Re: Coding infusions
Hi Batul,
I have never modeled patients with different infusion rate. However I found
out this example on the ACCP website. Maybe this will be of some help to
you. I guess you need to calculate the Dose (amount=rate *time of Infu) and
enter it
http://accp1.org/pharmacometrics/cssolutionnm.htm#cs3 (Case Study # 3)
the example also mentions that ----------Infusion rate, given the infusion
rate NONMEM calculates the duration of
infusion.
So it might be something like..
ID TIME Conc AMT RATE MDV
1 0 40 20 1
1 0.5 -- 0 0 0
2 0 200 10 1
2 0.5 -- 0 0 0
3 0 400 20 1
3 0.5
The example from ACCP is as follows
C Intravenous infusion-One compartment-Single dose Study
C No.of Subjects=20, AMT=Dose100mg for 6 hr =16.7mg/hr
C Time in hrs, CONC=Plasma Concentration in ng/ml,Clearance=L/hr,Volume=L
CID TIME CONC AMT RATE MDV
1 0 0 100 16.7 1
1 0.5 94.324 0 0 0
1 1 202.81 0 0 0
1 3 428.36 0 0 0
1 5 678.33 0 0 0
1 6 590.98 0 0 0
1 8 450.33 0 0 0
1 12 233.45 0 0 0
1 15 156.33 0 0 0
1 18 86.048 0 0 0
1 24 30.676 0 0 0
1 30 11.06 0 0 0
2 0 0 100 16.7 1
2 0.5 72.945 0 0 0
2 1 154.01 0 0 0
2 3 444.39 0 0 0
2 5 622.84 0 0 0
Good Luck
