Objective We evaluated the early pharmacodynamic profile of the combined 30 mg intravenous and 1 mg/kg subcutaneous enoxaparin loading utilized in the TIMI 11B and ExTRACT TIMI 25 trials. Background It has not been reported whether anti-Xa levels appropriate for percutaneous coronary intervention (PCI) can be reliably achieved within 2 h utilizing this regimen. Methods Twenty-six patients with acute coronary syndrome (ACS) treated with this regimen had anti-Xa levels measured at 5 min, 2, 4, 6 and 8 h. Results Seventy-six percent of patients had anti-Xa levels above 0.5 IU/ml at 5 min. Dose-response curves showed all patients to have anti-Xa levels above 0.5 IU/ml within 1 h. Anti-Xa remained in the targeted range for PCI (0.5 to 1.8 IU/ml) at 2, 4, 6 and 8 h in all patients. Conclusion This regimen is well suited for ACS treatment with an invasive strategy, including the rapid transition to early and rescue PCI.
