"So if the Lupenox product sold in India and made by Italfarmo has been altered at some point since approval in India [to become the product Teva (re)submited to the FDA], then that change would have to be approved by Indian regulators- but would that approved change be publicized?

Good luck to anyone who makes the attempt. You'll need more time and patience than I've got. Frankly, I don't think there's much there.
All the hot IT professionals in India must be working for private enterprises.
