WebBiotransformation performs the following functions: 1. It causes conversion of an active compound to a less active compound, which is called inactivation or detoxification. Examples are phenobarbitone to p-hydroxyphenobarbitone and DDT to metabolite products DDE and DDA. 2. WebAug 20, 2012 · Furthermore, the activity and capacity of hepatic drug metabolizing enzymes might be affected to various degrees in patients with chronic liver disease. These changes would result in increased concentrations and reduced plasma clearance of drugs, which is often difficult to predict. The pharmacology of analgesics is also altered in liver disease.
WebDec 12, 2024 · Biotransformation is an important reason for this variable. Some CP congeners are readily biodegradable in plants, animals, and microorganisms. Hydroxylation, dechlorination, chlorine rearrangement, and carbon chain decomposition are potential biotransformation pathways for the CP congeners. WebHepatic drug transporters are present throughout parenchymal liver cells and affect a drug’s liver disposition, metabolism, and elimination (for review, see [ 1, 2 ]). The 2 primary types of transporters are influx, which translocate molecules into the liver, and efflux, which mediate excretion of drugs into the blood or bile.
