Acura Pharmaceuticals Awarded U.S. Patent for Abuse Deterrent Drug Formulations Further Expands Patent Estate Covering Abuse Deterrent Forms of Opioid Analgesics and Certain Other Active Pharmaceutical Ingredients PALATINE, IL -- (Marketwired) -- 04/04/13 -- Acura Pharmaceuticals, Inc. (NASDAQ: ACUR), a specialty pharmaceutical company innovating abuse deterrent drugs, today announced that the company has been issued U.S. Patent No. 8,409,616 by the United States Patent and Trademark Office. Claims in the patent cover, among other inventions, Acura's AVERSION polymer matrix technology when utilized with any water soluble drug of abuse. The opioid products being developed by Acura are covered by this patent. Also, certain claims in this patent are licensed to Pfizer Inc. (NYSE: PFE) which utilizes the AVERSION technology in its Oxecta(R) (oxycodone HC l) tablets CII. This is the fourth issued U.S. patent directed at products developed with the AVERSION technology. About Acura Pharmaceuticals Acura Pharmaceuticals is a specialty pharmaceutical company engaged in the research, development and commercialization of product candidates intended to address medication abuse and misuse, utilizing its proprietary AVERSION(R) and IMPEDE(TM) technologies. AVERSION contains polymers that cause the drug to gel when dissolved; it also contains compounds that irritate the nasal passages. IMPEDE is designed to disrupt the processing of pseudoephedrine from tablets into methamphetamine. In June 2011, the U.S. Food and Drug Administration approved OXECTA(R) (oxycodone HC1 tablets) which incorporates the AVERSION(R) technology. The Company has a development pipeline of additional AVERSION(R) technology products containing other opioids. In December 2012, the Company commenced commercialization of Nexafed(R) [pseudoephedrine hydrochloride (HCl)], a 30 mg immediate-release abuse-deterrent decongestant. The next generation pseudoephedrine tablet combines effective nasal congestion relief with IMPEDE(TM) technology, a unique polymer matrix that disrupts the conversion of pseudoephedrine into the dangerous drug, methamphetamine. The trademark OXECTA(R) is owned by Pfizer Inc.
