Summary
Alternative specimens like hair and saliva offer non-invasive, cost-effective doping control. While effective for some substances, saliva and hair analysis have limitations for time-sensitive or dose-dependent drug prohibitions.
Area of Science:
- Forensic toxicology
- Doping control
- Analytical chemistry
Background:
- Alternative specimens (hair, saliva) are established in forensic toxicology.
- They offer non-invasive, cost-effective, and long-term retrospective benefits compared to blood.
- This study explores their application and limitations in sports doping control.
Purpose of the Study:
- To evaluate the utility of alternative specimens in doping control.
- To identify compounds and scenarios where these specimens are advantageous or limited.
- To explore novel applications in monitoring drug use in sports.
Main Methods:
- Review of existing methodologies for analyzing alternative specimens.
- Comparison of detection capabilities for various prohibited substances.
- Assessment of limitations regarding time-frames, dosages, and administration routes.
Main Results:
- Certain prohibited substances (e.g., clenbuterol, β(2) agonists) are detectable and interpretable in alternative specimens.
- Saliva can differentiate time-sensitive prohibitions (e.g., in-competition stimulants) and administration routes.
- Quantitative saliva analysis may prove exogenous testosterone administration; hair analysis offers retrospective monitoring of social/unapproved drugs.
Conclusions:
- Alternative specimens are valuable tools in doping control, complementing blood analysis.
- Saliva and hair analysis offer distinct advantages for specific doping scenarios.
- Further research into quantitative methods and novel applications is warranted.

01:19Pharmaceutical Alternatives: Excipients and Impurities-Related Therapeutic Nonequivalence
Pharmaceutical products contain more than just the active drug; they also contain various excipients such as binders, solubilizers, stabilizers, preservatives, and other elements. In some cases, impurities or contaminants might be present. Traditionally, quality control in pharmaceuticals has primarily focused on the analysis of the active drug, often overlooking the impact of these additional components. The recent issue with heparin contamination by over-sulfated chondroitin sulfate, a...
01:27Pharmaceutical Alternatives: Polymorphic Form-Related and Particle Size-Related Therapeutic Nonequivalence
Changes in polymorphic forms can significantly influence the bioavailability of poorly soluble drugs. Although the FDA defines pharmaceutical equivalence based on having the same active ingredient, dosage form, and route of administration, it does not automatically disqualify products with different polymorphic forms. This means two products with different polymorphs can still be deemed pharmaceutically equivalent. However, polymorphic differences can affect properties like wettability,...
