I'm fairly new to WNL and have been using Phoenix 8.1 just recently. I've mostly worked with single-dosing using NCA.
I have tried to combine single-dosing (0-24hours) and repeated dosing data (steady-state timepoints) in one full analysis but I keep encountering this error msg "ERROR: 14061: No data in steady state dosing interval; program terminating." Although I am able to execute, I am prompted to see text output for details as final parameters could not be generated.
I have indicated tau to be 24 hours, since drug was administered once per day; continuously for 14 days.
PK Winnonlin input-Steady state.xlsx 11.39KB 243 downloads
Time points for first 24 hours are 0, 15min, 30min, 1h, 2h, 4h, 6h, 8h, 8h, 24h. Steady-state is expected after day 5. Subsequent sampling were taken at day 6, day 13 and day 20.
Can someone tell me what I'm doing wrong here?
Thanks in advance!
