Ophthalmic microemulsion drugs such as Restasis, indicated for dry eye syndrome, are speciality pharmaceuticals, and are considered complex generics because of their route of delivery and localized activity. Complex generics are challenging to produce, particularly so when it comes to proving bioequivalence with the corresponding Reference Listed Drug.
This webinar aims to provide a guide for proper physical characterization of microemulsions, specifically considering some of the issues with the complexity of such formulations.
