Therefore the Sprague-Dawley rat liver microsomes may be useful for assessing herb-drug interaction in the hepatic first-pass metabolism responsible for CYP1A2 at the early drug-discovery stage because of similar typical substrates and metabolism activities as humans. In medical terms, first-pass metabolism or presystemic metabolism is defined as the rapid uptake and metabolism of an active compound into inactive compounds by the liver, immediately after enteric absorption and before it reaches the systemic circulation.

Since the liver is the key player in metabolizing drugs, how to make vanilla lip scrub issues that affect it will also affect drug absorption. Factors that can affect the first-pass effect Since the gastrointestinal tract and liver are so important to first-pass metabolism, anything that significantly affects them will affect the intake of a substance.
