Interchangeability Guidelines for Transdermal Delivery Systems: Regulatory Differences and the Case for Harmonization

Interchangeability guidances for transdermal systems need harmonization, as the next challenge to add uniformity and scientifical sense to the regulatory process. There are key differences among current guidances for interchangeability of transdermal systems, which could mean that a same clinical study is approved in one region and rejected in another one.

Clinical Studies for Generic Transdermal Patches: Bioequivalence, Adhesion, and Skin Safety Requirements

The clinical requirements for generic transdermal patch approval are substantially more demanding than those for conventional oral dosage forms. A generic tablet typically needs to demonstrate pharmacokinetic bioequivalence in a single crossover study. A generic patch requires bioequivalence under single and multiple dose schemes, statistical non-inferiority in adhesion performance, and [...]
