Cardiovascular drugs in Czechoslovakia--registration and consumption data.

Data on registration and consumption of cardiovascular drugs in Czechoslovakia were sorted from the computerized Drug Information System (DIS) for a detailed analysis. Cardiovascular drugs (including antiarrhythmics, cardiac glycosides, diuretics, antihypertensive agents and vasodilators) represent at present 10% of all registered drugs in Czechoslovakia with an ever increasing trend over the last ten years. For economical analysis of consumption of cardiovascular drugs, three methodological approaches (expenditure figures, material units--number of packages and DDD (Defined Daily Dosis), as a technical unit of measurement) were chosen.
