Study Notes
- Drug metabolism is a process that involves the enzymatic conversion of drugs into metabolites, typically in the liver and intestines.
- The liver is one of the primary sites of drug metabolism.
- Drug metabolism is split into two phases: Phase 1 and Phase 2.
- Phase 1 metabolism is mediated by enzymes, particularly from the Cytochrome P450 (CYP) family.
- CYP enzymes metabolize over 60% of drugs on the market.
- Liver impairment, such as liver failure, can affect drug metabolism.
- Clearance is a term used in pharmacokinetics to describe the removal of drug from the liver.
- High clearance drugs, such as Alprenolol and Propranolol, are affected less by changes in blood flow.
- Low clearance drugs, such as Warfarin and Diazepam, are sensitive to changes in blood flow and plasma protein binding.
- Hepatic failure is a condition that can affect the handling of drugs by the liver, leading to changes in metabolism, distribution, and plasma concentrations.
- The Child-Pugh scoring system is used to make recommendations for individual drugs in the context of hepatic failure.
- The liver plays a crucial role in drug metabolism, and liver impairment can significantly affect drug clearance and pharmacokinetics.
