Physiologic antagonists
Physiological agonism describes the action of a substance which ultimately produces the same effects in the body as another substance—as if they were both agonists at the same receptor—without actually binding to the same receptor. Physiological antagonism describes the behavior of a substance that produces effects counteracting those of another substance (a result similar to that produced by an antagonist blocking the action of an agonist at the same receptor) using … WebbThe beta-adrenoceptor agonists have become the cornerstone of bronchodilator therapy. These agents are "functional" or "physiologic" antagonists that actively relax airway …
