Total spending on medicines in the U.S. reached $310 billion in 2015 on an estimated net price basis, up 8.5 percent from the previous year, according to a new report issued today by the IMS Institute for Healthcare Informatics.
Spending on specialty medicines has nearly doubled in the past five years, contributing more than two-thirds of overall medicine spending growth between 2010 and 2015. Overall, 2015 saw a 21.5 percent spending increase for specialty medicines to $150.8 billion on an invoice price basis. Nearly 250,000 new patients received treatment for hepatitis C in 2015 , a 46% increase from 2014. But "patient new therapy starts peaked in March 2015 and have started to slow as the bulk of warehoused patients have sought and received treatment," notes the report.
