The antiaggregation and hemodynamic effects of the new prostacyclin analogue beraprost sodium were investigated in a randomized, placebo-controlled, double-blind clinical trial of Latin-square design. Twelve healthy Caucasian males randomly received 8-day oral treatments of 20, 40, and 60 micrograms of beraprost sodium and a placebo. One-week washout periods followed each treatment. Pharmacokinetic and pharmacodynamic measurements were performed on days 1 and 8 for each period of treatment. All three doses of beraprost sodium significantly inhibited platelet aggregation on day 8 (compared with placebo) during the 1st h after drug intake. Incubation of the 60-micrograms beraprost sodium samples with ADP (2, 5, and 10 microM) and collagen (1.25 micrograms/mL) decreased platelet aggregation by 10, 19, 16, and 6 +/- 4% (mean +/- SE), respectively, compared with placebo. No significant hemodynamic effects on blood pressure, heart rate, and digital pulse were observed. The 60-micrograms dose of beraprost sodium did significantly decrease the IRZ index (which may reflect the left ventricular pre-ejection period) on days 1 and 8. Some subjects experienced headache and facial flushing, effects that were dose dependent and reversible. Beraprost sodium at 20- to 60-micrograms doses exerts platelet antiaggregation (day 8 of therapy) and slight hemodynamic (days 1 and 8 of treatment) effects in Caucasian males. Beraprost sodium hemodynamic effects and potential benefits in patients with cardiovascular disease should be explored further.

Beraprost sodium, an orally active prostaglandin I2 analog with vasodilatory, cytoprotective, antiplatelet, antithrombotic, and anti-inflammatory effects, 120 microg daily for 8 weeks, decreased plasma D-dimer, a marker of intravascular coagulation, and von Willebrand factor, a marker for endothelial injury, in 100 chronic peritoneal dialysis patients. Total cholesterol, triglycerides, high-density lipoprotein, apolipoprotein A1, apolipoprotein B, albumin, prealbumin, fibrinogen, troponin-T, and high-sensitivity C-reactive protein levels were not changed. Three patients complained of headache and 1 patient experienced facial flushing; however, no serious adverse effects were observed. These results suggest that beraprost sodium is effective in partially reversing the thrombogenic coagulation profile and endothelial injury in chronic peritoneal dialysis patients.
