drug as an agonist or an antagonist
A drug antagonist is any drug that binds with a specific chemical receptor within the body, and in doing so, precludes another drug from binding to such a receptor and therefore stops the original drug from having an affect on the body. drug antagonist is any drug that binds with a specific chemical receptor within the body, and in doing so, precludes another drug from binding to such a receptor and therefore stops the original drug from having an affect on the body.
4. An agonist ties to a receptor site and causes a response whereas an antagonist works against the drug and blocks the response. 5. Agonists are also chemicals or reactions, which help in binding and also altering the function of the activity of receptors.. Agonist and antagonist act in opposite directions. When agonist produces an action, antagonist opposes the action. 2. Agonist works when the muscles relax and antagonist works when muscles contract.
Agonist: A substance that acts like another substance and therefore stimulates an action. Agonist is the opposite of antagonist.Antagonists and agonists are key players in the chemistry of the human body and in pharmacology.gonist: A substance that acts like another substance and therefore stimulates an action.
