atc code c02 atc code c02 atc code c02 antihypertensives 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 c02 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, qc02. national issues of the atc classification may include additional codes not present in this list, which follows the who version. c02a antiadrenergic agents, centrally acting c02aa rauvolfia alkaloids c02aa01 rescinnamine c02aa02 reserpine c02aa03 combinations of rauwolfia alkaloids c02aa04 rauwolfia alkaloids, whole root c02aa05 deserpidine c02aa06 methoserpidine c02aa07 bietaserpine c02aa52 reserpine, combinations c02aa53 combinations of rauwolfia alkaloids, combinations c02aa57 bietaserpine, combinations c02ab methyldopa c02ab01 methyldopa (levorotatory) c02ab02 methyldopa (racemic) c02ac imidazoline receptor agonists c02ac01 clonidine c02ac02 guanfacine c02ac04 tolonidine c02ac05 moxonidine c02ac06 rilmenidine c02b antiadrenergic agents, ganglion-blocking c02ba sulfonium derivatives c02ba01 trimetaphan c02bb secondary and tertiary amines c02bb01 mecamylamine c02c antiadrenergic agents, peripherally acting c02ca alpha-adrenoreceptor antagonists c02ca01 prazosin c02ca02 indoramin c02ca03 trimazosin c02ca04 doxazosin c02ca06 urapidil c02cc guanidine derivatives c02cc01 betanidine c02cc02 guanethidine c02cc03 guanoxan c02cc04 debrisoquine c02cc05 guanoclor c02cc06 guanazodine c02cc07 guanoxabenz c02d arteriolar smooth muscle, agents acting on c02da thiazide derivatives c02da01 diazoxide c02db hydrazinophthalazine derivatives c02db01 dihydralazine c02db02 hydralazine c02db03 endralazine c02db04 cadralazine c02dc pyrimidine derivatives c02dc01 minoxidil c02dd nitroferricyanide derivatives c02dd01 nitroprusside c02dg guanidine derivatives c02dg01 pinacidil c02k other antihypertensives c02ka alkaloids, excluding rauwolfia c02ka01 veratrum c02kb tyrosine hydroxylase inhibitors c02kb01 metirosine c02kc mao inhibitors c02kc01 pargyline c02kd serotonin antagonists c02kd01 ketanserin c02kx antihypertensives for pulmonary arterial hypertension c02kx01 bosentan c02kx02 ambrisentan c02kx03 sitaxentan c02kx04 macitentan c02kx05 riociguat c02kx52 ambrisentan and tadalafil c02kx54 macitentan and tadalafil c02l antihypertensives and diuretics in combination c02la rauwolfia alkaloids and diuretics in combination c02la01 reserpine and diuretics c02la02 rescinnamine and diuretics c02la03 deserpidine and diuretics c02la04 methoserpidine and diuretics c02la07 bietaserpine and diuretics c02la08 rauwolfia alkaloids, whole root and diuretics c02la09 syrosingopine and diuretics c02la50 combinations of rauwolfia alkaloids and diuretics including other combinations c02la51 reserpine and diuretics, combinations with other drugs c02la52 rescinnamine and diuretics, combinations with other drugs c02la71 reserpine and diuretics, combinations with psycholeptics c02lb methyldopa and diuretics in combination c02lb01 methyldopa (levorotatory) and diuretics c02lc imidazoline receptor agonists in combination with diuretics c02lc01 clonidine and diuretics c02lc05 moxonidine and diuretics c02lc51 clonidine and diuretics, combinations with other drugs c02le alpha-adrenoreceptor antagonists and diuretics c02le01 prazosin and diuretics c02lf guanidine derivatives and diuretics c02lf01 guanethidine and diuretics c02lg hydrazinophthalazine derivatives and diuretics c02lg01 dihydralazine and diuretics c02lg02 hydralazine and diuretics c02lg03 picodralazine and diuretics c02lg51 dihydralazine and diuretics, combinations with other drugs c02lg73 picodralazine and diuretics, combinations with psycholeptics c02lk alkaloids, excluding rauwolfia, in combination with diuretics c02lk01 veratrum and diuretics c02ll mao inhibitors and diuretics c02ll01 pargyline and diuretics c02lx other antihypertensives and diuretics c02lx01 pinacidil and diuretics c02n combinations of antihypertensives in atc-group c02 empty group
