Pharmacokinetics of intravenous/subcutaneous Enoxaparin in patients with acute coronary syndrome undergoing percutaneous coronary interventions.

Plasma anti-Xa activity after Enoxaparin administration in patients with acute coronary syndrome (ACS) undergoing coronary angiography and percutaneous coronary intervention (PCI) has not been well established. Patients presenting with non-ST-elevation ACS received an initial dose (0.75 mg/kg) of Enoxaparin intravenously (IV), with subsequent doses (1 mg/kg) subcutaneously (SC) beginning 8 hr following the IV dose.
