atc code c08 atc code c08 atc code c08 calcium channel blockers 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 c08 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, qc08. national issues of the atc classification may include additional codes not present in this list, which follows the who version. c08c selective calcium channel blockers with mainly vascular effects c08ca dihydropyridine derivatives c08ca01 amlodipine c08ca02 felodipine c08ca03 isradipine c08ca04 nicardipine c08ca05 nifedipine c08ca06 nimodipine c08ca07 nisoldipine c08ca08 nitrendipine c08ca09 lacidipine c08ca10 nilvadipine c08ca11 manidipine c08ca12 barnidipine c08ca13 lercanidipine c08ca14 cilnidipine c08ca15 benidipine c08ca16 clevidipine c08ca17 levamlodipine c08ca51 amlodipine and celecoxib c08ca55 nifedipine, combinations c08cx other selective calcium channel blockers with mainly vascular effects c08cx01 mibefradil c08d selective calcium channel blockers with direct cardiac effects c08da phenylalkylamine derivatives c08da01 verapamil c08da02 gallopamil c08da51 verapamil, combinations c08db benzothiazepine derivatives c08db01 diltiazem c08e non-selective calcium channel blockers c08ea phenylalkylamine derivatives c08ea01 fendiline c08ea02 bepridil c08ex other non-selective calcium channel blockers c08ex01 lidoflazine c08ex02 perhexiline c08g calcium channel blockers and diuretics c08ga calcium channel blockers and diuretics c08ga01 nifedipine and diuretics c08ga02 amlodipine and diuretics
