概要
Beraprost is an organic heterotricyclic compound that is (3aS,8bS)-2,3,3a,8b-tetrahydro-1H-benzo[b]cyclopenta[d]furan in which the hydrogens at positions 1R, 2R and 5 are replaced by (3S)-3-hydroxy-4-methyloct-1-en-6-yn-1-yl, hydroxy and 3-carboxypropyl groups, respectively. It is a prostaglandin receptor agonist which is approved to treat pulmonary arterial hypertension in Asia. It has a role as a vasodilator agent, an antihypertensive agent, a platelet aggregation inhibitor, a prostaglandin receptor agonist and an anti-inflammatory agent. It is a secondary allylic alcohol, a monocarboxylic acid, an organic heterotricyclic compound, a secondary alcohol and an enyne. It is a conjugate acid of a beraprost(1-).

Pharmacodynamics
Beraprost is a stable, orally active prostacyclin analogue with vasodilatory, antiplatelet and cytoprotective effects. Beraprost is generally well tolerated and appears to be an effective agent in the treatment of patients with Buerger's disease and arteriosclerosis obliterans. Comparative data from a large randomised trial indicated that the drug appears as effective as ticlopidine in patients with these conditions. In patients with intermittent claudication, significant benefits of beraprost compared with placebo were reported in a randomised clinical trial; however, the use of beraprost in these patients is not supported by recent preliminary unpublished data from a large, phase III, placebo-controlled study. Limited data suggest some efficacy with long-term beraprost treatment of patients with PAH, where options are few and where oral administration of the drug could be a considerable advantage over intravenous prostacyclin (PGI2) therapy.
Mechanism of Action
Beraprost acts by binding to prostacyclin membrane receptors ultimately inhibiting the release of Ca<sup>2+</sup> from intracellular storage sites. This reduction in the influx of Ca<sup>2+</sup> has been postulated to cause relaxation of the smooth muscle cells and vasodilation.
MeSH Pharmacological Classification
Drugs or agents which antagonize or impair any mechanism leading to blood platelet aggregation, whether during the phases of activation and shape change or following the dense-granule release reaction and stimulation of the prostaglandin-thromboxane system.
Drugs used to cause dilation of the blood vessels.
