What does a synergistic effect mean when two drugs are used together?

Explanation:
Synergy in drug interactions means the combined effect is greater than the sum of the effects of each drug given alone. This occurs because the drugs enhance each other's action, producing a larger overall response. This can allow lower doses to achieve the desired therapeutic effect, but it also increases the risk of stronger side effects or toxicity. If the two drugs together produced exactly the sum of their individual effects, that would be an additive interaction. If the combined effect were less than the sum, that would be antagonistic. An unpredictable or highly variable result wouldn’t reflect synergy.
