Shelf Life / Stability Studies of Drugs and Pharmaceutical Products
What is Shelf life in case of Health Care Products ?
Shelf-life refers to the period from initial preparation and packaging during which the drug dosage form continues to remain within its physical, chemical, therapeutic and toxicological specifications at specified storage conditions.
The product must retain 90% of the labeled claim at the end of shelf-life.
What does stability mean for drugs and pharmaceuticals ?
The stability of the product is its ability to resist deterioration. It is always expressed in terms of shelf life.
As per USP there are five types of stability studies :
✿ Chemical
✿ Physical
✿ Microbiological
✿ Therapeutic
✿ Toxicological
What are the factors affecting Stability ?
The various factors affecting pesticides stability are :
- ▶ Environmental factors
- ▶ Temperature
- ▶ Light
- ▶ Air
- ▶ Oxygen
- ▶ Moisture
- ▶ Carbondioxide
- ▶ Other ingredients or excipients in the dosage form
- ▶ Particle size of drug
- ▶ PH of the vehicle
- ▶ Microbial contamination
- ▶ Tracemetal Contamination
- ▶ Leaching from containers
