Chapter 24, Problem 3RQ
What is synergistic effect?
Expert Solution & Answer
To determine
The meaning of synergistic effect.
Answer to Problem 3RQ
Synergistic effect is the effect produced due to interaction of two drugs as a result of which the combined effect of drugs gets amplified.
Explanation of Solution
Synergism has been derived from the Greek word "synergos" that literally means working together. Synergistic effect is based on the fact “one plus one is greater than two. Thus synergistic effect is the combined effect produced due to interaction of two drugs having different primary activities but common secondary activity. Upon interaction one drug enhances the action of another and the effect that both the drugs share is amplified. Synergistic effect is produced when two drugs with different primary activities but similar secondary activity interact. The common effect that they share gets maximized upon interaction. This is because one helps the other in enhancing its effect.
Conclusion:
Therefore, synergistic effect is the effect produced due to interaction of two drugs as a result of which the combined effect of drugs gets amplified.
