Last year Big Pharma raised prices on 1,450 drugs as seen from linked article: https://www.fiercepharma.com/pharma/ira-inflation-price-caps-loom-pharma-kicks-2024-hundreds-price-hikes-report.

It is expected that it will be similar this year, with a range of 5% to 10% increases. Most prices are felt in the beginning of the year, with a second wave sometime mid-year. There are also many drugs that trickle up in prices during the year so that no shock is felt.
