Alcohol and antibiotics. Why are they not compatible?

What are the main risks of such a combination? There is a chance that alcohol will either destroy the active ingredient or cause it to bind to pathogens. Yes, and the process of excretion can act - slow down or speed up. In addition, alcohol and antibiotics are quite toxic, and their combination further depresses the liver. Antibiotics, for example, block the enzyme that breaks down alcohol - increasing the time of toxic exposure. So the ban on the use of alcohol during a course of antibiotics is justified.
