盐酸川芎嗪对大鼠在体鼻粘膜吸收研究
Study on Nasal Mucosa Absorption in Vivo of Tetramethylpyrazine Hydrochloride in Rats
【摘要】 目的 :研究盐酸川芎嗪的鼻粘膜吸收特性。方法 :采用盐酸川芎嗪进行鼻腔灌流实验。结果 :随着盐酸川芎嗪的浓度增加 ,其吸收速度呈剂量依赖性增加 ;在 pH值 4.70~ 7.0 0范围内 ,随pH值的升高 ,其吸收速度逐渐增加。 结论 :盐酸川芎嗪鼻腔灌流液的 pH为 7.0 0时 ,鼻粘膜吸收最佳
【Abstract】 Objective: To investigate the characteristic of nasal mucosa absorption in vivo of tetramethylpyrazine hydrochloride (TMP HCl) in rats. Methods: The nasal circulatory perfusion test of TMP HCl was performed in rats.Results: The absorption rate constants was increased with the increasing of the concentration of TMP HCl; The absorption rate constants was increased with the elevating of pH values at the pH value range of 4.70~7.00. Conclusion:When the pH value of nasal circulatory perfusion liquid of TMP HCl is 7.00, the nasal mucosa absorption is optimal.
【Key words】 tetramethylphyrazine hydrochloride (TMP HCl); nasal circulatory perfusion test; nasal mucosa absorption; absorption rate constants;
