What is the main organ of biotransformation?
The liver
What is the primary site of drug biotransformation?
The liver
Which enzyme system is mainly involved in drug biotransformation in the liver?
CYP450 enzyme system
Think: “Live(r) to transform
”The liver “lives” to transform drugs into a form the body can eliminate.
Term: CYP450 Inducer
Definition: A medication that increases the clearance of other drugs by
accelerating their metabolism through the CYP450 enzyme system.
What is the effect of an inducer on drug metabolism?
Increases metabolism
What is the result of increased metabolism on drug clearance?
Drugs leave the body faster
What is the effect of an inhibitor on drug metabolism?
Inhibits metabolism
What is the result of inhibited metabolism on drug levels in the body?
Keeps drugs around longer
Term: CYP450 Inhibitor
Definition: A drug that decreases the clearance of other medications by
slowing down their metabolism via the CYP450 enzyme system.

What is First-Pass Metabolism?
The process where an oral drug is metabolized in the liver after absorption
from the small intestine.
What effect does First-Pass Metabolism have on drugs?
