阿昔洛韦分散片的制备

阿昔洛韦为广谱高效一线抗病毒药,但因其水溶解度小,普通片剂崩解慢,生物利用度低。我们采用水分散技术研制了阿昔洛韦分散片,崩解快,药物溶出扩散速度因其微粒分散度高的增加而提高,从而保证了它的吸收与利用。

Research on Synthesizing Disperser with Fraction of Anthracene Oil for Coal Water Slurry

Experiment of synthesizing a disperser for coal water slurry (CWS) by using fractions of anthracene oil from high-temperature coal tar was performed. The orthogonal test was used to investigate the influence of temperature, time, quantity of sulfonation agent and condensation agent and the interaction of these factors on properties of the disperser. The result shows that the influence of temperature, time, quantity of sulfonation agent and condensation agent, and the interaction of sulfonation time and sulfonation agent has a significant influence on the properties of disperser. The optimal condition of synthesis is that in 150g of the fractions of anthracene oil, 40 mL of sulfonation agent is added and sulfonated for 3 h at 130℃, then, 10 mL of condensing agent is added and condensated for 1.5 h at 115 ℃.
