| Acronym | DRON |
| Visibility | Public |
| Description | We built this ontology primarily to support comparative effectiveness researchers studying claims data. They need to be able to query U.S. National Drug Codes (NDCs) by ingredient, mechanism of action (beta-adrenergic blockade), physiological effect (diuresis), and therapeutic intent (anti-hypertensive). |
