However, vancomycin CL and
volume of distribution were lower compared to other ICU populations due to differences in patients' demographic and clinical parameters.
Ka indicates absorption rate constant; Vz/F,
volume of distribution of fentanyl; Clparent2met, clearance of fentanyl by metabolism to norfentanyl; V2,
volume of distribution of norfentanyl; Clparent, clearance of fentanyl by all other routes; Clmet, clearance of norfentanyl.
The fact that clearance (Cl) is a function, whose value depends upon
volume of distribution, and that this parameter decreased in renal damaged conditions could be the reason for decreased Cl value of levofloxacin in renal damaged ducks.
From the clinical case study (1), the reader might infer that the changes in clearance and the
volume of distribution are reduced with time, but previous pharmacokinetic investigations have found no indications for such a finding.
The
volume of distribution ([V.sub.d]) is a proportionality constant in pharmacokinetic modeling that relates the total amount of a chemical in the body to the concentration in plasma.
In horse mean +- SEM area under curve (AUC) was 25.43+-1.07 mg h mL[?] 1, steady state
volume of distribution (VDss) was 0.267+-0.014 L.kg-1, half-life (t1/2) was 8.17+-0.602 h, mean residence time (MRT) was 1.4+-0.08 and clearance (Cl) was 0.023+-0.0016 L.h- 1.kg[?] 1 These pharmacokinetic parameters were comparable to the reported values in horse which were VDSS was 0.27+ .06Lkg[?] 1, MRT 9.6+ 3.26 hours and Cl 0.0347+ 0.0033Lh-1kg [?] 1.The respective reported means PK- values in donkeys were AUC 4.6+ 0.880mg h mL[?] 1,
The
volume of distribution at steady state (Vss), which is a sum of volumes of central and tissue compartments, is greater in febrile rabbits than in normal ones.
A 2-g dose of cefepime given intravenously results in peak serum levels of [approximately equal to] 163 [micro]g/mL with a relatively low
volume of distribution (0.29 L/kg), which would not be expected to eradicate A.
Each drug is listed with its classification, half life,
volume of distribution and normal dosage.
The fixed-effects parameters were clearance (CL),
volume of distribution of the central compartment (V1), central-peripheral clearance (Q2),
volume of distribution of the peripheral compartment (V2), central-peritoneal clearance (Q3) and
volume of distribution of the peritoneal compartment (V3).
