This is yet another extended release product from the R&D pipeline of Wockhardt and the fourth such product to be approved by the US FDA in the yea, he added.
Citing figures from global information services and publishing firm Wolters Kluwer, Wockhardt said the total market for the drug in the US is about USD 214 million.
The tablets will be manufactured at the USFDA certified formulation plant at Waluj, Aurangabad and the Fexofenadine HCl active pharmaceutical ingredient will be manufactured in the FDA certified API plant at Ankleshwar, Gujarat, the company said.
