临江风药(永利)

临江风药具有疏风清热,开窍豁痰,平肝熄风,镇惊止抽的作用。用于小儿急慢惊风,痰热壅盛,四技抽搐等表里实热症。其含量测定方法为以下几点:

取本品10片,精密称定,研细,精密称取适量(约相当于对乙酰氨基酚0.3g),置锥形瓶中,加稀盐酸50ml,加热回流1小时,冷至室温,加水50ml,与溴化钾3g,将滴定管尖端插入液面下约2/3处,用0.1mol/L的亚硝酸钠溶液迅速滴定,随滴随搅拌,至近终点时,将滴定管的尖端提出液面用少量的水将尖端洗涤,洗液并入溶液中继续缓缓滴定,用细玻棒蘸取溶液少许,划过涂有含锌碘化钾淀粉指示液的白瓷板上,即显蓝色条痕时停止滴定,五分钟后,再蘸取少许,如仍显蓝色条痕时,即为终点(每1ml的0.1mol/L的亚硝酸钠溶液相当于15.12mg的对乙酰氨基酚)。

本品每片含对乙酢氨基酚(C8H9NO2)应为标示量的93.0~107.0%。
