High treatment doses are contraindicated in acute bleedings such as cerebral or gastrointestinal haemorrhage. LMWHs are more dependent on renal function for their excretion …
Witryna25 sty 2012 · The development of biosimilar versions of low molecular weight heparins (LMWHs) raises real medical concerns. To illustrate this, we have chosen as an example the specific clinical setting of antithrombotic management of acute coronary syndromes (ACS). In this indication, the LMWH enoxaparin has consistently shown its superiority … WitrynaXa activity. Therefore the anti-Xa activity of LMWHs is largely intact in the face of PF4 inhibition [10]. However, the anti-IIa action of LMWH is reduced by PF4, and overall antithrombotic activity is retained [10] In contrast, UHF can be completely inactivated in the presence of PF4 [10].
Witryna23 lip 2010 · Low-molecular-weight heparins (LMWHs) have several positive therapeutic effects and can also form immunostimulatory complexes with plasma proteins, such as platelet factor 4 (PF4).
