For patients at least 75 years of age, the intravenous bolus was not given and the subcutaneous … Note the product strengths available on the Table 4. 2,000 IU (20 mg) SC once daily. Enoxaparin at therapeutic dose : 70 U/Kg b.i.d. Tinzaparin 10,000units/ml strength syringes are licensed for the prophylaxis of VTE. Most patients, regardless of weight or BMI, received standard 40‐mg/day doses. Enoxaparin Warfarin From therapeutic enoxaparin doses: Overlap therapeutic dose enoxaparin with warfarin for at least 5 days AND until INR is in therapeutic range for 24 hours. VTE: CrCl < 30: avoid use . Risk of Embolization Requiring Therapeutic Anticoagulation** See Table 1 for full prophylaxis dosing recommendations Warfarin DOACs High Risk* POD #1: Resume warfarin + enoxaparin 40mg SQ q24h^ POD #2-3: Therapeutic enoxaparin+ + bridge until INR within goal POD #1: Enoxaparin 40mg SQ q24hr^ POD #2-3: Resume home oral agent Disclosures. Enoxaparin dosing. 1 A disadvantage of enoxaparin is reliance on kidney function for excretion and potential accumulation of its anticoagulant effect in patients with declining renal function. There is literature supporting enoxaparin dosing for VTE prophylaxis in the general population, ... and clinical characteristics of the 173 patients who received enoxaparin for VTE prophylaxis are presented in Table 1. The main objective of this article is to examine the safety of weight-based enoxaparin dosing in obesity, as assessed by anti-factor Xa (anti-Xa) activity, bleeding, and recurrence. Our results confirm that increasing the initial enoxaparin dose to 1.5 mg/kg for patients 3 through 11 months of age facilitates achievement of target anti-factor Xa levels with fewer dosing changes. Prophylaxis of venous thromboembolic disease . 100 IU/kg (1 mg/kg) body weight SC once daily. 34 The drug is administered subcutaneously every 12 hours (see Table 130-4). Enoxaparin dosing requirements in pediatric patients vary with age. The manufacturer does not give any advice on dosing in obese patients, however local practice is as follows: At SFH, a dose of 1mg/kg s/c twice daily is given (up to a maximum of 150mg twice daily) if patients are greater than 100kg. A 5-year retrospective audit of patients with acute VTE, weighing > 100 kg, prescribed enoxaparin 1 mg/kg twice daily, with an anti-Xa level 2 to 6 hours post-dose. Weight-based dosing was first engineered for patients with morbid obesity, because using a fixed dose is most clearly ridiculous for these patients. The anti-Xa concentrations were significantly higher in the weight-based group compared with the BMI-stratified group (0.2960.08 international units/mL compared with (every 12 h) weight ≥ 65 Kg: 6.000 IU b.i.d. Methods: A retrospective chart review was conducted, which included morbidly obese patients receiving VTEP with adjusted-dose enoxaparin. Table 1 – Doses of tinzaparin for prophylaxis … In addition, the average peak anti-Xa level in these patients was .27 ± .1 IU/mL. (every 12 h) In order to easily calculate the correct therapeutic dose of enoxaparin for each patient, a simplified categorization will be applied, as follows: weight < 65 Kg: 4.000 IU b.i.d. -For patients managed by percutaneous coronary intervention (PCI), if the last subcutaneous dose of enoxaparin was less than 8 hours before balloon inflation, no additional dosing is required. Objective: To assess the impact of a weight-adjusted enoxaparin dosing algorithm on anti–factor Xa levels, thrombosis, and bleeding in morbidly obese patients. When reviewing the effect of standard enoxaparin dosing in critically ill patients, Costantini et al 8 concluded that standard dosing was frequently inadequate on the basis of trough anti-Xa levels, but interestingly, 11% of patients with adequate trough anti-Xa levels had venous thromboembolic events. Adjusted Value of Thromboprophylaxis in Hospitalized Obese Patients: A Comparative Study of Two Regimens of Enoxaparin (ITOHENOX) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Dosing enoxaparin based on weight simply makes pharmacological sense. Individual drug monographs in the Australian Medicines Handbook should be consulted to identify if weight-based dosing is required. Pooled analysis of 460 patients receiving once‑daily enoxaparin and 464 patients receiving twice‑daily enoxaparin indicated no significant difference between the two dosing regimens regarding VTE recurrence [odds ratio (OR)=1.48, 95%CI: 0.75‑2.89, P=0.26; I2=0%]. Listing a study does not mean it has been evaluated by the U.S. Federal Government. 1.4 23.9.19 Updated RAG ratings for GP/CSR There are 2 different strengths of tinzaparin syringes available – 10,000units/ml and 20,000units/ml. AF: CrCl 15 -50: 15 mg daily CrCl < 15: avoid use • VTE Treatment and Prophylaxis: CrCl < 30: avoid use . Enoxaparin clearance is decreased in renal insufficiency, making empirical dose reductions necessary to minimize bleeding risk. AF: if 2 of 3 criteria met then decrease to 2.5 mg BID: Age > 80 • Wt < 60 kg • Creatinine > 1.5 . 100 IU/kg (1 mg/kg) body weight SC once daily. For therapeutic treatment, the goal is to maintain an anti-factor Xa level between 0.5 and 1.0 units/ml in a sample taken 4 to 6 hours following subcutaneous injection. Table 1. updated with local decisions regarding colour classification & information on bridging therapy 1.3 30.11.17 Updated therapeutic indications and associated dosing regimens. The mean time from delivery to first enoxaparin dose also did not differ between groups (P=.61). Read our disclaimer for details. If the last subcutaneous dose was given more than 8 hours before balloon inflation, an IV bolus of 0.3 mg/kg should be given. 9-12 Current recommendations suggest that the enoxaparin dosing interval should be extended from every 12 to 24 hours in patients with a creatinine clearance less than 30 mL/min (to convert to milliliters per second, multiply by 0.0167). Patients receiving the higher enoxaparin dosing regimen had higher body weight, increased frequency of atrial fibrillation, more severe hypoxemia upon admission, and received a “more aggressive” treatment for COVID-19; the length of stay was also longer. Table 1: Volumes of Clexane required for each prescribed dose. A study by Bauman et al (2009) evaluated the dosing requirements of enoxaparin in children and infants, focusing on the effect of increasing the starting dose of enoxaparin and the length of time required to reach therapeutic anti-Xa levels. Notably, regardless of the dosing strategy, in our series enoxaparin was early given (< 48 h from admission in 81% of patients). 4.6 Dosing 4.6.1 Therapeutic anticoagulation Dose according to actual body weight (rounded down to the nearest 10 kg) and renal function as detailed in Tables D and E (see also the Medication Dosing Calculator available via desktop icon on Queensland Health computers or via QHEPS). Enoxaparin dosing in the elderly using adjusted body weight @article{Leri2009EnoxaparinDI, title={Enoxaparin dosing in the elderly using adjusted body weight}, author={Frederick Leri and Stephen J. Voyce and S. Scialla and William Glavich and E. Dzielak and R. Smego and John Guzek}, journal={Journal of Thrombosis and Thrombolysis}, year={2009}, volume={28}, pages={348-353} } Lovenox should be used with care in geriatric patients who may show delayed elimination of enoxaparin. Therefore, we adopted intermediate-dose thromboprophylaxis for critically ill patients with COVID-19 with enoxaparin (0.5 mg/kg twice daily), as described in Table 1, as our new standard of care. Clearance has been correlated with lean body weight for opioids such as fentanyl,10 anaesthetics such as propofol,10 ranitidine, lithium and enoxaparin.8 Updated monitoring requirements. (ENOXAPARIN SODIUM) DOSING CHART THERAPEUTIC INDICATIONS Inhixa is indicated in adults for: 1. Table 6. For patients younger than 75 years of age, enoxaparin was given as a single 30 mg intravenous bolus plus a 1 mg/kg subcutaneous dose followed by a subcutaneous injection of 1 mg/kg every 12 hours. No significant difference in major hemorrhagic complications was noted (OR=1.21, 95%CI: 0.52‑2.81, P=0.66; I2=0%). Prophylaxis of venous thromboembolic disease in moderate and high risk surgical patients, in particular those undergoing orthopaedic or general surgery including cancer surgery. The enoxaparin dosing strategy was adjusted according to the patient's age and renal function. The dosages were selected based on several single-center studies suggesting higher rates of attainment of target anti-FXa activity with higher-dose enoxaparin ( 9 , 10 ). Dosing Adjustments and Considerations AF: CrCl 15-30: 75 mg BID CrCl < 15: avoid use . Dosage table for patients with severe renal impairment (creatinine clearance [15-30] mL/min): Indication. Enoxaparin sodium, a low-molecular-weight heparin, has a predictable pharmacokinetic profile and dose-response curve, allowing simplified dosing without the need for vigilant monitoring through laboratory tests. Dosing regimen. Table 3: Comparison of Weight-Based to Body Mass Index-Stratified Enoxaparin Dosing in Morbidly Obese Women After Cesarean Delivery . There were 37 patients in the study who received 2 different courses of enoxaparin during their hospital stay. (every 12 h) to Table 1 for dosing information. 2. Enoxaparin (Lovenox) contains 110 anti-factor X units/mg and is the most commonly used product. and in particular morbid obesity, are listed in Table 2. Treatment of unstable angina and NSTEMI. Treatment of DVT and PE. The mean enoxaparin dose in the weight-based group was 60.7610.5 mg compared with 41.465.2 mg in the BMI-stratified group (P,.001). In the CONKO-004 trial, the administration of weight-adjusted enoxaparin at 1 mg/kg daily for 3 months resulted in an approximate 85% risk reduction in the incidence of VTE without an increase in major hemorrhage compared with no anticoagulation in ambulatory patients. Enoxaparin dosing was assessed in 343 inpatients, of whom 31% were overweight and 27% were obese. At NUH, a dose of 1mg/kg s/c twice daily is given if patients are greater than 150kg. There were no reported adverse reactions to enoxaparin in either group. However, optimizing dose based on weight makes sense for patients within a lower weight range as well. Analysis revealed only two cases of enoxaparin dose increases among the 92 obese patients, and little individualised dosing overall. Careful attention to dosing intervals and concomitant medications (especially antiplatelet medications) is advised.
