Agonist. Definition. noun, plural: agonists. (pharmacology) A molecule that combines with a receptor on a cell to trigger physiological reaction. An example is an acetylcholine being the agonist that combines with the cholinergic receptor. (histology) A muscle that contracts while another muscle relaxes, e.g. when bending the elbow the biceps are the agonist.
Agonist Therapy. A drug that is an agonist attaches itself to receptors in the brain, and then produces a chemical reaction. For example, heroin is an opioid agonist. It binds to opioid receptors that control pleasure and pain, the result being a feeling of euphoria and well being. Other examples of opioid agonists, sometimes referred to as âfull agonists,â are oxycodone, morphine and opium. In agonist therapy, physicians prescribe their patients agonist drugs that attach themselves to the same receptors as the addicted substance.
