[Comprehension of the side effect profile of a new substance under development. Experimental toxicological aspects]
Abstract:
The detection of undesirable side effects takes place at several stages in the development of a drug. For this purpose all important endpoints such as acute toxicity, local tolerance, allergenicity, genotoxicity, subchronic/chronic toxicity and reproduction toxicity (male and female fertility, teratogenicity, peri- and postnatal studies) serve to establish the major toxicological characteristics. Comparative metabolism studies are carried out in order to optimize the extrapolation of the results obtained in animal experiments to humans. Special, non-routine studies must be adopted for testing cephalosporins and quinolones. Examples of these are provided.
Insights
Drug development involves detecting side effects through various toxicity tests. Metabolism studies optimize human extrapolation, with special tests for cephalosporins and quinolones.
Area of Science:
- Pharmacology and Toxicology
- Drug Safety Assessment
Context:
- Drug development requires rigorous safety evaluation.
- Identifying adverse effects is critical at multiple stages.
Purpose:
- To outline key toxicological endpoints for drug safety.
- To explain the role of metabolism studies in human extrapolation.
- To highlight specialized testing for certain drug classes.
Summary:
- Drug development employs diverse toxicological assessments including acute toxicity, local tolerance, allergenicity, genotoxicity, and chronic/reproduction toxicity.
- Comparative metabolism studies are crucial for extrapolating animal data to human subjects.
- Specific non-routine studies are necessary for evaluating cephalosporins and quinolones.
Impact:
