title: Nisoldipine versus isosorbide dinitrate in coronary heart disease: results of a double-masked study.
abstract: The efficacy and tolerability of a twice-daily dose of 5 mg of nisoldipine versus 40 mg of sustained-release isosorbide dinitrate (ISDN) were compared in a randomized, double-masked study in 91 patients. During the 21-day treatment period, the mean time taken during bicycle ergometry to the appearance of an ST segment depression of at least 0.1 mV compared with the resting value increased from 287 +/- 129 seconds to 391 +/- 150 seconds in the nisoldipine group and from 254 +/- 140 seconds to 350 +/- 191 seconds in the ISDN group. The mean value at the end of treatment calculated by using analysis of covariance was 383 seconds in both groups. The difference between the two treatment groups was not statistically significant. The mean ST segment depression at individually maximal workload decreased from 0.19 +/- 0.07 mV to 0.12 +/- 0.08 mV in the nisoldipine group and from 0.18 +/- 0.07 mV to 0.14 +/- 0.08 mV in the ISDN group. The mean total duration of exercise increased from 420 +/- 161 seconds to 497 +/- 140 seconds in the nisoldipine group and from 425 +/- 167 seconds to 456 +/- 168 seconds in the ISDN group. In the nisoldipine group, 9 patients reported 12 adverse events that were considered to be possibly or probably related to the test medication; in the ISDN group, 13 patients reported 26 adverse events. Although the anti-ischemic effect of the two treatments was comparable, nisoldipine was descriptively superior to ISDN in terms of tolerability.
