An agonist medication is defined as:

Explanation:
An agonist activates receptors to produce a response. When it binds, the receptor is stimulated and starts a cellular signaling cascade that mirrors the body’s own signaling molecules, leading to a physiological effect. This activation distinguishes agonists from other drug actions: blocking receptor activity describes antagonists, while destroying receptors or having no effect on receptors would not produce the receptor-mediated response that defines an agonist. So the description that the drug causes stimulation of receptors best captures what an agonist does.
