Limaprost(OP1206) is a PGE1 analog and potent platelet adhesion inhibitor.

Target: Others

Limaprost, an alprostadil (prostaglandin E1) analogue, is a vasodilator that increases blood flow and inhibits platelet aggregation. Limaprost is a n analog of PGE1 with structural modifications intended to give a prolonged half-life and greater potency. It is orally active in both guinea pigs and rats at doses of 100 mg/kg as an inhibitor of ADP and collagen induced platelet aggregation. It is 10-1,000 times more potent than PGE1 as a platelet adhesive inhibitor, measured in vitro. Intra-coronary injection (100 ng/kg) or intravenous injection (3 mg/kg) in anesthetized dogs causes vasodilation and increased coronary blood flow by 60-80%. Significant hypotensive effects were seen at 100 and 300 mg/kg orally in rats [1].
