C CARDIOVASCULAR SYSTEMThis group comprises substances used for the treatment of cardiovascular conditions.
Drugs used for the treatment of hypertension are classified in C02 - Antihypertensives, C03 - Diuretics, C07 - Beta blocking agents, C08 - Calcium channel blockers, and C09 - Agents acting on the renin-angiotensin system. For the classification of combination products of antihypertensives from different ATC groups, the following ranking should be used, from higher to lower precedence: C09, C07, C08, and C03.
C02 ANTIHYPERTENSIVES
See also C03 - Diuretics, C07 - Beta blocking agents, C08 - Calcium channel blockers and C09 - Agents acting on the renin-angiotensin system.
Antihypertensives are mainly classified at 3rd levels according to the mechanism of action. Most headings are self-explanatory:
C02A Antiadrenergic agents, centrally acting
C02B Antiadrenergic agents, ganglion-blocking
C02C Antiadrenergic agents, peripherally acting
C02D Arteriolar smooth muscle, agents acting on
C02K Other antihypertensives
C02L Antihypertensives and diuretics in combination
C02N Combinations of antihypertensives in ATC gr. C02
| The oral DDDs are based on the average doses needed to reduce the blood pressure to a normal level in patients with mild-moderate hypertension. Parenteral DDDs are based on dosages used for the treatment of hypertensive crises and are based on the content of the active ingredient pr. vial (ampoule). |
C02D ARTERIOLAR SMOOTH MUSCLE, AGENTS ACTING ON
See also C08 - Calcium channel blockers.
C02DB Hydrazinophthalazine derivatives
Combinations with diuretics, see C02LG - Hydrazinophthalazine derivatives and diuretics.
Combinations of isosorbide dinitrate and hydralazine are classified in C01DA - Organic nitrates.
| The oral DDD of dihydralazine is higher than the parenteral DDD. The parenteral DDD is given as the chloride salt while the oral DDD is given as the mesylate salt. |
| ATC code | Name | DDD | U | Adm.R | Note |
| C02DB03 | endralazine | 10 | mg | O |
