Question

Mr PL was administered Drug A that acts on a particular receptor. Unfortunately, it was given in overdose and produced an adverse effect. Drug B is then administered which blocks that receptor. The effect of drug B results in a reduction in the effect of drug A. Comment on if Drug B is acting competitively (reversibly) or non-competitively (irreversibly)? Provide one suitable clinically relevant example of such interaction.
