atc code c09 atc code c09 atc code c09 agents acting on the renin–angiotensin system is a therapeutic subgroup of the anatomical therapeutic chemical classification system, a system of alphanumeric codes developed by the world health organization (who) for the classification of drugs and other medical products. subgroup c09 is part of the anatomical group c cardiovascular system. atc codes c cardiovascular system c01 cardiac therapy c02 antihypertensives c03 diuretics c04 peripheral vasodilators c05 vasoprotectives c07 beta blocking agents c08 calcium channel blockers c09 agents acting on the renin–angiotensin system c10 lipid modifying agents a b c d g h qi j l m n p r s v codes for veterinary use (atcvet codes) can be created by placing the letter q in front of the human atc code: for example, qc09. national issues of the atc classification may include additional codes not present in this list, which follows the who version. c09a ace inhibitors, plain c09aa ace inhibitors, plain c09aa01 captopril c09aa02 enalapril c09aa03 lisinopril c09aa04 perindopril c09aa05 ramipril c09aa06 quinapril c09aa07 benazepril c09aa08 cilazapril c09aa09 fosinopril c09aa10 trandolapril c09aa11 spirapril c09aa12 delapril c09aa13 moexipril c09aa14 temocapril c09aa15 zofenopril c09aa16 imidapril c09b ace inhibitors, combinations c09ba ace inhibitors and diuretics c09ba01 captopril and diuretics c09ba02 enalapril and diuretics c09ba03 lisinopril and diuretics c09ba04 perindopril and diuretics c09ba05 ramipril and diuretics c09ba06 quinapril and diuretics c09ba07 benazepril and diuretics c09ba08 cilazapril and diuretics c09ba09 fosinopril and diuretics c09ba12 delapril and diuretics c09ba13 moexipril and diuretics c09ba15 zofenopril and diuretics c09bb ace inhibitors and calcium channel blockers c09bb02 enalapril and lercanidipine c09bb03 lisinopril and amlodipine c09bb04 perindopril and amlodipine c09bb05 ramipril and felodipine c09bb06 enalapril and nitrendipine c09bb07 ramipril and amlodipine c09bb10 trandolapril and verapamil c09bb12 delapril and manidipine c09bb13 benazepril and amlodipine c09bx ace inhibitors, other combinations c09bx01 perindopril, amlodipine and indapamide c09bx02 perindopril and bisoprolol c09bx03 ramipril, amlodipine and hydrochlorothiazide c09bx04 perindopril, bisoprolol and amlodipine c09bx05 ramipril and bisoprolol qc09bx90 benazepril and pimobendan c09c angiotensin ii receptor blockers (arbs), plain c09ca angiotensin ii receptor blockers (arbs), plain c09ca01 losartan c09ca02 eprosartan c09ca03 valsartan c09ca04 irbesartan c09ca05 tasosartan c09ca06 candesartan c09ca07 telmisartan c09ca08 olmesartan medoxomil c09ca09 azilsartan medoxomil c09ca10 fimasartan c09d angiotensin ii receptor blockers (arbs), combinations c09da angiotensin ii receptor blockers (arbs) and diuretics c09da01 losartan and diuretics c09da02 eprosartan and diuretics c09da03 valsartan and diuretics c09da04 irbesartan and diuretics c09da06 candesartan and diuretics c09da07 telmisartan and diuretics c09da08 olmesartan medoxomil and diuretics c09da09 azilsartan medoxomil and diuretics c09da10 fimasartan and diuretics c09db angiotensin ii receptor blockers (arbs) and calcium channel blockers c09db01 valsartan and amlodipine c09db02 olmesartan medoxomil and amlodipine c09db04 telmisartan and amlodipine c09db05 irbesartan and amlodipine c09db06 losartan and amlodipine c09db07 candesartan and amlodipine c09db08 valsartan and lercanidipine c09db09 fimasartan and amlodipine c09dx angiotensin ii receptor blockers (arbs), other combinations c09dx01 valsartan, amlodipine and hydrochlorothiazide c09dx02 valsartan and aliskiren c09dx03 olmesartan medoxomil, amlodipine and hydrochlorothiazide c09dx04 valsartan and sacubitril c09dx05 valsartan and nebivolol c09dx06 candesartan, amlodipine and hydrochlorothiazide c09dx07 irbesartan, amlodipine and hydrochlorothiazide c09dx08 telmisartan, amlodipine and hydrochlorothiazide c09x other agents acting on the renin–angiotensin system c09xa renin-inhibitors c09xa01 remikiren c09xa02 aliskiren c09xa52 aliskiren and hydrochlorothiazide c09xa53 aliskiren and amlodipine c09xa54 aliskiren, amlodipine and hydrochlorothiazide
