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.
An antagonist is an agent that binds to a receptor but does not elicit the response that the neurotransmitter or an agonist would cause. The antagonist blocks the receptor and prevemts activation by neurotransmitters or other drugs. So in the case of opiates, lets look at the opiate agonist, morphine.When morphine enters the brain, it binds to opiate receptors and activates them. This binding is what produces the effects of Morphine.he antagonist blocks the receptor and prevemts activation by neurotransmitters or other drugs. So in the case of opiates, lets look at the opiate agonist, morphine. When morphine enters the brain, it binds to opiate receptors and activates them.
