How is synergism defined in pharmacology?

Two medications have no effect when combined
Combined effect of medications is equal to the individual effects
The effect of two drugs together is greater than the effect of either alone
One drug nullifies the effects of the other drug

The correct answer is: The effect of two drugs together is greater than the effect of either alone

Synergism in pharmacology is defined as the effect of two drugs together being greater than the effect of either drug alone. This means that when two medications are combined, their effects are enhanced in a way that goes beyond simply adding up the individual effects of each drug. This can lead to a more potent therapeutic response or increased side effects.
