CL and Vd calculations in WinNonlin [Software]
Hello all,
I have a questions regarding calculation of volume of distribution and clearance for single dose of Amphotericin B injection. Study design is open label, randomized, two-treatment, two period, two-sequence, single dose, crossover, comparative pharmacokinetic study in healthy adult human subjects under fed conditions.
Dose mode of administration is single dose of Amphotericin B liposome for injection (3 mg/kg body weight). Dose was given to subjects with respective subject weight
i.e. suppose subject No.01, weight 73 and dose 3mg/kg then total dose= 73 kg * 3 mg/kg =219 mg.
I had calculated administration VD and CL based on the non-compartmental model using IV infusion dose type. Following information’s was provided in dosing sheet in winNonlin software.
sub-1, period-1, dose-219mg, time of dose-0,
Length of Infusion-2
sub-1, period-2, dose-219mg, time of dose-0,
Length of Infusion-2.01
PK parameter calculations VD and CL values obtained from winNonlin were not matching with reference article
WinNonlin results of VD and CL is as below
sub-1, period-1, VD (mL)-29759.19, CL (mL/hr)-833.3955
sub-1, period-2, VD (mL)-82120.74, CL (mL/hr)-1029.759
Could anyone please guide me how to estimate VD and CL in mL/kg and mL/hr/kg in winNonlin software. Is there any option available to find out VD and CL in mL/kg and mL/hr/kg.
Thanks in advance
