PALATINE, IL--(Marketwire - December 10, 2012) - Acura Pharmaceuticals, Inc. (NASDAQ: ACUR) today announced the launch of Nexafed® [pseudoephedrine hydrochloride (HCl)], a 30 mg immediate-release next generation pseudoephedrine product, combining effective nasal-congestion relief with a unique technology that disrupts the conversion of pseudoephedrine into the dangerous drug, methamphetamine. Nexafed® is now available to national and regional drug wholesalers and will be available to pharmacies soon. This is the second of two products to reach the market that utilize Acura's abuse-deterrent technologies.

"The launch of Nexafed® is a significant milestone for Acura and in the continued fight against meth in the U.S.," said Robert B. Jones, president and chief executive officer of Acura Pharmaceuticals. "Acura is highly committed to addressing the needs of local communities by investing in the development of abuse-deterrent technologies and medicines. It's not about innovating once, but continuing to improve on the technology without compromising efficacy."

Nexafed® delivers the same efficacy as leading pseudoephedrine products. In a clinical study Nexafed® was shown to meet the Food and Drug Administration's (FDA) guidelines for bioequivalence when compared to the leading national brand product.(1) For consumers, confirmation of bioequivalence provides assurance that Nexafed® delivers the same cold and allergy relief they have come to rely on -- but with the added benefit of disrupting possible methamphetamine production.

Pseudoephedrine, a decongestant used in some cold and allergy medicines, is the primary ingredient converted during illegal methamphetamine production. Unlike other cold and allergy pseudoephedrine products, Nexafed® is the only medicine that utilizes Acura's Impede™ technology, a unique polymer matrix that disrupts the extraction and conversion of pseudoephedrine to methamphetamine. If abusers try to extract the pseudoephedrine out of Nexafed® to make methamphetamine, the inactive ingredients in the polymer matrix will form a thick gel to block that extraction and disrupt conversion of pseudoephedrine to methamphetamine.

Laboratory tests conducted on Acura's behalf by an independent research organization demonstrated that in the two methods of methamphetamine production that require pseudoephedrine extraction prior to conversion, no pseudoephedrine could be extracted and isolated from Nexafed® using a range of aqueous and organic solvents. In addition, in the direct conversion method, or "one-pot" technique used in home labs, laboratory tests demonstrated that Impede™ technology reduced the yield of methamphetamine from conversion of pseudoephedrine by about half of that derived from the leading national brand product.

"The introduction of cold and allergy products with abuse-deterrent technologies is a significant step forward for communities across the country affected by the debilitating effects of meth production," said Priscilla Lisicich, executive director of Safe St. located in Tacoma, Washington and former co-chair of the National Methamphetamine Training and Technical Assistance Center. "A medicine that deters meth production without compromising efficacy will ensure people have access to the medicines that they need."

Methamphetamine production and abuse is a serious problem that has become increasingly common in communities across the U.S. In 2011, approximately 439,000 Americans ages 12 years and older had abused methamphetamine.(2) The impact of methamphetamine extends beyond those who use and abuse the drug. Methamphetamine production creates increased danger in communities from fire, explosions, exposure to toxic chemicals and crime.

Last year, more than 10,000 clandestine labs were found in the U.S., triggering environmental hazards and requiring expensive and timely cleanup by local governments.(3) In addition to environmental hazards, the economic cost of methamphetamine use in the U.S. -- estimated at $23.4 billion in 2005 -- is staggering, accounting for the burden of addiction and drug treatment.(4)

"We hope the availability of Nexafed® empowers pharmacists to impact meth abuse at a local level by stocking and recommending the product," said Jones. In a recent market research study, 70 percent of chain and independent pharmacists involved in pharmacy stocking decisions said they were likely to stock or recommend stocking Nexafed® in their pharmacies. These pharmacists further indicated a willingness to recommend Nexafed® to over 50 percent of their customers who seek a pharmacist's advice in need of a single ingredient nasal decongestant like Nexafed®.

Nexafed® is now available to national and regional drug wholesalers and will be available to pharmacies soon. Acura has priced Nexafed® comparably to name-brand pseudoephedrine products. For more information about Nexafed®, please visit JOIN-FIGHT.COM.

About Nexafed®
Nexafed® [pseudoephedrine hydrochloride (HCl)] is a 30 mg immediate-release abuse-deterrent decongestant. The next generation pseudoephedrine tablet combines effective nasal-congestion relief with Impede™ technology, a unique polymer matrix that disrupts the conversion of pseudoephedrine into the dangerous drug, methamphetamine. Specifically, the Impede(™) technology forms a thick gel when the tablets are dissolved in solvents typically used in the pseudoephedrine extraction or methamphetamine production processes, trapping the pseudoephedrine or converted methamphetamine to prevent its isolation or purification.
