ginas father has diabetes and takes insulin. he recently had a liver transplant, after which he was put on anti - rejection med insulin less effective.
which term best characterizes ginas fathers situation?
a. synergistic interaction
b. antagonistic interaction
c. additive interaction

Explanation:

To determine the correct term, we analyze the drug interaction:

• Antagonistic interaction occurs when one drug reduces the effectiveness of another. Here, the anti - rejection medication makes the insulin less effective.
• Synergistic interaction is when drugs work together to have a greater effect, which is not the case here.
• Additive interaction is when the combined effect is the sum of individual effects, which also does not match this situation.

Answer:

B. antagonistic interaction
