It's passed 6 hours since the original administration of the drug. This is how you calculate its current level: Divide the time that's passed by the drug's half-life (6 / 12 = 0.5).; Raise a half to the power of the result from step 1 (0.5 0.5 = 0.707).Multiply by the …

WebAug 21, 2005 · The morning after a 15-mg dose of warfarin was given on day 3, the day 4 INR was 1.8. The WARFDOCs program projects that the steady-state dose is still 3.55 mg, and it predicts that giving just 10 mg on day 4 will result in a supratherapeutic INR of 3.3 on day 5, rising to an INR of over 7 on day 6. For example, perhaps you want to achieve a steady state of concentration (C ss) of 10 ng/mL, which requires a 30 mg dose once daily. However, it will take 10 days to achieve steady state. Assuming dose proportionality, a 60 mg dose would achieve a C ss of 20 ng/mL in 10 days also. See more There are several special PK parameters associated with steady state kinetics.
