When a patent expires it means there's no longer a monopoly. Now I gather there are like 20 or something companies that offer Paxil.. that aren't called Paxil and or are very slightly modified. like it matters
But ...but.....but...what about the conspiracy theories?!?!?!?!?! How dare you use logic.
