A massive lawsuit filed in May by 44 states accuses 20 major drug makers of colluding for years to inflate prices on more than 100 generic drugs, including those to treat H.I.V., cancer and depression. If true, the alleged behavior is not just a violation of antitrust law, but also a betrayal of the government policies that created and defended the entire generic drug industry.
Most prescriptions in the U.S. today — 9 in 10 — are filled with generics, which are just as safe and effective as their brand-name equivalent. And yet generics account for only 22 percent of U.S. prescription drug spending. These prices are so low because of competition between makers of different versions of the same generic drug. The more competing generic alternatives, the lower the price, theoretically right down to the marginal cost of manufacturing the pill.
This success is the result of decades of careful federal and state policymaking, all geared towards introducing competition in prescription drug markets. The entire generic industry has its origins in the Hatch-Waxman Act of 1984. Prior to Hatch-Waxman, a company that wanted to sell a competing version of a drug whose patents had expired had to conduct lengthy and expensive clinical trials to get approval from the U.S. Food and Drug Administration. Hatch-Waxman established a quicker, less-expensive path to FDA approval that leans on the scientific research supporting the already approved brand-name drugs.
Hatch-Waxman also created incentives for generic drug makers to challenge drug patents that prevent competition. Successful challengers win a 180-day period of exclusivity during which their generic is the only one allowed to compete with the brand-name drug. The floodgates open and additional competition pushes prices down further after the 180-day period.
