What is the purpose of radiopharmaceutical stability testing?

The purpose of radiopharmaceutical stability testing is fundamentally to ensure that the radiopharmaceuticals maintain their specified properties over their intended shelf life. This testing is crucial, as it validates that the efficacy, safety, and quality of the radiopharmaceutical remain intact throughout its duration of use. Stability testing assesses various factors, including chemical composition, radiochemical purity, and physical characteristics, which are essential for ensuring that the product remains effective and safe for clinical application.

Moreover, stability helps to prevent degradation or changes in the formulation that could lead to reduced therapeutic effectiveness or increased risks to patients. This aspect is vital, as radiopharmaceuticals are often time-sensitive products that require precise handling and storage conditions to preserve their integrity. Ensuring stability contributes to regulatory compliance and ultimately assures clinicians and patients of the reliability of the treatments being administered.
