How this service works
Resolves two products to their RxNorm concepts and compares what the register declares about each: the active ingredient set, the strength per ingredient, the dose form and the route of administration. Every difference is listed individually rather than collapsed into a verdict, and matching ingredients with differing strengths are reported as such rather than as a match.
Output
A structured comparison of the two resolved drug products showing: matched and unmatched active ingredients, per-ingredient strength values with any discrepancies flagged, dose form for each product, and route of administration for each product — with every difference listed as a discrete item rather than a single pass/fail verdict.
Example use cases
Brand vs generic substitution check
“I need to know if Zestril 10mg tablets and lisinopril 10mg tablets have exactly the same active ingredients, strengths, dose form, and route — list any differences individually so I can confirm they're interchangeable.”
Polypharmacy ingredient overlap audit
“My patient is taking both Tylenol Extra Strength and acetaminophen 500mg caplets from another brand — can you compare their RxNorm ingredient records and flag any differences in strength or dose form?”
Formulary equivalence verification
“We're updating our formulary and need to verify whether Nexium 40mg delayed-release capsules and esomeprazole 40mg delayed-release capsules share identical RxNorm active ingredients, strengths, and routes — show every field that differs.”
Technical details
Endpoint
POSThttps://med.halowerk.com/v1/ingredient-equivalenceWhen to prefer
Use this endpoint when you need a granular, field-level pharmaceutical equivalence comparison grounded in official RxNorm records — especially for brand-vs-generic checks, formulary substitution decisions, or clinical safety audits. Prefer this over a simple name lookup when ingredient strength differences matter, or when you need to distinguish between matching ingredients at different doses versus fully non-matching ingredients.
Side effects
- Drug name cannot be resolved to an RxNorm concept — returns unresolved product error
- Ambiguous drug name matches multiple RxNorm concepts — may return disambiguation error or pick one
- One or both products lack complete RxNorm ingredient data — comparison may be partial
- Misspelled drug name leads to no match found
- Non-drug product or veterinary drug name fails to resolve
