Definition of Expiration date
Expiration date: The date for a drug estimated for its shelf life with proper storage in sealed containers away from harmful and variable factors like heat and humidity.
The expiration date of a medicine is based on data, called accelerated stability data, from testing by the manufacturer, that show the product will be good for a particular period of time.Source: MedTerms™ Medical Dictionary
