Study Notes
Drug Metabolism Overview
- Drugs entering the body are attacked by metabolic enzymes aiming to degrade or modify them for easier excretion.
- Metabolic reactions lead to the formation of metabolites, which can differ significantly in activity compared to the original drug.
Metabolites and Their Effects
- Common outcome: metabolites often lose the pharmacological activity of the parent drug.
- Possible scenarios:
- Some metabolites retain partial activity.
- In rare cases, metabolites exhibit greater activity than the original drug.
- Certain metabolites may produce different effects, potentially leading to side effects or toxicity.
Implications for Drug Development
- Understanding drug metabolism is crucial for medicinal chemists to avoid creating drugs that lead to harmful metabolites.
- The prodrug strategy utilizes metabolism to activate drugs once in the body, enhancing therapeutic effectiveness.
Regulatory Requirements
- Drug approval mandates comprehensive identification of all drug metabolites.
- Each metabolite's structure and stereochemistry must be determined.
- Assessment of the biological activity of metabolites is essential prior to approval.
