Effect of non-competitive antagonist on dose-response relationship

    Dose-response curve for an agonist drug with and without the presence of a noncompetitive (NC) antagonist. In the presence of a noncompetitive antagonist, the apparent maximal effect (Emax) of an agonist is decreased (indicated by arrows).
