The heart rate-lowering rate, defined as percent change from the baseline to SBE-��-CD clinical trial CCTA, was −14.46 ± 8.4 % and the reduction rate showed statistical significance (paired t test: p < 0.0001) as did the mean heart rate at CTTA. The heart rate then rapidly recovered toward the baseline value at approximately

6 min after completion of the study drug administration (Fig. 3).
