ⓘ How this was built
Data sources
- CMS NADAC weekly survey + monthly archives back to 2013 (data.medicaid.gov)
- CMS Federal Upper Limit files (weighted AMP)
- FDA NDC Directory (openFDA) — maker roster
Method
Each month's band spans the NADAC unit prices of every NDC of this drug (min, quartiles, median, max), split into brand and generic cohorts by FDA marketing category. Maker counts come from distinct labelers with the NDC actively listed.

Same drug class
Other molecules FDA puts in Cytochrome P450 2D6 Inhibitor, with whether each is in shortage right now. Same class is not the same drug — substitution is a clinical decision, and this is a supply picture, not a recommendation.
