.Antagonist medications typically are considered?

A. Blocking agents: Antagonist medications block the action of other substances, typically by binding to receptors without activating them, thus preventing other substances from binding. B. Palliative care medications: These medications are used to relieve symptoms in patients with serious illnesses but do not describe how antagonist medications work. C. Diagnostic medications: These are used in diagnostic tests and procedures but do not describe the action of antagonists. D. Synergistic medications: Synergistic medications enhance the effects of each other when used together. This is the opposite of what antagonists do, as antagonists typically inhibit effects.
