Effect of Process Change on in Vitro Release and Percutaneous Penetration of Zushima Guanjie Zhitong Gao
To investigate the effect of the production process of Zushima Guanjie Zhitong Gao from solvent method to hot-pressed method on
in vitro
kinetic behavior of this preparation.
Method
2
Solvent and hot-pressed methods were used to prepare three batches of samples above pilot scale, and
in vitro
release and percutaneous penetration of the index components (7,8-dihydroxycoumarin and methyl salicylate) in Zushima Guanjie Zhitong Gao were investigated by modified Franz diffusing cells.
Result
2
The contents of 7,8-dihydroxycoumarin and methyl salicylate in Zushima Guanjie Zhitong Gao prepared by solvent method were 73.72, 494.67 μg/patch, and their contents in hot-pressed method samples were 159.21, 2 638.99 μg/patch, respectively. In the solvent method samples, the average cumulative release amounts of 7,8-dihydroxycoumarin and methyl salicylate in 24 h were 2.04, 12.21 μg, and their average cumulative release amounts in 24 h of hot-pressed method samples were 2.16, 36.24 μg, respectively. In the solvent method samples, the average cumulative permeation amounts of 7,8-dihydroxycoumarin and methyl salicylate in 24 h were 0.38, 2.79 μg, and they were 0.40, 7.49 μg in hot-pressed method samples. The cumulative release and permeation amounts in 24 h of 7,8-dihydroxycoumarin in the hot-pressed method samples were basically the same as those of the solvent method samples, but the cumulative release and permeation amounts in 24 h of methyl salicylate in the hot-pressed method samples were significantly higher than those of the solvent method samples (
P
<
0.05).
Conclusion
2
The retention of 7,8-dihydroxycoumarin and methyl salicylate by hot-pressed method is better than that of the solvent method. The process change has no significant effect on the
in vitro
kinetics of 7,8-dihydroxycoumarin in Zushima Guanjie Zhitong Gao, however, after the change from the solvent method to the hot-pressed method, the methyl salicylate in this preparation has a higher cumulative release and permeation amounts.
