenergic receptors, thereby activating the sympathetic nervous system and inducing symptoms characteristic of the fight-or-flight response (sympathetic stimulation)..
