sodium carboxymethylcellulose cmc-na 羧甲基纤维素钠
carboxymethylcellulose sodium cmc-na 羧甲基纤维素钠 ; 羧甲基纤维素纳
Method: GBE sustained-release tablets were prepared by direct compression method using sodium carboxymethylcellulose CMC-Na and hydroxypropyl methylcellulose HPMC as matrix excipients.
方法：以溶胀性材料羧甲基纤维素钠和羟丙甲基纤维素为骨架材料，直接粉末压片制备银杏提取物缓释片。
CMC according to different viscosity purposes can be divided into many levels, such as the viscosity of sodium carboxymethylcellulose for washing 10~70 (less than 100);
cmc根据用途的不同粘度也分很多个等级，比如洗涤类的羧甲基纤维素钠粘度为10~70（100以下）；
