低分子量肝素由天然肝素分離或是降解得到。臨床用于預防手術后血栓栓塞、預防深靜脈血栓形成、肺栓塞、血液透析時體外循環(huán)的抗凝劑、末梢血管病變等。
低分子量肝素是低分子量肝素鈉鹽，通過從豬肉腸道粘液中分離肝素的硝基酸脫聚而獲得。作為一種新的抗血栓類，低分子量肝素鈉在預防或治療劑量下施用時提供立即和持續(xù)的抗血栓活性。它用于預防血液透析期間凝血和預防深靜脈血栓（DVT）。浩然生物制藥可供應具有以下規(guī)格的散裝低分子量肝素鈉。各種規(guī)格的產(chǎn)品也可以根據(jù)客戶的要求進行準備。
Dalteparin Sodium (Low Molecular Weight Heparin Sodium) (LMWH-Na) is the sodium salt of Low Molecular Weight Heparin obtained by nitrous acid depolymerization of heparin from pork intestinal mucosa.
As a new antithrombotic class, Dalteparin Sodium provides immediate and sustained antithrombotic activity when administered in prophylactic or therapeutic dosage. It is indicated for prevention of clotting during hemodialysis and prophylaxis of Deep Venous Thrombosis (DVT).
