"The main takeaway of our study should be that increases in prices of brand-name drugs were largely driven by year-over-year price increases of drugs that were already in the market," CP3 Associate Director Inma Hernandez, PharmD, PhD, told NPR's Alison Kodjak. Kodjak reported on a recent study published in Health Affairs that examined drivers of drug price increases. In addition to their findings for brand-name drug price increases, Hernandez and her team determined that specialty and generic drug price increases were driven by new drug products.
