The effects of alcohol (i.e., ethanol) on various tissues depend on its concentration in the blood (blood alcohol concentration [BAC]) over time. BAC is determined by how quickly alcohol is absorbed, distributed, metabolized, and excreted.
The ethanol contained in alcoholic beverages is rapidly absorbed from the gastrointestinal tract and the maximum blood-alcohol concentration (BAC) is usually reached between 10 and 60 min postdosing.
The daily energy requirement for a moderately active man is 3000 kcal and for a woman 2200 kcal. Absorption. Rate of absorption of alcohol depends on several factors. It is quickest, for example, when alcohol is drunk on an empty stomach and the concentration of alcohol is 20-30%.
LIST 2 describes some factors which affect the absorption of alcohol. Absorption of alcohol from the duodenum and jejunum is more rapid than from the stomach, hence the rate of gastric emptying is an important determinant of the rate of absorption of orally administered alcohol.
Of particular pertinence are the partition of alcohol between various body tissues and fluids and the resulting alcohol concentration ratios for blood: breath and other body fluids, as well as the irregularity and short-term fluctuations of the blood and breath alcohol curves.
The rate of alcohol absorption depends on the rate of gastric emptying and the concentration of alcohol, and is more rapid in the fasted state. The blood alcohol concentration is determined by the amount of alcohol consumed, the presence or absence of food, and the rate of alcohol metabolism.
