Dosage Regimen: Individualization

Dosage Regimen: Individualization

Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

Biological Effects of Radiation

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...

Dosage Regimen Designs: Nomograms and Tabulations

Dosage Regimen Designs: Nomograms and Tabulations

Nomograms and tabulations are vital tools used by clinicians to design accurate and individualized dosage regimens. These instruments provide a straightforward method for adjusting dosages based on individual patient characteristics, including age, weight, and physiological condition. The foundation of a drug's nomogram is population pharmacokinetic data collected and analyzed using specific models. This data simplifies complex equations, presenting them diagrammatically or tabularly for easy...

To identify areas for improvement in laboratory procedures and dose assessment.

Main Methods:

Voluntary participation of laboratories in an intercomparison programme.
Irradiations conducted according to ISO 4037-3 standards by accredited facilities (CRRD and ARN).
Data collection on laboratory practices, detector characteristics, and evaluation algorithms.

Main Results:

Performance evaluation based on ISO 14146 acceptance criteria.
Demonstration of the evolution of laboratory performance throughout the programme.
Identification of variations in laboratory capabilities and procedures.

Conclusions:

The intercomparison programme provides a benchmark for individual monitoring services in Argentina.
Continuous evaluation is essential for maintaining high standards in radiation dosimetry.
Findings will guide improvements in laboratory practices and regulatory oversight.
