It is well-known that competition in the generic manufacturer marketplace drives drug prices down considerably. Plaquenil, a brand-name drug that has been on the market since 1955, eventually saw generics enter the market almost a quarter of a century ago. By all accounts, generic Plaquenil – known as hydroxychloroquine – had become a very affordable drug at approximately 10 cents per pill. But FDA actions quickly dried up the supply of the drug, causing prices to balloon more than 2,500%. This report examines how state Medicaid programs were impacted by this price spike, and how some states continued paying elevated rates even after the price came crashing back down.
Of all the drugs in the marketplace, few have been as much of a topic of conversation as Gleevec, a popular medication for cancer patients. While the brand manufacturer Novartis was frequently criticized for its price increases during its exclusivity period, when the generics entered the market, prices of those versions plummeted. But in analyzing CMS data, we found that even though prices were crashing, some state Medicaid programs were still being charged much higher prices.
