Abstract:ObjectiveTo make the qualified Rukang Dispersible Tablets , we carried out a detailed reasearch. MethodsWith disperal uniformity, rigidity, brittleness as the targets,we compared different kind ingrents (such as different dispersants, thinners, emplastics)and preparation process(such as the control of brittleness, granularity moisture).ResultsWe chose PPVP as dispersant (by 75%), MC as rigidity by (25%),10%PPVPK30 as brittleness( by 6%), brittleness under 4kg~9kg, granularity 35 mesh, moisture under 5.0%.ConclusionThe mass trail products made accord to the best preparation meet to the legal regulations .The process is operatable,repeatable and suitable to the batch manufatury.
