A few decades ago, chewing gum was rarely considered when industry searched for an applicable delivery vehicle for an active pharmaceutical substance. Yet, the 1980s and 1990s saw gum become the most successful nicotine delivery form; unawareness changed to cautious scepticism, and today the merits of chewing gum drug delivery technologies are generally appreciated. MediChew is the registered trademark of Fertin Pharma's medical chewing gum technology platform. Based on patent-protected technologies, it offers unique taste-masking possibilities and allows control of drug molecule release. Medical chewing gum products based on these technologies are specifically suitable for convenient administration on demand, for active substances providing a topical effect in the oral cavity and throat, and for systemic delivery of drug molecules that readily cross the oromucosal membranes.
