Acura Pharmaceuticals Provides Update on NEXAFED(R) Launch

Over 2,600 Pharmacies Now Selling the Meth-Resistant Pseudoephedrine Product

PALATINE, IL--(Marketwired - Sep 18, 2013) - Acura Pharmaceuticals, Inc. (NASDAQ: ACUR) today announced its next generation pseudoephedrine hydrochloride tablet, NEXAFED, is now being sold in over 2,600 pharmacies nationwide. Since its introduction in December 2012, NEXAFED has become the standard of care in many pharmacies, including all Fruth Pharmacies and all the independent pharmacies of Scott County, Tennessee, who stock NEXAFED as their only 30mg pseudoephedrine product. NEXAFED not only contains the unique methamphetamine-resistant IMPEDE® Technology but also meets a key Food and Drug Administration human clinical efficacy standard.

The recent increase in pharmacies stocking NEXAFED can be attributed to (i) Meijer Pharmacies who are stocking NEXAFED in all their pharmacies, (ii) the addition of a large regional supermarket chain based in Florida, and (iii) further distribution gains at independent pharmacies. Through national and regional wholesalers, Nexafed is readily available to nearly every pharmacy in the U.S.

"We're seeing a significant increase in repeat orders from pharmacies," said J. Bradley Rivet, Vice President, Marketing with Acura Pharmaceuticals. "We've come to appreciate that once pharmacists begin recommending NEXAFED and are satisfied with its effectiveness, they typically become an advocate."

"The launch of our current NEXAFED formulation continues to progress well as we prepare our improved IMPEDE 2.0 formulation for market," said Robert B. Jones, president and chief executive officer of Acura Pharmaceuticals. "The pharmacists and chain pharmacies that stock and recommend our product have reviewed our test results closely and been very discriminating in the selection of effective products they can recommend with confidence for their patients."

About NEXAFED®
NEXAFED® [pseudoephedrine hydrochloride] 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. 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 resist its isolation or purification.
