Trends and determinants of retail prescription drug costs.

ABSTRACT:

Objective

To characterize price trends and variation for US generic and branded drugs at the retail level as they relate to pharmacy acquisition costs and local market factors.

Data sources

Drug pricing data consisting of US pharmacy claims from 2014 to 2019 collected and licensed by GoodRx, an online tool for comparing drug prices.

Study design

Time trends of median drug prices and coefficients of variation were measured for generic and branded drugs, including subgroups based on clinical condition (i.e., diabetes and cancer). Pharmacy competition was measured using the Herfindahl-Hirschman Index (HHI) at the zip-code level. Multivariable linear regression analysis assessed the impact of local market-level factors on drug prices and variation.
