PISGAH FOREST, N.C., March 25 /PRNewswire/ -- Pisgah Labs, a drug product development company and an active pharmaceutical ingredient manufacturer (API) located in western North Carolina, has received a patent allowance in a series of patent applications. The US Patent & Trademark Office (USPTO) has notified Pisgah Labs, Inc. (http://www.pisgahlabs.com) that a patent application related to a therapeutically significant family of pharmaceutical polymorphic compositions of imipramine pamoate has been allowed. The patent application also includes methods of manufacturing, purifying and use in pharmaceutical preparations.
In regard to imipramine pamoate, used in the well-known product Tofranil PM(R), some may say activity level required was disproportionate to the achievement. “Not so,” says Pisgah’s president, Bill Bristol. “From what we learned while focused on this imipramine we have leveraged this knowledge into a new business opportunity for the Company. Our discoveries led to additional patent filings related to abuse-deterrent prescription drugs like oxycodone and hydrocodone. We realized we could apply our findings to pain products to achieve selective dissolution profiles. From our early work with imipramine, we’re now heavily engaged in developing abuse-deterrent forms of narcotics including hydrocodone - the most abused drug in America.”
Pisgah anticipates additional patent allowances soon supporting its commercial (imipramine) efforts and the broader foray into abuse-deterrent products. To learn more about these opportunities and Pisgah’s technology licensing program, visit http://www.pisgahlabs.com
