本文研究了各种聚乙二醇栓剂基质的介电常数与朴热息痛体外释放的关系及狗直肠吸收的生物利用度。介电常数的测定:用一个特定的测定器测定。该测定器通过测定标准溶液(丙酮、邻二氯苯、氯苯、氯仿、苯)的介电常数来校正。待测基质全部融熔在1立升的烧杯中,搅拌后取出250毫升放入另一个烧杯中,将此 This article studies the relationship between the dielectric constant of various polyethylene glycol suppository bases and the in vitro release of Parkinson’s disease and the bioavailability of the dog’s rectum. Determination of dielectric constant: Measured with a specific tester. The analyzer is calibrated by measuring the dielectric constant of standard solutions (acetone, o-dichlorobenzene, chlorobenzene, chloroform, benzene). The matrix to be tested is all melted in a beaker of 1 liter, 250 ml of it is taken out after stirring, placed in another beaker,
