What does the term 'drug synergy' refer to in pharmacology?

The term 'drug synergy' in pharmacology refers to the phenomenon where the combined effect of two drugs is greater than the sum of their individual effects. This concept is significant because it illustrates how certain drugs can work together in a way that enhances their overall therapeutic effect. For example, in treating specific conditions, one drug may enhance the effect of another, making the treatment more effective than if each drug were used alone. This can be particularly beneficial in situations where higher doses of a single drug might lead to increased side effects. Understanding synergy allows healthcare providers to optimize treatment regimens, improving patient outcomes by leveraging the strengths of multiple drugs working in concert.
