Renin-Angiotensin-Aldosterone System (RAAS) Blocker, Drug Exposure

This concept set identifies renin-angiotensin-aldosterone system-blocking medications including angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), and other agents acting on the renin-angiotensin system. This medication concept set includes the following ingredients: aliskiren, azilsartan, benazepril, candesartan, captopril, cilazapril, enalapril, eprosartan, fosinopril, imidapril, irbesartan, lisinopril, losartan, moexipril, olmesartan, perindopril, quinapril, ramipril, spirapril, telmisartan, trandolapril, valsartan, and zofenopril. It also includes combinations of these ingredients with other antihypertensive medications. This code list was generated by taking the descendants of all the ACE, ARB, and other RAAS agent ingredients of interest, and string matching on the concept_name of the ingredient. Technical Note: This concept set was created when ingredients were required for some sites. It could be enhanced by using SCDF drug levels and taking descendants, making this easier to refresh. This concept set is identical to its predecessor, but it has been expanded to include RxNorm Extension codes in addition to RxNorm codes.
