The effect of solubility and hygroscopicity of some tablet diluents on the disintegration of enzyme tablets was investigated. Tablets were prepared by direct compression method using sodium starch glycolate, crospovidone, croscarmellose sodium and low-substituted hydroxypropyl cellulose as super disintegrants. Lactose, dextrose, sucrose, sorbitol and calcium phosphate dibasic were selected as typical diluents in this study. They were different in solubility (sucrose, sorbitol>dextrose>dextrose>lactose>calcium phosphate dibasic) and hygroscopicity (sorbitol>sucrose>dextrose>caicium phosphate dibasic, lactose). The disintegrants accelerated differently the disintegration of the tablets prepared with different diluents in the decreasing order of calcium phosphate dibasic>lactose>dextrose>sucrose and sorbitol. These results indicate highly soluble and/or hygroscopic diluents decrease the efficiencies of super disintegrants in the enzyme tablets.
