采用国产药用辅料，运用均匀设计方法对阿司匹林分散片处方进行筛选，给出三种崩解剂或溶胀性辅料占处方的比例分别为５％，７％，５％．经过对优选处方的实验表明：崩解时间小于３ｍｉｎ，分散均匀性试验能通过７１０μｍ筛网，均达到英国药典（１９９３年版）要求；体外溶出试验表明：Ｔ５０＝１．１６１ｍｉｎ，Ｔｄ＝２．１０９ｍｉｎ，与阿司匹林普通片溶出参数比较有显著差异，分散片溶出速度快，３０ｍｉｎ内几乎全部溶出． The domestic pharmaceutical excipients were used to screen the prescriptions of aspirin dispersible tablets by uniform design method. The proportions of the three disintegrants or swelling excipients were 5%, 7% and 5% respectively. The results showed that: the disintegration time was less than 3min, the dispersion uniformity test could pass through the 710μm sieve, which met the requirements of British Pharmacopoeia (1993 edition); in vitro dissolution test showed that: T50 = 1.161min, Td = 2.109min , And aspirin common tablets dissolution parameters were significantly different, dispersible tablets dissolution speed, almost all within 30min dissolution.
