Some other tissues show considerable activity, for example the gastrointestinal tract, the lungs, the skin, the kidneys and the brain. As a result, in cases of some drugs, only a small proportion of the active drug reaches the systemic circulation and its intended target tissue. In cases of those drugs, which has high first-pass effect, oral administration is avoided, to get the desired effect.

The liver is usually describe first pass effect definition economics to be the major site of first-pass metabolism of describee drug administered orally, pxss other potential sites are the gastrointestinal tract, blood, vascular endothelium, lungs, and the arm from which venous samples are taken. Bioavailability, defined as the ratio of the areas under the blood concentration-time curves, after extra- and intravascular drug administration corrected for dosage if necessaryis often used as a measure of the how to monitor my childs messages account of first-pass metabolism. When several sites of first-pass metabolism are in describe first pass effect definition economics, the bioavailability is the product of the fractions of drug entering the tissue that escape loss at each site.
The extent of first-pass metabolism in the liver and intestinal wall depends on a number of physiological factors. The major factors are enzyme activity, plasma protein and blood cell binding, and gastrointestinal motility. Models that describe the dependence of bioavailability on changes in these physiological variables have been developed for drugs subject to first-pass metabolism only in the liver. Two that have been applied widely are the 'well-stirred' and 'parallel tube' models. Discrimination between the 2 models may be performed under linear conditions in which all pharmacokinetic parameters are independent of concentration and time.
The predictions of the models are similar when bioavailability is large but differ dramatically when bioavailability is small.
