Question

select the correct answer.
when two or more medicines are taken at the same time, they can work together in one of three ways: additive, synergistic, or antagonistic interaction.
what is synergistic interaction?
a. when two medicines work together in a positive way without causing any harm
b. when the effect of one medicine is reduced or cancelled by another one
c. when one medicine boosts the effect of the other one

Explanation:

To determine the correct answer, we analyze the definitions of each type of drug interaction:

• Option A describes an additive interaction (working positively without harm, like combined effect equal to sum).
• Option B describes an antagonistic interaction (one drug reduces/cancels another's effect).
• Option C: Synergistic interaction means one drug enhances (boosts) the effect of another, resulting in a combined effect greater than the sum of individual effects.

Answer:

C. when one medicine boosts the effect of the other one
