So in fact, this drug could be cheaper than the Mylan version, but it looks like they never dug in deeper to find out if it's true.
Second of all, the first generic approved gets 180 days of market exclusivity whereby the FDA will not approve any other generic versions. This is such that the generic manufacturer can recoup the investment prior to widespread competition that drives down prices.
For example, Lipitor went generic and the price dropped only ~10-20%. After the 180 days, multiple generic companies got approval and now the price is 80-90% lower.
