Changes in systolic and diastolic blood pressures and heart rate in healthy volunteers at adenosine infusion rates of 120 and 140 µg kg⁻¹ min⁻¹. ○ placebo; • SUNY4001. SUNY4001 infusion for 6 min using an infusion pump. P36m Differences in time dependency between placebo and dose level were tested by analysis of variance (from 3 min to 36 min). P24h Differences in time dependency between placebo and dose level were tested by analysis of variance (from 3 min to 24 h).
