  • Title: [Liver and drug metabolism].
    Author: Mikheeva OM.
    Journal: Eksp Klin Gastroenterol; 2011; (2):121-4. PubMed ID: 21560652.
    Abstract:
    Liver metabolism aims to change the biological activity of drugs to make them water-soluble to be excreted with bile and urine. The degree of metabolism depends on fermentative capacity for each drag (P450 fermentative system is localized in microsomal fraction of hepatocyte). Metabolism ability also changes under the influence of other substances. Liver diseases lead up to decrease of drug clirens and to increase the semi-excretion time because of reduction of liver metabolism. Therefore the drags usually undergoing intensive liver metabolism necessitate a high risk of overdose when liver diseases present. On the other hand no risk of overdose exist when drags with low liver metabolism are used.
