Answer to Question 1

Interferons

Answer to Question 2

C
Feedback:
Some drugs are extensively metabolized in the liver, with only part of a drug dose reaching the systemic circulation for distribution to sites of action. This is called the first-pass effect or presystemic metabolism. The first-pass effect is not related to renal function or the need to pass through the bloodstream multiple times.
