What does RxNorm 29046 lisinopril ingredient official mean?
RxNorm is a standardized drug database used in U.S. health IT. The code you provided (RxNorm 29046) corresponds to the active ingredient lisinopril, with the “ingredient official” naming indicating the official RxNorm ingredient concept for that substance.
In practice, “ingredient official” is the ingredient-level concept (not a specific brand drug or dose form). It’s used to represent lisinopril consistently across different products in systems that exchange medication data.
Is this the same lisinopril used in ACE inhibitor brand and generic products?
Yes. RxNorm’s ingredient-level concept is shared across many specific products (brands and generics) that contain lisinopril as the active ingredient. Those product-level concepts typically carry additional details like strength, dosage form, and packaging, while 29046 is the ingredient anchor.
How do you use this in EHRs or prescribing systems?
Systems commonly map between:
- ingredient concepts (like RxNorm 29046 for lisinopril), and
- specific drug products (which include strength and form)
This helps ensure that reports and analytics treat “lisinopril” the same way even when a patient switches brands or formulations.
Where can I verify the RxNorm concept details?
You can look up RxNorm concept details for the exact code 29046 directly in the official RxNorm resources (for example, via the National Library of Medicine/RxNorm search).
If you want, paste the URL or the text you see on the RxNorm entry page for 29046, and I can help interpret the fields shown there.
