The absorption rate of ethanol is typically modeled as a first-order kinetic process depending on the concentration gradient and specific membrane. The rate of absorption is fastest in the duodenum and jejunum, owing to the larger absorption surface area provided by the villi and microvilli of the small intestines.

The absorption rate constant K a is a value used in pharmacokinetics to describe the rate at which a drug enters into the system. It is expressed in units of time −1. [1] The K a is related to the absorption half-life (t 1/2a) per the following equation: K a = ln(2) / t 1/2a. [1] K a values can typically only be found in research articles. [2]
It can be altered by behavior. Drinking large amounts of alcohol will reduce the biological half-life of water in the body. [8] [9] This has been used to decontaminate patients who are internally contaminated with tritiated water. The basis of this decontamination method is to increase the rate at which the water in the body is replaced with ...
The rate of elimination is fairly constant. Initially, the rate of absorption exceeds the rate of elimination, which results in a rising BAC. Sometime after a person stops drinking, the rate of absorption drops below the rate of elimination, and the BAC begins falling.
Instantaneous absorption: absorption is nearly immediate. A common example is bolus intravenous injection. Zero-order absorption: rate of absorption is constant. A common example is continuous intravenous infusion. First-order absorption: rate of absorption is proportional to the amount of drug remaining to be absorbed.
Binge drinking is defined as the amount of alcohol it takes to raise a person’s blood-alcohol concentration level to 0.08, the legal definition of being intoxicated in most states.
Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor. [9]Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and chloroform, demonstrating its ability to dissolve a wide range of substances including ethyl cellulose, polyvinyl butyral, oils, alkaloids, and natural ...
