Storage / Stability Studies of Drugs and Pharmaceutical Products
Shelf life refers to the period from initial preparation and packaging up to expiry date during which the drug dosage form continues to remain within its physical, chemical, and toxicological specifications at specified storage conditions. The product must retain the labeled claim  weel within the limit mentioned for speified products under drug act and related Pharmacopoeia.
As per USP; 4 types of stability studies:
Chemical, Physical, Microbiological, Toxicological
Factors affecting Stability
Environmental factors
Carbon dioxide
Other ingredients or excipients in the dosage form
Particle size of drug
pH of the vehicle
Microbial contamination
Trace metal Contamination
Leaching from containers
Condition of stability testing conduction
Shelf life storage stability
Accelerated conditions
Controlled room temperature conditions
Product samples are analyzed at various intervals by validated analytical methods
