Drug Prices Haven’t Been Going Up

The myth that they have drives Biden’s proposals for price controls, which would throttle innovation.

"As the consumer-price index over the past year rose 6.8%, the largest increase in 39 years, prescription-drug prices fell 0.3%."

"Mr. Biden and other pharmaceutical critics have mistakenly focused on increases in the list prices set by companies. But the actual prices consumers pay, after various discounts and rebates, are considerably lower than list prices, and changes in the two measures differ substantially. Insulin, with large increases in list prices over the past few decades, has become the poster child for unreasonable price increases. Yet net prices have increased much more slowly or not at all.

The best measure is the consumer-price index for prescription drugs, or CPI-Rx, which measures price changes in a large basket of drugs over time, accounting for discounts and most rebates. Another strength of the CPI-Rx is that it accounts for price declines that occur when consumers substitute cheaper generic versions for brand-name drugs. Too often, Mr. Biden and others focus on a few high-priced drugs and fail to consider the entire market.

Prices for brand-name prescription drugs are higher in the U.S. than in other countries. But U.S. regulatory, legal and incentive structures encourage aggressive price competition and switching from branded drugs to generics. As a result, Americans use more generics (accounting for 9 out of 10 prescriptions) and pay less for them (16% lower on average) than in other developed countries. Nearly all European countries impose price controls on generics, which results in delayed market entry and availability, less competition and higher prices.

CPI-Rx has been negative for much of the past three years. The decline stems largely from increased drug approvals by the Food and Drug Administration since 2017. When new brand-name drugs enter the market, they compete with other drugs that treat the same condition. When generic versions are approved, prices fall rapidly as patients switch, especially as multiple generic versions enter the market.

An analysis of per-unit prices of 27 types of insulin by GoodRx, a healthcare company that tracks drug prices and provides discount coupons, found that overall retail prices declined by nearly 6% since 2019 because of recent approvals of generics and biosimilar drugs."
