Health Tech · Data Analytics
RxNav is a suite of free, publicly accessible REST APIs operated by the US National Library of Medicine (NLM), part of the National Institutes of Health (NIH). RxNav provides programmatic access to several authoritative drug databases: RxNorm (the standard drug naming vocabulary), RxTerms (simplified drug terms for clinical documentation), NDF-RT (drug classification and pharmacological properties), and RxClass (drug class relationships).

Different RxNav API use cases
- Nigerian Hospital Drug Interaction Checker:Integrate RxNav's drug interaction API into a Nigerian hospital's prescribing system or electronic health record (EHR) to flag potentially dangerous drug-drug interactions in real time when a doctor prescribes multiple medications to the same patient.
- Generic Drug Finder for Nigerian Pharmacies:Use RxNav's brand-to-generic mapping to build a tool for Nigerian pharmacies and patients that identifies affordable generic equivalents for expensive branded drugs helping patients access the same therapeutic benefit at lower cost.
- Drug Reference App for Nigerian Medical Students:Build a mobile drug reference app for Nigerian medical and pharmacy students using RxNav's drug information APIs providing mechanism of action, indications, contraindications, and drug class information for drugs they encounter in clinical training.
- Medication Reconciliation Tool for Nigerian Clinics:Use RxNav's RxNorm normalization API to standardize drug names across different systems in Nigerian clinics (where the same drug may be entered as brand name, generic name, or abbreviation), enabling accurate medication reconciliation across patient records.
