Pharma Stability: Insights, Guidelines, and Expertise
Definition of Drug Stability Drug stability refers to the ability of a pharmaceutical product to maintain its chemical, physical, and microbiological properties within acceptable limits throughout its shelf-life or specified storage period. Importance of Drug Stability Understanding and ensuring drug stability is crucial for several reasons: Maintaining Efficacy: Stable drugs are more likely to retain…
Goals of Stability Studies The primary goals of stability studies in pharmaceutical development are: Assessing Shelf-Life: Determining the period during which a drug product maintains its intended quality, potency, and safety under defined storage conditions. Evaluating Product Quality: Monitoring changes in the chemical, physical, and microbiological attributes of a drug over time to ensure compliance…
Introduction to Regulatory Oversight Regulatory agencies such as the U.S. Food and Drug Administration (FDA), European Medicines Agency (EMA), and International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) play a crucial role in establishing standards and guidelines for stability studies in the pharmaceutical industry. Key Regulatory Requirements and Guidelines Let’s…
