Agonists and Antagonists. An agonist is a drug that binds to receptors and thereby alters (stabilizes) the proportion of receptors that are in the active conformation, resulting in a biologic response. A full agonist results in a maximal response by occupying all or a fraction of receptors.t considers both drug action, which refers to the initial consequence of a drug-receptor interaction, and drug effect, which refers to the subsequent effects. The drug action of digoxin, for example, is inhibition of membrane Na + /K + -ATPase; the drug effect is augmentation of cardiac contractility.
Butorphanol is a mixed opiate agonist/antagonist that may block the effects of opiate agonists and reduce analgesic effects. Butorphanol may cause withdrawal symptoms in patients receiving chronic opiate agonists. Concurrent use of butorphanol with other opiate agonists can cause additive CNS, respiratory, and hypotensive effects. The additive or antagonistic effects are dependent upon the dose of the opiate agonist used; antagonistic effects are more common at low to moderate doses of the opiate agonist.
