What does “US adopted names council” mean for sartan drugs?
The United States adopted name (USAN) is the standardized system for nonproprietary drug names used in the US. Under that system, many angiotensin II receptor blockers (ARBs) received “-sartan” stems that clearly identify the drug class in the name. ARBs block the angiotensin II type 1 (AT1) receptor and are commonly used for conditions like hypertension.
What is the “-sartan” stem, and how is it used?
“Sartan” is the class stem used in USAN names for angiotensin II receptor antagonists (ARBs). For example, drugs with names ending in “-sartan” are typically ARBs, such as losartan, valsartan, and irbesartan.
Does “sartan” always mean angiotensin II receptor antagonist?
In typical naming practice, yes: the “-sartan” stem indicates an angiotensin II receptor antagonist class. This naming convention is meant to help clinicians and pharmacists quickly recognize drug class from the generic name.
Which USAN “-sartan” drugs are examples?
Common ARBs with the USAN “-sartan” suffix include losartan, valsartan, and irbesartan. These are widely recognized examples of angiotensin II receptor antagonists that use the class stem.
If a drug name ends differently, could it still be an ARB?
ARBs are designed to carry the “-sartan” stem in their generic names. If a generic name does not use “-sartan,” it is less likely to be an ARB and may instead belong to a different class (for example, ACE inhibitors, which do not use the “-sartan” stem).
What about regulations or switching between brands and generics?
The USAN naming system is separate from brand names. Patients may see different brand products for the same generic ARB name. When switching, the key is the generic (USAN) name, since it indicates the drug class and active ingredient.
