Understanding Photostability Studies for Pharmaceuticals Photostability studies are essential for assessing how pharmaceutical products degrade when exposed to light. Light exposure can trigger various degradation pathways, leading to changes in the drug’s chemical composition, potency, and stability. Conducting comprehensive photostability studies helps ensure that pharmaceutical products remain safe and effective when stored and used under…
Ensuring Safety and Efficacy: Stability Considerations for Pediatric Drug Formulations Pediatric drug formulations require careful consideration to ensure that they remain stable, safe, and effective for children. Due to the unique physiological and developmental characteristics of pediatric patients, these formulations often involve specific requirements that differ from those for adult medications. Stability studies for pediatric…
Impact of Manufacturing Process Changes on Stability Studies Stability studies are essential for ensuring that pharmaceutical products maintain their quality, safety, and efficacy throughout their shelf life. When changes are made to the manufacturing process, it can significantly impact the stability profile of both drug substances and drug products. This necessitates a careful re-evaluation through…
