Effect of Three Chinese Herbs Processed with Different Proportions of Glycyrrhizae Radix et Rhizoma on Pharmacokinetics of Dapsone in Rats
To investigate the processing purpose of Morindae Officinalis Radix (MO)
Euodiae Fructus (EF) and Polygalae Radix (PR) processed by Glycyrrhizae Radix et Rhizoma (Gly).
Method:
2
The content of dapsone in rat plasma was determined by high performance liquid chromatography (HPLC)
the mobile phase was acetonitrile (A)-water (B) for gradient elution (0-5 min
10%-25%A; 5-20 min
25%A) and detection wavelength was set at 292 nm. PK Solution 2.0 software was used to simulate pharmacokinetic parameters.
Result:
2
Within 300 min after dapsone was administrated
compared with the control (CTL) group
the elimination of dapsone was slowed down and its plasma concentration was increased in the unprocessed product of MO (UMO) group. The elimination of dapsone was accelerated and its peak concentration (
C
max
) was decreased in the processed products of MO with Gly (GMO) groups
and they had positive correlation with proportion of Gly in GMO. Compared with the CTL group
the elimination of dapsone was slowed down
and its plasma concentration was increased and its peak time (
T
max
) was postponed in the unprocessed product of EF (UEF) group
while their
C
max
and
T
max
were changed in the processed products of EF with Gly (GEF) groups. Compared with the CTL group
the elimination of dapsone was slowed down and its plasma concentration was increased in the unprocessed product of PR (UPR) group
while the elimination was accelerated and its plasma concentration was decreased in the processed products of PR with Gly (GPR) groups.
Conclusion:
2
The elimination of dapsone is slowed down in rats administered with UMO
UEF and UPR
while its elimination is accelerated in rats administered with the processed products of these three herbs with different proportions of Gly. Among the proportions
effect of processed products of these three herbs with 100∶6 (ratio of unprocessed product-Gly) on pharmacokinetics of dapsone is not significant.
