最近的研究工作表明,人们对生理适应的高分子聚合物在控释人药和兽药方面的应用有很大的兴趣。为延长治疗时间和靶向给药,一些控释系统已经成功地开发且已投放市场。制剂工业正在注意到这些系统的如下优越性:①治疗剂量可恒速释放;②治疗期间,血浓保持最佳治疗水平;③以最少频率给药;④每次剂量取得最大功效;⑤降低副作用;⑥减少或消
Recent research shows that there is great interest in the use of physiologically compatible macromolecular polymers in the controlled release of human and veterinary drugs. Some controlled release systems have been successfully developed and put on the market to extend treatment time and targeted drug delivery. The pharmaceutical industry is noticing the following advantages of these systems: (1) the therapeutic dose can be released at a constant rate; (2) blood concentrations remain optimally treated over the course of treatment; (3) the drug is administered to a minimum of frequency; (4) maximum efficacy is achieved with each dose; ; ⑥ reduce or eliminate
