The drug products applied topically may exhibit either local or systemic effects. Though transdermal patches are emerging mode of drug delivery system and offer several advantages over conventional modes of drug delivery; choosing a drug candidate that is suitable for making transdermal formulations can be a complicated task. Further, a lot of variables affect the bioavailability of drug as it passes through various layers of skin. This necessitates that TDS patches as well as topical products must be evaluated for several parameters such as bioavailability, biocompatibility, adhesion, intended efficacy, and many more.
At VIMTA, we offer testing of topical products as well as TDS patches. Our studies are based on Maximum Usage Trial standard approach for FDA submissions of Over The Counter products. In addition we also offer skin irritation, skin sensitization and adhesion studies for TDS patches.
