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.ntagonist therapy has several benefits.

In this way, an antagonist can block the effects of agonists, whether those agonists are drugs or neurotransmitters.Some alcohol antagonists are receptor antagonists, but many are not. Do not be confused. receptor antagonist can block other ligands from binding. In this way, an antagonist can block the effects of agonists, whether those agonists are drugs or neurotransmitters.
