Chemical antagonism can be non-receptor mediated. A common example of chemical antagonism is the scenario in which one drug can bind to and inactivate an agonist, thus making less of the drug available to produce an effect.

Introduction to Antagonism in Pharmacology. Antagonism could be defined as an interaction between two or more drugs that have opposite effects on the body. Drug antagonism may block or reduce the effectiveness of one or more of the drugs. In antagonism, there is always a competition for available receptor by two or more drugs or substances.

The newest -blocker, nebivolol, is selective for antagonizing 1-receptors and also increases nitric oxide mediated vasodilation. -Blockers such as labetalol and carvedilol also are not selective 1-blockers, but these drugs antagonize both - and -adrenergic receptors. By antagonizing -adrenergic receptors in the vasculature
