Study Notes
Biotransformation Purpose
- Primary purpose is to convert lipophilic substances into more water-soluble products, facilitating excretion from the body.
- Plays a crucial role in the metabolism of drugs, toxins, and endogenous compounds.
Key Organ for Biotransformation
- The liver is the most important organ for biotransformation, housing essential enzymes for metabolic processes.
Consequences on Drugs
- Drugs like phenobarbitone can be converted into more active forms or detoxified, affecting their efficacy and duration of action.
- Morphine undergoes biotransformation, which alters its pharmacological effects and may lead to active metabolites.
Location of Biotransformation Enzymes
- Biotransformation reactions are primarily catalyzed by enzymes located in the endoplasmic reticulum of liver cells, specifically cytochrome P450 enzymes.
Prodrugs in Biotransformation
- Prodrugs are inactive compounds that become active following biotransformation, allowing for targeted delivery and reduced side effects in the initial administration.
