That is what happens when you don't have patent exclusivity. I guess this is why "me-too" drugs come to market.
Express Scripts, one of the leading prescription-benefits managers in
the US, is partnering with a compounding pharmacy to provide a
$1-per-pill version of the drug that Turing Pharmaceuticals charges $750
The drug, which Turing sells under the name Daraprim, is used to treat toxoplasmosis, an infection that's harmful to people with weakened immune systems.
Scripts announced the partnership with Imprimis Pharmaceuticals on
Tuesday, and said prescriptions could be filled as soon as this week. In October, Imprimis said it would provide a customizable formulation to compete with Daraprim.
