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 their therapeutic effectiveness, ensuring that patients receive the intended treatment benefits.
- Ensuring Safety: Stability testing helps identify potential degradation products or harmful changes in drug composition, ensuring the safety of patients.
- Regulatory Compliance: Regulatory authorities require pharmaceutical companies to demonstrate the stability of their products to obtain approval and ensure compliance
with quality standards.
Quality Assurance: Drug stability testing is integral to quality control processes, ensuring that products meet established quality standards and specifications.
Cost-effectiveness: Stability studies help optimize packaging, storage conditions, and shelf-life, minimizing product wastage and associated costs.
Customer Satisfaction: Stable drugs with reliable potency and 
quality enhance patient confidence and satisfaction with the pharmaceutical products.
