Percutaneous permeability study for patches Shangshi Zhitong on different kinds of bases / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the percutaneous permeability of patches Shangshi Zhitong on different kinds of bases with the permeation percentage of brucine, strychnine and atropine.</p><p><b>METHOD</b>Using modified Franz difusion to investigate the penetration quantity of brucine, strychnine and atropine. The contents of brucine, strychnine and atropine were determined by HPLC.</p><p><b>RESULT</b>The average accumulative permeation percentage of brucine, strychnine and atropine on new base were 53.25%, 74.52% were 34.32%, respectively, and on old base are 54.90%, 50.24%, 46. 54%, respectively.</p><p><b>CONCLUSION</b>The new base benefits the lipophilic drugs and releases more stably.</p>
