How this service works
Match a misspelled or branded drug name to RxNorm: best candidates with RxCUI identifiers, names and match scores.
Output
Returns a best match object with the normalized drug name, RxCUI identifier, match score, and term type, plus an ordered list of additional candidate matches. Also includes the original query, data source URL, a summary verdict, and a disclaimer.
Example use cases
EHR drug entry spell-check
“A nurse typed 'amoxacillin' into our EHR system — can you match that to the correct RxNorm entry and give me the RxCUI so we can standardize it?”
Branded-to-generic drug resolution
“What is the RxNorm RxCUI for Advil? I need the official normalized name and the top matching candidates with their scores.”
Medication reconciliation fuzzy match
“A patient wrote 'Zertec' on their intake form — can you match that to the correct RxNorm drug name and give me the RxCUI identifier?”
Technical details
Endpoint
GEThttps://medical-codes.x402tookit.com/drug-name-match?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a possibly misspelled, branded, or informal drug name to a standard RxNorm RxCUI identifier and normalized name — especially useful for medication reconciliation, EHR data standardization, or any workflow requiring canonical drug identifiers. Prefer this over a full RxNorm profile lookup when the primary need is fuzzy matching and candidate ranking rather than detailed drug attributes.
Side effects
- Drug name not found in RxNorm — returns empty candidates list
- Very short or ambiguous input may return low-confidence scores with many candidates
- Network or upstream RxNorm API errors may return a degraded flag
- Missing required 'name' query parameter returns a validation error
