Oral Film Technology, VersaFilm™

IntelGenx immediate release oral film Technology, VersaFilm™, is made up of a strip of thin polymeric film comprised of United States Pharmacopeia (USP) components that are safe and approved by the FDA for use in food, pharmaceutical and cosmetic products. Derived from the edible film technology used for breath enhancement strips and initially developed for the instant delivery of savoury flavours to food substrates, the Instant Delivery Film has distinct advantages over existing fast dissolving oral tablets, which make it the application system of choice for indications requiring the immediate onset of action, like migraine, motion sickness, nausea, erectile dysfunction, or seasonal allergies.
