If so, the answer to your question is that Teva, like all of the CRAB manufacturers, charges as much
as it does
because it can. It's that simple.
They will tell you how
expensive it is to research new drugs, most of which never pan out, and they're right. They do need to recoup these costs, and they do need to make a profit or they'd be out of business, and then we'd all suffer.
However, and this is a BIG however, the CRAB drugs are huge profit-makers and have been for many years.
