Beraprost is a stable, orally active prostacyclin analogue. Beraprost acts by binding to prostacyclin membrane receptors ultimately inhibiting the release of Ca2+ from intracellular storage sites. This reduction in the influx of Ca2+ has been postulated to cause relaxation of the smooth muscle cells and vasodilation. Beraprost is indicated for the treatment of pulmonary hypertension and improvement of ulcers, pain & feeling of coldness associated with chronic arterial occlusion. In addition beraprost displays thyroid hormone receptor antagonistic properties.

Sample Use Guides

In Vivo Use Guide

Improvement of ulcers, pain & feeling of coldness associated with chronic arterial occlusion, Adult : 120 mcg daily in 3 divided doses. Primary pulmonary Hypertension: 60 mcg daily in 3 divided doses. Gradually increase dose if needed, up to a max of 180 mcg daily in 3-4 divided doses.

Route of Administration: Oral

In Vitro Use Guide

In suppressing platelet aggregation beraprost was especially potent with IC50 of 0.2-0.5 nM when platelets were activated by U46619, a thromboxane A2 analogue, or low concentrations of collagen which activates platelets through thromboxane A2 production. The IC50 values were 2-5 nM with ADP and epinephrine, which induce the formation of small aggregates independently of thromboxane A2 production.
