MonoSol Rx Granted US Patent for Thin Film Manufacturing Process

MonoSol Rx, a drug delivery company specializing in quick dissolving thin film pharmaceutical products, today announced that it has been granted U.S. patent No. 7,357,891 from the United States Patent and Trademark Office (USPTO). The patent, which is expected to issue on April 15, 2008, relates to the Company's proprietary mixing system technology and controlled film drying process.

"Granting of this patent is a significant milestone for MonoSol Rx as it validates and protects our thin film drug delivery technology. As we strive to expand the patent protection of our thin film technology, this milestone serves to fortify our leadership position in the delivery of prescription drugs using thin film" said A. Mark Schobel, president and chief executive officer of MonoSol Rx. "Our proprietary mixing and drying processes enable us to maintain precise content uniformity of the drug, incorporate taste-masked drug encapsulations, and allow the manufacture of sensitive drug targets that may otherwise not be possible. Each of these factors, combined with the convenience and dosing benefits of thin film, are key to the success of our technology, and help to differentiate MonoSol Rx from similar thin film offerings and other modes of drug delivery."

The patent relates to MonoSol Rx's Dual Integrated Mixing System. This patented mixing process is designed to provide a continuous batch coating of a drug contained in the film to ensure product uniformity while delivering consistent organoleptic performance throughout the film manufacturing process.

Also encompassed in the patent is MonoSol Rx's controlled film drying process. This controlled drying process is critical to maintaining content uniformity of a drug within the film thereby ensuring accurate and predictable dosing for patients.

Mr. Schobel also said, "This is an important acknowledgement of the innovative technology that MonoSol Rx has developed for thin film drug delivery. We are committed to pursuing and developing technology that provides significant advantages for MonoSol Rx and its development partners."
