In
population pharmacokinetic (PPK)
research of
Chinese medicines with narrow
therapeutic windows of
toxicity, or when the
target population is not homogeneous, or when there are frequent adverse reactions to parenterally administered
Chinese medicine, select those that have a definite
therapeutic effect, and in which the compositions of the
toxic substances compositions are known, for study, and use complete PPK sampling design to take samples at specific
time points. Use
gas chromatography,
HPLC, and
LC-MS methods for the
detection of target components. Finally, use total quantity statistical moment
analysis, to account for each component of the PPK
parameters. Thus, PPK model can reflect the overall trend of
Chinese medicine, to provide the basis for reasonable clinical
dosage adjustments.
