Prescription Drugs Introduced to Market

There are two types of New Drug data sets: Monthly and Annual. The Monthly data sets include the data in completed reports submitted by manufacturers for calendar year 2026, as of September 3, 2026. The Annual data sets include data in completed reports submitted by manufacturers for the specified year.

The data sets may include reports that do not meet the specified minimum thresholds for reporting. The program regulations are available here: hcai.ca.gov/wp-content/uploads/2024/03/CTRx-Regulations-Text.pdf The data format and file specifications are available here: hcai.ca.gov/wp-content/uploads/2024/03/Format-and-File-Specifications-version-2.0-ada.pdf DATA NOTES: Due to recent changes in Excel capabilities, it is not recommended that you save these files to .csv format.

If you do, when importing back into Excel the leading zeros in the NDC number column will be dropped. If you need to save it into a different format other than .xlsx it must be .txt Submitted reports that are still under review by HCAI are not included in these files. DATA UPDATES: Drug manufacturers may submit New Drug reports to HCAI for prescription drugs which were not initially reported when they were introduced to market.

CTRx staff update the posted datasets monthly for current year data and as needed for previous years. Please check the 'Data last updated' date on each dataset page to ensure you are viewing the most current data.
