What term describes a therapeutic incompatibility where one drug reduces or cancels out the intended effect of another?

Answer

Antagonism

Antagonism is one of the two primary ways therapeutic incompatibilities manifest once drugs are interacting within the patient's body, affecting the expected clinical outcome. This interaction occurs when Drug A interferes with the mechanism of action of Drug B, thereby diminishing or completely nullifying the desired therapeutic response intended by Drug B. For instance, this can happen at the receptor level if one medication occupies the necessary binding sites, physically blocking the other drug from exerting its intended pharmacological effect. Understanding antagonism is crucial because it is a pharmacokinetic or pharmacodynamic issue that requires clinical awareness during concurrent prescription, even when the drugs are physically and chemically sound when mixed separately.
