Which type of drug interaction occurs when two drugs enhance each other's effects?

• A. Displacement
• B. Synergistic effects
• C. Hepatic metabolism
• D. Inhibition

Answer: (B)

The correct choice, synergistic effects, refers to a scenario where two drugs work together to produce a greater effect than either drug could achieve alone. This interaction occurs when the combined effect of the drugs is greater than the sum of their individual effects. For example, if Drug A lowers blood pressure by 10 mmHg and Drug B lowers it by 15 mmHg, together they might lower blood pressure by 30 mmHg, showing synergy. This concept is crucial in pharmacology as it can be beneficial in therapeutic contexts, allowing lower doses of each medication to be used, which can minimize side effects associated with higher doses of a single drug. Understanding these interactions helps healthcare professionals optimize treatment plans for patients by leveraging the synergistic effects to achieve desired health outcomes safely.
