Tris Pharma launches its Tussionex generic

MONMOUTH JUNCTION, N.J. — Specialty pharmaceutical company Tris Pharma on Thursday announced that it had launched its generic version of Tussionex (hydrocodone polistirex and chlorpheniramine) extended-release suspension. 

 

The drug is indicated to treat cough and upper respiratory symptoms of allergies and colds, and will be available in 115- and 473-ml bottles.

 

Tris’ suspension uses its LiquiXR technology, which uses an aqueous base coating system to avoid toxic organic solvents. The generic will be marketed and distributed by the company’s generic business following the expiration of a distribution agreement with Par Pharmaceuticals, who had the rights to it starting in 2010.
