Bioral is a novel drug delivery system, based upon cochleate technology. Bioral encapsulates and protects a drug without chemically bonding to it and may facilitate oral dosing of drugs that typically need to be given by intravenous administration. Alternating layers of lipids spiral around a drug molecule, encapsulating it and potentially protecting it from degradation by acid or digestive enzymes in the stomach. The Bioral technology is being evaluated as a new means of overcoming the poor oral absorption of drugs, such as the antifungal drug Amphotericin B. Pre-clinical studies have demonstrated the potential value of agents delivered using the Bioral technology.1,2,3
The Bioral drug delivery technology was developed in collaboration with the University of Albany and the University of New Jersey Medical and Dental School, each of which has granted BDSI exclusive worldwide licenses under applicable patents.
