PharmaDirections has added another issued patent to their list of patents where they helped invent new technology for their clients. This one is United States Patent 8,318,788 which has been issued for “Layered Pharmaceutical Formulations”. This was a second patent that was a result of a collaborative formulation development effort between the scientists at Orexigen, PharmaDirections and their sub-contractors.
The technology is for multiple layered pharmaceutical formulations for drug products such as Contrave®, a treatment for obesity. The patent is assigned to Orexigen Therapeutics, Inc. who currently has an NDA for Contrave® under review at the FDA. In the example of an oral, controlled release dosage formulation, the middle layer is inert and dissolves in vivo to leave two separated drug containing layers intact until dissolution begins. This was done to separate potentially interacting layers from one another within the tablet and to allow each pharmaceutical layer to have its own controlled release dissolution profile. The pharmacokinetic modeling and formulation design was done at PharmaDirections.
"Our collaborative effort with Orexigen resulted in multiple accomplishments including this issued patent and the submission of 4 other patent submissions,” said Dr. Richard Soltero, President of PharmaDirections. “This brings us to 21 issued and issued patents for our clients where a PharmaDirections staff member was one of the inventors. We have helped a lot pharmaceutical companies find additional intellectual property by solving problems of bioavailability, stability or off-label competition.”
