MUMBAI, May 15 (Reuters) - India's Supreme Court has blocked Glenmark Pharmaceuticals Ltd from selling copies of U.S. drugmaker Merck & Co Inc's diabetes drugs Januvia and Janumet, sources with knowledge of the matter said after a court hearing on Friday.
The court has, however, allowed Glenmark to continue to sell existing inventory, the sources said.
Merck sued Glenmark in 2013 for infringing a patent it has on sitagliptin, the chemical compound in Januvia and Janumet. Glenmark sells the medicines under the brand names Zita and Zita-met. (Reporting by Zeba Siddiqui and Nivedita Bhattacharjee in Mumbai)
