Cost & Quality Problems

Prescription Drug Costs

Prescription drug costs currently account for 15 percent of overall health spending and are once again coming under scrutiny as important drivers of healthcare spending.1

Spurred by blockbuster drugs like Lipitor and Plavix going off patent and increased use of generics, drug spending had moderated in the last decade since the high growth period of over decade ago.2 Three important trends are bringing this period of low drug spending growth to an end: increased spending on prescription drugs, the diminishing cost-saving  impact of generic drugs and price gouging by drug manufacturers. 

Brand Name Drugs

Retail prices for brand name prescription drugs increased by an average of 5.8 percent in 20183—more than double the inflation rate. Studies have also shown that price increases, not innovation, are driving prescription drug cost growth. A report published in Health Affairs found that more than 85 percent of the annual increases in the average weighted cost of brand-name drugs between 2008 and 2016 was attributable to existing drugs and less than 15 percent to new drug products.4 Additionally, pharmaceutical and biotechnology sales revenue increased from $534 billion to $775 billion between the same period, while the largest 25 companies maintained profit margins between 15 and 20 percent (more than double that of non-drug Fortune 500 companies).5 

High Cost of Specialty Drugs  

A form of brand name drugs, the term "specialty drug" does not have a uniform definition. The term broadly comprises drugs that are: high priced; often (but not always) made of biological matter; treat complex conditions; require special handling; or require infusion or injection in a doctor’s office.  

The cost of new speciaty drugs is truly prohibitive. In 2016, almost half of the drugs studied by America's Health Insurance Plans cost in excess of $100,000.6 Specialty drugs are used by fewer than 2 percent of privately insured patients in the United States but account for more than 46 percent of all drug spending.7 

Generics Becoming More Expensive

Evidence suggests that two generic competitors for a drug can lower the average generic price to nearly half that of the brand name product. Event more generic competitors can lower the average generic price to 20 percent of the price of the brand name product.8 

Unfortunately, high rates of generic substitution will continue but will do less and less to bring down overall spending. In coming years, fewer expensive brand name drugs are expected to go off patent.9 

A second reason generics are less likely to moderate future spending is that the costs of many generic drugs are increasing. The reason for these generic costs increases are complex and are due to many factors, from raw material shortages to generic competitors leaving the market. But whatever the reason, many drugs that have been historically inexpensive have seen sharp price increases. HCCI found that the average annual price growth for generic medications was 4 percent in 2016.10 However, some generic drug manufacturers, like Teva, Mylan and Novartis, have come under fire for inflating the prices of generic drugs as much as 1000 percent.11

Biosimilars

As more drugs take the form of biologics, the impact of generics is reduced. Biologics are made of biological matter and for that reason, cannot be replicated exactly. Instead, biosimilars can be introduced into the market. Biologics have a 12-year period of market "exclusivity," meaning that the U.S. Food & Drug Administration (FDA) cannot approve a biosimilar during this period. 

Impact on Consumers

These cost trends mean higher premiums for consumers, higher cost-sharing and sometimes even illegal, discriminatory formulary designs to deter enrollees who need expensive medicationsAnother market response to high costs is to limit patient choice. For example, the nation’s largest pharmacy benefits manager, CVS, negotiated an exclusive deal with and AbbVie Inc., a drug maker of an alternative to Sovaldi, in exchange for a discounted price.

Options for Curtailing Rx Costs

Options for curtailing high Rx costs include:

Federal

State

It will take a sustained effort by consumers, payers, purchasers working at both the state and federal level to make headway on these issues and ensure that healthcare costs are to be sustainable and access to life saving drugs is preserved.  In the short-run, advocates may want to consider getting involved in benefit design rules being discussed in state Marketplaces to try to mitigate the impact of high drug costs on sicker enrollees.
