Monitoring of Argatroban and Lepirudin: What is the Input

  1. Multiple regression analyses revealed that the TT predicted 54% of argatroban and 42% of lepirudin levels, but no significant impact was seen for PT or aPTT. The aPTT-guided monitoring of DTI therapy leads to a high percentage of patients with inaccurate plasma levels, hence resulting to either undertreatment or overtreatment. Knowledge of baseline values prior to DTI therapy and inclusion of clinical settings are essential for dosing DTIs when using aPTT. However, due to several limitations.
  2. Die Behandlung mit Argatroban Ac-cord wird im Allgemeinen anhand der aktivierten partiellen Thromboplastin-zeit (aPTT) kontrolliert. Gerinnungstests (einschließlich aPTT) erreichen in der Regel inner-halb von 1-3 Stunden nach Erstan-wendung von Argatroban Accord den Gleichgewichtszustand (Steady State).

In der klinischen Anwendung von Argatroban bei Intensivpatienten entstand der Eindruck, dass bei diesem Patientenkollektiv deutlich niedrigere Dosierungen erforderlich sind als in der Fachinformation für Patienten mit normaler und selbst mit eingeschränkter Leberfunktion.
  5. 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)

Dabigatran, though it requires no regular monitoring, represents a special case compared to argatroban and bivalirudin. Its half-life of 12-17 hours and its indication for long-term therapy make it more frequently implicated in hemorrhage or thrombosis.15 Consequently, dabigatran should be assayed in all th gesetzten Argatroban-Clearance länger als 4 Stunden dauern. Laboruntersuchungen: Zur Kontrolle der Infusion wird die Durchführung von aPTT-Bestimmungen empfohlen. Obwohl ande-re Plasmagerinnungstests wie Prothrom-binzeit (PT, z.

Argatroban interferes with the INR assay; earlier cessation of argatroban could result in a lapse in therapeutic anticoagulation. Please seek haematology advice To the Editor: Argatroban is one of several intravenous direct thrombin inhibitors that are commonly used in the treatment of heparin‐induced thrombocytopenia. Currently, the activated partial thromboplastin time (aPTT) is recommended for monitoring argatroban infusions 1 There is increasing evidence suggesting that the activated partial thromboplastine time (aPTT), which is recommended for dosage monitoring, correlates poorly with serum argatroban concentration in critically ill patients. Therefore it may be badly suited to determine the correct dosing Insbesondere bei Patienten mit heparininduzierter Thrombozytopenie (HIT-Typ II), die eine suffiziente und gut steuerbare Antikoagulation benötigen, stellt Argatroban eine attraktive therapeutische Alternative zu den bisher verwendeten Antikoagulanzien, wie Lepirudin oder Heparinoiden, dar. Die Überwachung der Antikoagulation kann mit der aktivierten partiellen Thromboplastinzeit (aPTT) erfolgen. Argatroban ist in Deutschland seit Juni 2005 zur Antikoagulation bei Patienten mit HIT-Typ II.

Monitoring Argatroban monitoring is detailed in table 4. Target ranges for the various tests used have not been established in an outcome-based setting. Argatroban increases thrombin-based coagulation times (prothrombin time [PT] and the PT-derived international normalised ratio [INR] expression; activated partial thromboplastin time (aPTT); thrombin time (TT); activated clotting time [ACT.

Argatroban (Argatra®, Novastan®) ist ein direkter Thrombininhibitor, welcher als Heparinalternative zur Antikoagulation bei erwachsenen Patienten mit heparininduzierter Thrombozytopenie Typ II (HIT II) eingesetzt werden kann., die einer parenteralen antithrombotischen Therapie bedürfen. Zur Diagnostik der HIT II sollte zunächst die 4T. Clinical Monitoring of Direct Thrombin Inhibitors Using the Ecarin Clotting Time Simon de Denus, M.S., and Sarah A. Spinler, Pharm.D., FCCP (Pharmacotherapy 2002;22(4):433-435) Direct thrombin inhibitors such as lepirudin, bivalirudin, and argatroban constitute a novel class of anticoagulants. The mechanism of action of these agents differs from heparin in that they directly inhibit the. Argatroban is a competitive thrombin inhibitor. Its plasma half-life is 45 minutes. 20 Argatroban is licensed for treatment and prevention of HIT-associated thrombosis and for anticoagulation during PCI when heparin is contraindicated because of a recent history of HIT. 6 Activity can be monitored by ACT or aPTT. 2 Laboratory monitoring.

According to our experience both DTI can be started with a dose of 0.06 mg/kg/h. We suggest adjusting dosages by steps of 0.015 mg/kg/h (corresponding to 0.25 µg/kg/min) for agatroban and at least 0.05 mg/kg/h for bivalirudin. Therapeutic concentrations are 0.4-0.8 µg/ml for. aPTT and anti-IIa activity assays were used to monitor the dose of argatroban. The mean baseline aPTT value was 45.0 ± 9.8 sec and increased to 78.2 ± 35.8 sec two hours after initiating argatroban. At this time mean argatroban concentration was 0.34 ± 0.16 and 0.61 ± 0.28 μg/ml using ECT and TT measurements, respectively. New and/or extended thromboses were reported in 25 % of patients.

Monitoring of direct inhibitors of thrombin (DTI) is critical for their safe and effective use as anticoagulants. We examined samples containing several concentrations of argatroban or lepirudin in.. Argatroban-treated patients, compared with controls, had more rapid recovery of platelet and careful monitoring is important to avoid bleeding complications. 23 Antibodies that alter the anticoagulant activity of argatroban have not been detected in patients with HIT on prolonged or repeated administration of argatroban. 24 The agents are similar in that both are generally monitored using. Argatroban infusion, anticoagulant effects are produced as plasma Argatroban concentrations begin to rise. Steady-state levels of both drug and anticoagulant effect are typically attained within 1 to 3 hours and are maintained until the infusion is discontinued or the dosage adjusted. Steady-state plasma Argatroban concentrations increase proportionally with dose (for infusion doses up to 40.

Die Steuerung der Therapie von direkten Thrombininhibitoren (DTIs) bei Patienten mit heparininduzierter Thrombozytopenie (HIT) ist entscheidend, um thromboembolische Komplikationen einerseits und Blutungen andererseits so gering wie möglich zu halten. Festgelegte Zielbereiche für das Monitoring der DTIs sind bisher nur für die aktivierte partielle Thromboplastinzeit (aPTT) verfügbar This article describes the pharmacology of approved parenteral anticoagulants. These include the indirect anticoagulants, unfractionated heparin (UFH), low-molecular-weight heparins (LMWHs), fondaparinux, and danaparoid, as well as the direct thrombin inhibitors hirudin, bivalirudin, and argatroban. UFH is a heterogeneous mixture of glycosaminoglycans that bind to antithrombin via a unique. MONITORING FOR HIT HIT can lead to life- and limb-threatening complications where a delay in diagnosis or inappropriate continuation of heparin could increase harm to the patient. These considerations suggest that routine platelet count monitoring for HIT is appropriate in at least some clinical situations, and that the greater the risk of HIT (see Table 1), the stronger the rationale for. Since aPTT monitoring is of uncertain reliability in this patient population, an alternative means of monitoring argatroban, such as ecarin clotting time and thrombin inhibitor management testing, has been suggested.

• Monitoring therapy and dosage adjustments recommendations should be followed (2.2) • See special dosing recommendations for hepatic and renal impaired patients (2.3) -----DOSAGE FORMS AND STRENGTHS-----Argatroban Injection is supplied as a single use vial containing 125 m Routine monitoring of argatroban drug levels is not indicated, the recommended monitoring per product guidelines is with the activated partial thromboplastin time. Argatroban concentration may be affected by drug interactions, liver and renal disease. Marked presence of lipemia or bilirubin in the sample could falsely decrease argatroban levels. Supportive Data. The lower limit of detection of. Conclusions: The argatroban rates documented in this study are 50-75% less than 2-4 mcg/kg/min usually reported in literature. In addition, the conversion from aPTT to DTI monitoring resulted in a greater than 60% reduction in argatroban rates. However the correlation was also stronger at these lower rates. Although there was not a high percentage of bleeds with INR's greater than 4.0. Argatroban Order Set for Heparin-Induced Thrombocytopenia (HIT) or suspected HIT Patient weight = _____kg Page 1 of 4 A clinical pharmacist will monitor all patients on Argatroban.

Coagulation monitoring during Argatroban is the most important point. Argatroban effects are currently monitored by aPTT (activated partial thromboplastin time) with a target range from 1.5 to 3.0 times the baseline values. Closed aPTT monitoring is expected to be checked 2 h after starting infusion to avoid excessive anticoagulation and bleeding complications. The dose will be increased by 0. Monitoring Therapy: For use in PCI, therapy with Argatroban Injection is monitored using ACT. Obtain ACTs before dosing, 5 to 10 minutes after bolus dosing, following adjustments in the infusion rate, and at the end of the PCI procedure. Obtain additional ACTs every 20 to 30 minutes during a prolonged procedure A recent report showed that elevated factor VIII levels can affect aPTT monitoring of argatroban administration. 26. Modifications of the thrombin time have been proposed for anticoagulation monitoring for many years but have not been widely adopted. One of the first (which used a fibrinogen solution to dilute the patient's plasma) was called the quantitative thrombin time. 27 Other.

Argatroban is also recommended in patients with renal insufficiency because it is not cleared or adjusted renally. Dosing and titrating argatroban . When initiated, argatroban should be dosed the same in those with HITT and isolated HIT. Standard dosing is 2 mcg/kg/minute continuous IV infusion with no loading dose (unless the patient has hepatic impairment which uses lower doses). Before the. Argatroban is a direct thrombin inhibitor synthesised to bind to the catalytic site of the thrombin molecule. It binds rapidly and reversibly to both clot-bound and soluble thrombin. The relatively short elimination half-life of argatroban (39 to 51 minutes) and its reversible binding allow rapid achievement of therapeutic effect on initiation of therapy and rapid restoration of normal. monitoring argatroban.? In these situations, an actual argatroban level should be used for anticoagulation monitoring.? ? When switching from DTI to warfarin, a Chromogenic factor X can be used to monitor warfarin effect without interference by the DTI. Day(s) Performed.
