The finding means that many pricy, brand-name drugs are not facing the competition that could help drive down soaring prices. Among the drugs missing in action are generic versions of the expensive blood thinner Brilinta and the HIV medication Truvada. Moreover, of the approved drugs that would offer a brand-name drug its first competition, 36 percent are being held off the market, the analysis found.
Experts told KHN that the reasons drug makers may withhold an approved generic from the market are varied. Industry consolidation has made buying, manufacturing, and distributing generics more difficult in recent years. Generic drug makers also, as always, face patent litigation from brand-name makers. Then there’s potentially anti-competitive deals, in which brand-name drug makers simply pay generic makers to keep their product off the market for a while—a so-called “pay for delay” tactic.
