Spending on Prescription Medications Increased About 5% in 2015

(HealthDay News) — Spending on prescription medications for insured Americans increased about 5% in 2015, with the increase half of that seen in 2014, the Associated Press reported.

According to Express Scripts Holding Co, the largest US prescription benefit manager, there was a 16.2% increase in the average price of brand-name drugs already on the market in 2015, with an increase of 98.2% since 2011. Price-increases exceeding 20% were reported for one-third of brand-name prescription drugs in 2015. Express Scripts forecasts that there will be a 6% to 8% increase in drug spending per year from 2016 to 2018.

The drug category with the most spending was for specialty medicines, specifically those medications for inflammatory conditions such as rheumatoid arthritis and psoriasis. Specialty drug spending increased 17.8%, including an average price increase of 11% and a 6.8% increase in the number of prescriptions filled for those drugs. Including factors such as patient copayments and manufacturer rebates, US medicine spending increased 5.2% in 2015, down from 10.1% in 2014.

“Spending increases in the second year of insurance exchange plans averaged 13.6%, much higher than for commercial insurance and Medicare and Medicaid prescription plans handled by Express Scripts,” according to the Associated Press. “That was mainly driven by an 8.6% increase in medicine use.”
