CALCIUM CHANNEL BLOCKERS
ATC/DDD code C08 for CALCIUM CHANNEL BLOCKERS
The calcium channel blockers are classified according to selectivity of calcium channel activity and direct cardiac effects. The ATC 4th levels are subdivided according to chemical structure.
Combinations with ergot alkaloids (C04AE) are classified in this group by using the 50-series.
Combinations with diuretics are classified in C08G.
Combinations with ACE inhibitors are classified in C09BB.

The DDDs for calcium channel blockers are based on the treatment of mild-moderate hypertension, although some are used for other indications (e.g. angina pectoris).
The DDDs for oral and parenteral preparations are equal and are based on the oral dose, since oral preparations represent the major fraction of the total consumption.
