Before starting Argatroban: Stop all heparin (including catheter flushes), enoxaparin or dalteparin, and warfarin Obtain baselines labs (if none in past 24 hours)- CBC, PTT, PT/INR, Basic Metabolic Profile, LFT Dilute argatroban 250mg in either 250mL sodium chloride 0.9% or 250mL glucose 5% to give a final concentration of 1mg/mL. The optimal range for argatroban is APTT ratio 1.5 - 3.0 Check APTT ratio 2 hours after starting infusion, then adjust rate to achieve therapeutic range of 1.5 - 3.0 using the dose adjustment table

Clinical and Applied Low Dose of Argatroban Saline Flushes

Argatroban is monitored using the activated partial thromboplastin time (aPTT). The goal aPTT in seconds has been defined at UWMC/HMC as 60-80 seconds. Alternatively, it can be monitored with the direct thrombin inhibitor assay available at UWMC/HMC. This assay has a therapeutic range of 60 - 100 seconds for argatroban (different for other DTIs) When platelets > 150,000, initiate the Argatroban to Warfarin Transition Protocol. Pharmacy will dose warfarin and manage daily using the protocol. Monitoring PTT 4 hours after infusion started or any infusion rate change PTT every morning if no infusion rate change in past 24 hours CBC every morning 1 2.5-5 mg PO daily and overlap with argatroban for a minimum of 5 days If argatroban rate ≤ 2 mcg/kg/minute and INR > 4, stop infusion and obtain INR 4 hours after stopping infusion INR 2-3: continue with warfarin monotherapy INR < 2: restart argatroban and repeat above steps the following da also higher.

If the INR is ≥2.0, and at least a 5-day warfarin-argatroban overlap has been achieved, discontinue argatroban and continue warfarin (1.7-7.0) during argatroban monotherapy, 68.6 (44.5 -104) and 5.3 (2.4-16) maximally during cotherapy, 59.9 (38.7-92.2) and 4.0 (2.2-11.6) immediately before argatroban cessation during cothera-py, and 36.0 (25.6-60.2) and 2.3 (1.3-7.3) within a median 10-12 hours after argatroban cessation. Major bleeding occurred in Argatroban was held for 36 hours after surgery. During this period, his activated partial thromboplastin time (aPTT) ranged between 25.4 - 33.8 s. After that, argatroban was re-started and the aPTT kept between 48-55 s. On post-operative day (POD) 3, doppler studies revealed a venous thrombus in the right upper extremity Argatroban is a synthetic, nonpeptide small molecular weight (~500 Da) L-arginine derivative that reversibly inhibits thrombin by means of univalent binding to the active site (exosite 3; fig. 1A). 6 Argatroban is recommended for use in patients with renal failure as it undergoes hepatic elimination with a half-life of 40 to 50 min, but can be prolonged with moderate to severe hepatic.

argatroban was 0.3-0.7 mL/min/kg, suggest-ing an increase of 20% in argatroban clear-ance (15). Management and Monitoring of Anticoagulation At the beginning of CRRT, all patients re-ceived argatroban at a dose of 100 g/kg as a bolus injection followed by a continuous infu-sion of 1 g/kg/min. Argatroban was applie Nineteen patients received either argatroban or lepirudin prior to HIT-protocol implementation, while the remaining ten received either drug after the HIT protocol was implemented. Intervention: Implementation of HIT protocol occurred in March 2009. Patients were divided into pre-protocol and post-protocol groups If argatroban therapy is used concurrently with or following FFP or a thrombolytic, some centers decrease dose by half. Heparin-induced thrombocytopenia: Initial dose: 0.75 mcg/kg/minute by continuous IV infusion. Maintenance dose: Measure aPTT after 2 hours; adjust dose until the steady-state aPTT is 1.5 to 3 times the initial baseline value. Argatroban is a white, odorless crystalline powder that is freely soluble in glacial acetic acid, slightly soluble in ethanol, and insoluble in acetone, ethyl acetate, and ether.

Guidelines for the Management of Anticoagulant and Anti-Platelet Agent Associated Bleeding Complications in Adults Purpose: To be used as a common tool for all practitioners involved in the care of patients who present with bleeding problems related to use of anticoagulant and anti-platelet agents Argatroban is a new fast-acting synthetic thrombin inhibitor derived from arginine (Coron Art Dis 1996;7:455-58). The safety profile, as revealed in the original ARGAMI trial, suggests argatroban may have some advantages over heparin in select patients following myocardial infarction (MI). Although no statistically significant differences were. Extracorporeal membrane oxygenation (ECMO) have become more frequently used in daily ICU practice, heparin-induced thrombocytopenia (HIT) is a rare but life-threatening complication while on extracorporeal membrane oxygenation (ECMO). HIT confirmation directly impacts on anticoagulant strategy requiring no delay unfractionated heparin discontinuation to be replaced by alternative systemic. Argatroban is highly selective for thrombin with an inhibitory constant (K. i) of 0.04 µM. At therapeutic concentrations, Argatroban has little or no effect on related serine proteases (trypsin, factor Xa, plasmin, and kallikrein). Argatroban is capable of inhibiting the action of both free and clot-associated thrombin

Therefore, alternative regimens using argatroban are described below (Appendix A & B). 3.3 Care of recipient Post-transplant care of recipient of an organ from a donor with definite or probable VITT o In most respects, care will be as per standard protocols. Thromboprophylaxis can be given in the normal way unless VITT is suspected Anticoagulation in patients with heparin-induced thrombocytopenia type II who require parenteral antithrombotic treatment. Initially 2 micrograms/kg/minute, dose to be adjusted according to activated partial thromboplastin time, (by intravenous infusion) increased to up to 10 micrograms/kg/minute maximum duration of treatment 14 days

Argatroban administration is usually governed by local protocols that incorporate an initial dose, aPTT monitoring and increments or reductions in the dose of argatroban. Using a protocol to titrate the dose of argatroban has been shown to improve the quality of anticoagulation that a patient receives; time to goal aPTT and the time with goal aPTT are better than without a protocol Argatroban is a white, odorless crystalline powder that is freely soluble in glacial acetic acid, slightly soluble in ethanol, and insoluble in acetone, ethyl acetate, and ether.. Argatroban Injection is a sterile clear, colorless to pale yellow, slightly viscous solution in a single-use amber vial containing 250 mg/2.5 mL of argatroban Unfractionated heparin (UFH) binds to anti-thrombin III (AT-III), which enhances antithrombin's inhibition of several coagulation factors - especially factor Xa and factor IIa (thrombin). Low Molecular-Weight Heparin (LMWH) is a heterogeneous collection of heparin molecules with a lower average molecular weight compared to unfractionated heparin OBJECTIVE: Argatroban, a direct thrombin inhibitor, was evaluated for anticoagulation in continuous renal replacement therapy (CRRT) in critically ill patients with heparin-induced thrombocytopenia type II and acute renal failure. The investigation focused on predictors for the maintenance doses of argatroban with efficacy and safety of. Argatroban is a direct, selective thrombin inhibitor. The American College of Cardiologists (ACC) recommend using bivalirudin or argatroban in patients who have had, or at risk for, heparin induced thrombocytopenia (HIT) and are undergoing percutaneous coronary intervention. Argatroban is a non-heparin anticoagulant shown to both normalize platelet count in patients with HIT and prevent the.

Argatroban lacks major drug-drug interactions with CYP3A4/5 inhibitors such as erythromycin or with acetaminophen, warfarin, and digoxin. However, in patients with hepatic impairment, area under the concentration versus time curve (AUC), maximum concentration, and half-life of argatroban were increased approximately 2- to 3-fold, and clearance was one-fourth that of healthy volunteers Argatroban dosage requirements and outcomes in intensive care versus non-intensive care patients.

High-risk thromboembolism

The primary efficacy objective of the MOST trial is to determine if argatroban (100µg/kg bolus followed by 3µg/kg per minute for 12 hours) or eptifibatide (135µg/kg bolus followed by .75µg/kg/min infusion for two hours) results in improved 90-day modified Rankin scores (mRS) as compared with placebo in acute ischemic stroke (AIS) patients treated with .9mg/kg IV rt-PA within three hours. This is an update of the previous published guideline in 2006. It addresses the problem of thrombocytopenia developing in patients receiving heparin therapy and emphasises the importance of diagnosing heparin induced thrombocytopenia as a serious complication of therapy with a high morbidity and mortality Research Article Therapeutic Anticoagulation with Argatroban and Heparins Reduces Granulocyte Migration: Possible Impact on ECLS-Therapy?
