  "rxcui1": "11289",
  "rxcui2": "1191",
  "severity": "major",

Use Cases

1. Polypharmacy Screening

A geriatric ward pharmacist inputs a patient's 8-drug regimen and instantly receives all 28 pairwise interaction flags — prioritising review of contraindicated and major pairs before medication reconciliation.

2. Medical Education Tool

A medical school integrates the actor into a teaching platform where students enter drug combinations and receive FDA-sourced interaction data for case-based learning exercises.

3. Clinical Decision Support Pipeline

A telehealth startup calls this actor as a microservice when a prescriber adds a new drug to a patient record — results feed a risk flag system that triggers pharmacist review for high-severity interactions.

Data Sources

RxNorm CUI: NLM RxNav API — drug name normalization
Interaction data: OpenFDA Drug Label API — official FDA prescribing information

Pricing

Pay-per-result. Checking 5 drugs = 10 pairs ≈ $0.05–$0.10.
