摘要 从颗粒的实际压片操作情况及所压片剂质量出发,研究了闷窒时间对健胃消食片颗粒可压性的影响。随着闷窒时间延长,颗粒温度呈下降趋势,在0~12h内温度变化范围<4.5℃,温度变化对压片机几乎无影响。在P3200高速压片机上试压闷窒时间延长6~12h内的颗粒,结果表明,随着闷窒时间延长,调片次数、主压力值、填充高度、主压力值偏差、拉冲系数、压片工评分、包衣片质量等级和碎片率均较优且无明显变化,颗粒的可压性较优且无明显变化。从而得出结论:为减少中间体库存,节约因库存过多产生的保管、维护、搬运等费用,减少因颗粒时间未到而压片机停机等待的情况,将颗粒闷窒时间由原先规定的12h以上更改为6h,是安全、可行的。
