[Comparison of dinitrate isosorbide retard forms in ischemic heart disease patients with stable effort angina].

AIM

To compare antianginal and anti-ischemic efficiency and tolerance of two forms of isosorbide dinitrate--cardiket-retard 120 mg and cardiket-retard 40 mg in IHD patients with stable effort angina.

MATERIAL AND METHODS

The study included 18 IHD patients with stable angina of functional class II (5 patients) and III (13 patients). The trial was open cross-over. The treatment with both the forms lasted 1 month. Frequency of anginal attacks and exercise tolerance by veloergometry data were assessed.

RESULTS

A significant decrease in the number of anginal attacks and greater exercise tolerance was recorded in cardiket 120 mg intake once a day. Both forms were well tolerated, serious side effects were absent.

CONCLUSION

Comparison of the two isosorbide dinitrate dosage forms--cardiket 120 mg once a day and cardiket 40 mg 3 times a day--showed that the former is superior by clinical efficiency.
