Absorption refers to the process by which molecules or particles are taken into an absorptive system. In biological systems, this is commonly used to describe the intake of nutrients and other molecules from the digestive tract into the bloodstream. In general, absorption is characterized by the transfer of one substance into another, typically from a higher concentration to a lower concentration until equilibrium is reached.

In the context of pharmacology, absorption is an important step in the process of drug delivery. Different drug formulations and routes of administration (such as oral, sublingual, intravenous, transdermal, etc.) can impact the rate and extent of absorption of a drug. For example, an oral medication must pass through the stomach and intestinal lining before it can enter the bloodstream, which can slow down or delay absorption.

Factors that can affect absorption include solubility, particle size, pH, and chemical properties of the substance being absorbed. In addition, the presence of food, liquids, or other substances in the body can impact absorption rates.

Overall, understanding the principles of absorption is important for the development of more effective drugs and treatments, as well as for optimizing our ability to absorb and utilize nutrients from our food and environment.
