补充资料:磷酸氢钙片
【通用名称】
磷酸氢钙片
【其他名称】
磷酸氢钙片 磷酸氢钙片 拼音名:Linsuan Qinggai Pian 英文名:Calcium Hydrogen Phosphate Tablets 书页号:2000年版二部-1073 本品含磷酸氢钙(CaHPO4.2H2O)应为标示量的92.5%~107.5%。
【性状】
本品为白色片。
【鉴别】
取本品的细粉适量(约相当于磷酸氢钙1g),加稀盐酸 5ml、水10ml,加热使磷酸氢钙溶解,冷却,滤过,滤液显钙盐与磷酸盐 (附录Ⅲ)的鉴别反应。
【检查】
除崩解时限外,应符合片剂项下有关的各项规定(附录Ⅰ A)。
【含量测定】
取本品20片,精密称定,研细,精密称取适量(约相 当于磷酸氢钙0.6g),加稀盐酸10ml,加热使磷酸氢钙溶解,冷却,置100 ml量瓶中,加水稀释至刻度,摇匀,用干燥滤纸滤过,精密量取续滤液10ml, 加水50ml,精密加入乙二胺四醋酸二钠滴定液(0.05mol/L)25ml,加热数分 钟,放冷,加氨-氯化铵缓冲液(pH10.0)10ml与铬黑T指示剂少许,用锌滴 定液(0.05mol/L)滴定至溶液显紫红色,并将滴定结果用空白试验校正。每 1ml乙二胺四醋酸二钠滴定液(0.05mol/L)相当于8.605mg的CaHPO4.2H2O。
