PALATINE, IL, Dec 20 (Marketwire) -- 
Acura Pharmaceuticals, Inc. (NASDAQ: ACUR) today announced that an
Investigational New Drug application ("IND") has been filed with the U.S.
Food and Drug Administration (FDA) to allow clinical testing of Acura's
hydrocodone bitartrate with acetaminophen formulated with Aversion(R)
Technology. Clinical testing can commence under the IND 30 days following
the IND filing unless questions are raised by the FDA. An open IND is
required for Acura to initiate intranasal abuse liability testing in
recreational drug users of the crushed drug product.

    This study is part of a comprehensive development program we intend to
complete in anticipation of submitting a 505(b)(2) NDA for our
hydrocodone/acetaminophen product in the first half of 2014. The plan
also includes:

--  a pharmacokinetic study demonstrating dose proportionality and
    evaluating the food effect;
--  a battery of laboratory studies demonstrating extraction, syringing
    and particle size characteristics;
--  a pharmacokinetic study to establish a bridge to a new contract
    manufacturer; and
--  an assessment of the routes of abuse of hydrocodone products.


Acura continues to evaluate possible partnering of our Aversion
development products with alternative strategic partners. 

    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)

    In June 2011, the U.S. Food and Drug Administration approved OXECTA(R)
which incorporates the AVERSION(R) technology. The Company has a
development pipeline of additional AVERSION(R) technology products
including 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.
