RE: MTIME for both Single and Repeat Dose PK in NONMEM VII
Hi Donna,
Could you please provide additional details, i.e. core model code
(dataset layout and crash message)? You may need to specify the MTIMEs
for each dose given to the system which may not be practical.
This may be an opportunity for future nonmem versions, to be able to
specify MTIMEs relative to the active dose in the system. Perhaps not
feasible for SS records.
Best regards,

Subject: [NMusers] MTIME for both Single and Repeat Dose PK in NONMEM
VII
Hi All:
I have a combined single and repeat dose data set that I am trying to
model in NONMEM VII. I can model the single dose data with MTIME
successfully (tremendous improvement in fit compared to 2-COM model
without MTIME). Does anyone have any experience modeling BOTH single
and repeat dose data with MTIME?? I have tried using 2 MTIME's (one for
single and one for the repeat dose data, but it crashes). Any
suggestions would be helpful.
Thanks much
Donna
