Anticoagulation with warfarin has been used for over 60 years; however, its administration is fraught with difficulty since many factors can affect warfarin dosing.The concept of time in therapeutic range (TTR) has become a popular way to report warfarin management and compare anticoagulation management across clinical trials. WebbTR is the range of doses/concentrations at which a therapeutic agent or drug produces a therapeutic response without causing any significant adverse effect in patients. It can be measured by: TR = MEC / MTC MEC stands for minimum effective concentration, whereas MTC stands for minimum toxic concentration.
