The spectrophotometric determination of phenylpropanolamine hydrochloride in the compound tablets 分光光度法测定复方盐酸苯丙醇胺片含量
Study on pelletization technology of phenylpropanolamine hydrochloride 盐酸苯丙醇胺微丸的制备工艺研究
Phenylpropanolamine hydrochloride pellets were coated in fluid bed with Aquacoat and Surelease as coating meterial. 采用乙基纤维素水分散体(Aquacoat和Surelease)为包衣材料,以流化床设备对盐酸苯丙醇胺微丸进行包衣试验。
Phenylpropanolamine hydrochloride ( PPA) sustained release pellets were developed in fluid bed with two aqueous ethylcellulose dispersion ( Aquacoat and Surelease). Drug release characteristics in different medium pH as well as drug release mechanism from pellets were studied. 以乙基纤维素水分散体Aquacoat和Surelease为包衣材料,流化床包衣制备盐酸苯丙醇胺缓释微丸,研究微丸在不同pH介质中的释药特性和微丸释药机制。
