I think they will release the news to pump the price but at the end of the day, FDA "approval" of a generic menthol/lidocaine pain cream is nothing special.
The approval constitutes it already being an approved mixture of FDA approved ingredients with the approval focusing more on labeling and claims made on packaging.
This will not result in any significant sales as I doubt we will be seeing this product on the shelves of Walgreens or anything, it will be sold on Amazon
