PALATINE, IL--(Marketwire - Nov 20, 2012) -  Acura Pharmaceuticals, Inc. (NASDAQ: ACUR), a specialty pharmaceutical company developing products intended to address medication abuse and misuse, announced today topline results from a clinical study that demonstrates Acura's NEXAFED (pseudoephedrine hydrochloride) is bioequivalent to the leading national brand product. The study was a Phase 1 pharmacokinetic study in 30 healthy adult subjects to confirm that changes made to the formulation for NEXAFED to improve manufacturability in support of a national launch will continue to provide effective relief of nasal congestion expected by pharmacists and consumers.

NEXAFED is a 30 mg immediate-release next generation pseudoephedrine tablet, which combines effective nasal-congestion relief with Acura's unique IMPEDE technology that disrupts the conversion of pseudoephedrine into the dangerous drug, methamphetamine.

"It is important that our IMPEDE technology used in NEXAFED does not compromise the effectiveness of the active ingredient, and the results of our clinical study demonstrate this," said Bob Jones, President and Chief Executive Officer of Acura Pharmaceuticals. "We remain on track for a national launch of NEXAFED later this year."
