The initial peak (mean 1.9 ng/ml, range 1.0-3.4 mg/ml) occurred during 0.5 to 2 hours, and then mean plasma concentrations declined to 1.3 ng/ml at 3 hours. The concentration then increased again to reach a major peak level (mean 6.2 ng/ml, range 1.6-12.3 ng/ml) during 4-6 hours after dosing.

Plasma concentrations of ISDN have been measured after administration of increasing doses in the range 20-100 mg (as Cedocard Retard 20 tablets).

Means of peak concentrations of 4.2 ng/ml, 13.1 ng/ml, 20.7 ng/ml, 36.8 ng/ml and 34.9 ng/ml were measured after doses of 20 mg, 40 mg, 60 mg, 80 mg and 100 mg respectively.
