- Subcut / IVHeparin Sodium
- Mechanism of Action
- Binds to and activates antithrombin III, which as a heparin-ATIII complex inactivates factors IIa (thrombin) and Xa
- Adverse Effects
- Intravenous heparin is monitored using activated partial thromboplastin time (APTT). Alternatively (particularly in the setting of antiphospholipid syndrome), a heparin anti-factor Xa assay can be used.
