Explain first pass metabolism definition biology ppt

First-pass elimination takes place when a drug is metabolised between its site of administration and the site of sampling for measurement of drug concentration. Clinically, first-pass metabolism is important when the fraction of the dose administered that escapes metabolism is small and variable. Th . 5. First-pass metabolism: a type of metabolism in which drugs that are absorbed by the gastrointestinal tract go through the portal vein to the liver and are metabolized there before they are distributed to the general circulation. 6. Homeostasis: a balanced physiological process that protects and maintains the integrity of the internal envi-. of metabolism during this first pass through the stomach and liver (i.e., first-pass metabolism [FPM]). BAC is influenced by environmen-tal factors (such as the rate of alcohol drinking, the presence of food in the stomach, and the type of alcoholic bev­ erage) and genetic factors (variations in the principal alcohol-metabolizing.

Once you swallow that pill, it plops into the stomach. The stomach is a vat of acid. It has some very low pH so it's acidic.

We all know seriously acidic stuff can destroy even metal. Well, stomach acid can destroy some parts of a drug. As if that wasn't enough for the poor drug particles, next these guys are pumped out into the intestine from the stomach. It's not much safer here for what's left of the pill. The gastrointestinal tract can contribute significantly to the first pass effect. This happens in many ways.

Let's say that some part of the drug, or even most of the drug, has made it into the body from the gastrointestinal tract. Before it goes into general circulation, it has to pass through a gatekeeper. That gatekeeper is your liver. Your liver is like a explain first pass metabolism definition biology ppt. In any case, once the drug reaches the liver, a fraction of it will be metabolized. By most kisses videos video we mean the drug is transformed. This fraction is then sent into systemic body-wide circulation. Ergo, the total amount of the drug that makes it from biologh liver and into general circulation is less than what you originally took.

Because of the first pass metaboliismyour body receives less of a drug than you actually took. This refers to the fact that some of the drug that's taken orally is lost as it passes through the gastrointestinal system and the liver prior to reaching general circulation.
