Yes. Presystemic metabolization is the same as first-pass effect.


First-pass effect: This is an extremely important phenomenon to understand. Whenever the route of administration is such that there is an organ of elimination between the administration site and the systemic circulation, there is the potential for a first-pass effect. This is sometimes referred to as presystemic elimination. The consequence of the first-pass effect is that the fraction of drug reaching the systemic circulation is substantially reduced. This explains, for example, why the dose of propranolol that is administered intravenously is so much less than that administered orally. After oral administration, all of the drug must pass through the liver before reaching the systemic circulation. This results in exposure to drug metabolizing enzymes prior to the drug reaching the systemic circulation. The intestinal wall can also represent a site of first-pass metabolism. In later lectures, we will discuss the factors that influence the first-pass metabolism of drugs.
