在检验工作中,由于操作上的一些细小环节,如辅料提取不完全或指示剂的原因等影响检测,改进后得到满意的效果。 1 辅料的影响 丙酸倍氯米松气雾剂,为肾上腺皮质激素类药。用于支气管哮喘。制剂中为增加口腔粘膜的透过性,加入吸收促进剂——油酸。 油酸为无色或浅黄色油状液体,实验证明在235nm波长处有最大吸收。 在药典丙酸倍氯米松气雾剂的丙酸倍氯米松鉴别反应中,首先将药瓶内抛射剂气化挥尽,水浴上除尽残留的抛射剂。加环已烷3ml洗涤内容物,过滤,瓶内和滤纸上的残留物
In the inspection work, due to the operation of some small links, such as excipient extraction incomplete or indicator of the impact of detection, improve and get satisfactory results. Effect of 1 excipient Beclomethasone propionate aerosol for the adrenal cortical drugs. For bronchial asthma. Formulation to increase the permeability of oral mucosa, adding absorption enhancer - oleic acid. Oleic acid is colorless or light yellow oily liquid, experiments show that the maximum absorption at 235nm wavelength. In the Pharmacopoeid beclomethasone propionate beclomethasone propionate discrimination reaction, the first vaporizer vaporizer exhausted, the water bath to remove residual propellant. Add 3 ml of cyclohexane to wash the contents, filter, bottle and filter residue
