How to Maximize Shelf Life of Topical Formulations

Topical formulations as drug delivery systems are becoming increasingly popular. The shelf life, or period of time before the expiration date, is determined by the stability of the delivery system containing the drug. To create an effective and long-lasting topical formulation, the initial suspension that contains the actual drug must be stable. This white paper discusses how to maximize shelf life stability of suspensions through zeta potential analysis.
