月桂氮酮对替硝唑透皮吸收的作用

Effect of azone on penetrating absorption of tinidazole

目的：本文的研究为临床用药和配制替硝唑（ＴＮＺ）外用药选择适宜药物浓度和促进剂浓度提供依据。方法：观察ＴＮＺ对小白鼠离体皮肤的透皮吸收，比较不同药物浓度的透皮吸收量及月桂氮酮（Ａｚｏｎｅ）不同浓度的促渗作用。结果：０．２％，０．４％，１．０％ＴＮＺ，１２ｈ透皮吸收量分别为１．４１，２．８２，７．１２ｍｇ·（５０ｍｌ）－１，渗透系数分别为１２．９８×１０－６，１３．６８×１０－６，１３．７７×１０－６。促渗剂Ａｚｏｎｅ含量在５％以下时，ＴＮＺ透皮吸收百分率随着Ａｚｏｎｅ浓度的提高而增加；当Ａｚｏｎｅ含量达８％时，透皮吸收率反而下降。结论：ＴＮＺ可透过离体小白鼠皮肤，提高药物浓度可增加药物的透皮吸收量。

n this paper,penetrating absorption of tinidazole in mice skin apart from body was studied,and effects of different concentrations of tinidazole and azone on penetrating absorption of tinidazole were compared.As a result,the amount of absorption of tinidazole was obviously enhanced by increasing concentration of tinidazole and azone.The basis for clinical pharmacy and preparation of medicines for skin on selection of proper density of tinidazole and azone was established.
