Delparantag
Delparantag (PMX-60056) is a salicylamide derivative and an effective unfractionated heparin (UFH) and low molecular weight heparin (LMWH) reversing agent. Delparantag shows ability to neutralize the anticoagulation and bleeding effects of UFH and LMWH.

Biologische Aktivität
Delparantag is designed to restore coagulation by specifically binding to the pentasaccharide and disrupting UFH and LMWH interaction with antithrombin[1].
In heparinized plasma, Delparantag (PMX-60056) is more potent on a gravimetric basis than protamine at neutralizing both anti-Xa and anti-IIa activities. Delparantag is able to completely neutralize heparin at an approximate 2:1 gravimetric ratio. The amount of residual anti-IIa and anti-Xa activity was significantly less with Delparantag at a concentration of 50 mg/mL. In plasma anticoagulated with enoxaparin, Delparantag produces a concentration-dependent neutralization of anti-Xa activity. The amount of anti-Xa activity remaining after supplementation of the neutralizing agent is significantly less with Delparantag at concentrations above 25 mg/mL[2].

-
Animal Model:Male Sprague-Dawley rats (250-275 g) injected with UFH or LMWH (2.0 mg/kg)[2]
-
Dosage:0.5 mg/kg, 1.0 mg/kg, or 2.0 mg/kg
-
Administration:Intravenous injection; once
-
Result:Neutralizes the antithrombotic, anticoagulant, and bleeding effects of heparins as effectively as protamine sulfate and may be slightly more efficacious against LMWHs.
