CARY, NC -- (Marketwire) -- 07/02/12 -- Cornerstone Therapeutics Inc. (NASDAQ: CRTX), a specialty pharmaceutical company focused on acquiring, developing and commercializing proprietary products for the hospital, and related specialty markets, today announced that the U.S. Food and Drug Administration (FDA) approved its Abbreviated New Drug Application (ANDA) for a generic Hydrocodone Polistirex and Chlorpheniramine Polistirex extended-release suspension product. The antitussive/antihistamine combination product is a generic equivalent for the product currently sold under the Tussionex® Pennkinetic® brand name. The product is indicated for the relief of cough and upper respiratory symptoms associated with allergy or a cold in adults and children six years of age and older.
CRTX 067 was developed through a collaboration including Cornerstone, Coating Place, Inc. and Neos Therapeutics, LP, a subsidiary of Neos Therapeutics, Inc. Cornerstone will market the product through its wholly-owned generics subsidiary, Aristos Pharmaceuticals, Inc. Coating Place manufactures and supplies the active pharmaceutical ingredients (APIs), including a patent-protected version of hydrocodone polistirex. Neos developed the CRTX 067 drug product formulation using its proprietary formulation technology, Dynamic Time Release Suspension® (DTRS®), and Neos will be the exclusive manufacturer of the approved drug product.
"We are pleased with the FDA's decision to approve our generic antitussive/antihistamine product," said Craig A. Collard, Cornerstone's Chief Executive Officer. "Given the recent industry challenges and changes related to prescription cough and cold medications, this product affords patients an approved generic drug product alternative as well as providing Cornerstone the opportunity for growth."
Collard added, "While Cornerstone recently completed its strategic shift away from primary care, one of our main goals through Aristos is to continue to seek out and introduce opportunistic generic products. The addition of a generic Tussionex to Aristos' product portfolio is yet another successful execution of this plan."
Cornerstone will begin manufacturing its generic antitussive/antihistamine product immediately. Despite competition from other generics, Cornerstone believes that there is a strong market opportunity given the demand that exists within this market. Antitussives are some of the most commonly prescribed medications during cough and cold season. Total prescriptions for Tussionex and related generics were 2.59 million in 2011 according to IMS Health, a third-party provider of prescription data. This represents a 2% increase in prescription volume as compared to 2010. Cornerstone management believes its distribution expertise will allow Cornerstone to effectively gain market share for its generic product.
Important Safety Information
Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension is contraindicated in children younger than 6 years of age due to the potential occurrence of respiratory depression that can lead to death, and in patients with a recognized allergy or sensitivity to hydrocodone or chlorpheniramine. Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension inhibits the cough reflex and may be associated with dose-related respiratory depression or irregular and periodic breathing. In the post-operative setting and in patients affected by pulmonary disease or depressed ventilatory function, caution should be used when Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension is administered. In case of head injury, other intracranial lesions, or a prior increase in intracranial pressure, narcotic-associated respiratory depression and increase in cerebrospinal fluid pressure may be significantly enhanced. Moreover, narcotics are associated with adverse reactions which may mask the clinical course of patients with head injuries. Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension is a Schedule III narcotic. Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension should be prescribed and used with caution due to the fact that repeated administration of narcotics is associated with psychic and physical dependence and tolerance. The administration of narcotics may mask the diagnosis of acute abdominal conditions and their clinical course. Obstructive bowel disease may result from the chronic use of narcotics, particularly in patients with intestinal motility disorders. In patients with narrow-angle glaucoma, asthma, or prostatic hypertrophy, caution is needed when prescribing this drug. Hydrocodone Polistirex and Chlorpheniramine Polistirex Extended-Release Suspension should be used with caution in elderly or debilitated patients and those with severe hepatic or renal dysfunction, hypothyroidism, Addison's disease, prostatic hypertrophy, or urethral stricture.
