Guide to Anticoagulant Therapy: Heparin Circulation

WebLow-molecular-weight heparin is cleared almost exclusively by the kidney, and the drug can accumulate in patients with renal insufficiency. Because Low-molecular-weight heparin binds less avidly to heparin-binding proteins in plasma than heparin, LMWH produces a more predictable dose response, and resistance is rare. WebThe slower, unsaturable mechanism of clearance is largely renal. At therapeutic doses, a considerable proportion of heparin is cleared through the rapid saturable, dose-dependent mechanism (Figure 6). These kinetics make the anticoagulant response to heparin nonlinear at therapeutic doses, with both the intensity and duration of effect rising ... itk computer gmbh https://trabzontelcit.com
