Commenting on the judgment, Amit Patel, head North America Generics, Dr Reddy's, said, "We are very pleased with the favourable summary judgment ruling in the Omeprazole Mg OTC litigation. This is a key event supporting our strategy to deliver one upside opportunity every year. We have submitted our ANDA filing and are awaiting FDA response. At this point in time, we will continue to work through the regulatory approval process while simultaneously progressing manufacturing and commercialization preparation."
