This document discusses synergy, which refers to the combined effects of multiple elements being greater than the sum of their individual effects. It provides examples of drug synergy, where combining drugs can enhance or magnify their therapeutic effects or side effects. Positive synergy is exploited in combination drug preparations, while negative synergy can cause dangerous contraindications, such as combining CNS depressants. The key aspects of synergy discussed are that teamwork and interaction between elements produces effects that cannot be predicted by examining the elements individually.
