Drug- drug interaction is defined as which concept?

• A. The process of a drug working in the body
• B. The administration of different drugs to the same patient
• C. The interaction between a drug and a disease
• D. The interaction between drugs and foods

Answer: (B)

Drug-drug interactions happen when two or more medications taken together influence each other’s effects in the body, potentially increasing or decreasing efficacy or causing harm. The statement about administering different drugs to the same patient is the best fit because it describes the situation where such interactions can occur. The other options refer to how a single drug acts in the body, interactions between a drug and a disease, or interactions between drugs and foods, none of which define drug-drug interactions themselves. In real care, always consider how multiple meds may interact when a patient is on more than one medication.
