Overview

Price and approval history for every US drug product, linked at NDC level so it joins cleanly with claims and formulary data.

What's included

  • Wholesale acquisition cost (WAC) per unit with effective dates and percentage change for each price move
  • National Average Drug Acquisition Cost (NADAC) per unit, weekly
  • FDA approval type and date, application number and Orange Book therapeutic equivalence codes
  • Product attributes: active ingredient, strength, dosage form, route, package size and manufacturer
  • Launch, discontinuation and generic-entry events

How buyers use it

  • Tracking list price increases by manufacturer and therapeutic class
  • Forecasting generic and biosimilar erosion after loss of exclusivity
  • Benchmarking acquisition costs in pharmacy and payer analytics
  • Supporting market-access and pricing strategy for new launches

Coverage and methodology

List price changes are compiled from manufacturer price notices and state drug price transparency filings, and checked against prior values; any change above 10% is reviewed by an analyst. NADAC comes from the weekly CMS files. Approvals and equivalence codes come from Drugs@FDA and the Orange Book. Everything is linked at 11-digit NDC level and rolled up to product and ingredient. Prices are list and survey-based acquisition costs, not net prices after rebates. History runs from 2013 and updates weekly.

    Claims aggregates work well for market sizing

    Procedure volumes by region gave us a defensible market size for a new device. Small cells are suppressed, so rare procedures in small regions come back empty, which is the correct trade-off for de-identified data.

    Affiliation data is the strongest part

    Provider-to-hospital and group-practice affiliations were more current than our previous source, which improved territory alignment. Price is at the high end, so we licensed the national file without the API.
