In 2022, drugmakers raised prices on more than 1,400 drugs according to data published by 46brooklyn, a drug pricing non-profit that is related to 3 Axis.
The median drug price increase was 4.9% last year, while the average increase was 6.4%, according to 46brooklyn.
Antonio Ciaccia, president of 3 Axis, said that drugmakers have focused on launching their drugs at higher prices because of the attention paid to annual price increases.
More drug prices are likely to be announced over the course of January - historically the biggest month for drugmakers to raise prices.
Sanofi plans to raise prices on 14 of its drugs or vaccines.
