Tris Pharma, a specialty pharmaceutical company that develops innovative drug delivery technologies, announced the launch of Tris-labeled generic TUSSIONEX®, an extended-release suspension containing hydrocodone polistirex and chlorpheniramine polistirex.
Tussionex®, originally approved in the early 1980's, had no generic competition until 2010 when Tris Pharma's generic product entered the market under an exclusive distribution agreement with Par Pharmaceuticals. Under the terms of the distribution agreement, Par had the exclusive right to market Tris Pharma's hydrocodone polistirex and chlorpheniramine polistirex ER oral suspension for a five year period ending September 30, 2015. With the conclusion of the five year term, the rights have reverted back to Tris and as of October 1, 2015, hydrocodone polistirex and chlorpheniramine polistirex ER Suspension in 115ml and 473 ml bottles (compare to Tussionex®) will be marketed and distributed by Tris Pharma's generic business.
