A gastrointestinal stromal tumor (GIST) is a type of tumor that occurs in the gastrointestinal tract, most commonly in the stomach or small intestine.The tumors are thought to grow from specialized cells found in the gastrointestinal tract called interstitial cells of Cajal (ICCs) or precursors to these cells. gastrointestinal stromal tumor (GIST) is a type of tumor that occurs in the gastrointestinal tract, most commonly in the stomach or small intestine.
Warfarin Maintenance Dosing and INR Recall Algorithms These algorithms are intended to be used after the patient has gone through the initiation period and a chronic maintenance dose has been established. Target INR 2.5 (Range 2.0-3.0) INR â¤1.5 1.51-1.99 2.00-3.00 3.01-4.00 4.01-4.99 5.00-10.00 >10.00 Dose Change1
Thus, one way of successfully transitioning patients from argatroban to warfarin is to aim for an INR goal of approximately 4 measured at a time when the PTT is in the therapeutic range. It can then be predicted that the INR once off argatroban will be approximately 2-3, which solely reflects the influence of warfarin. However, the manufacturer warns that this linear relationship becomes unpredictable at argatroban doses exceeding 2 mcg/kg/min.
