Charles University, Faculty of Pharmacy in Hradci Králové Department of: Pharmaceutical technology Consultant: doc. PharmDr. Jitka Mužíková, Ph.D. Student: Thao Tranová Title of Thesis: Influence of fillers' and disintegrants' type on properties of tablets with high dose drug The work engages in the study of fillers' and extragranular superdisintegrants' influence on properties of tablets with high dose drug. Two types of granulate with lactose or microcrystalline cellulose were produced in high shear granulator. Eleven tablets groups with different type and amount of superdisintegrants were prepared from the granulates. Tablets contained 2 %, 3.7 %, 5.4 % of sodium croscarmellose or 2 % and 5.4 % of crospovidone. The tested parameters of tablets were friability, hardness, disintegration time and density. Accelerated stability studies lasting 6 months at temperature of 40 řC and relative humidity 75 % were done. The tablets were evaluated after 1.5, 3 and 6 months. All tablets had adequate friability, hardness, disintegration and density at T0. Increasing concentration of superdisintegrant decreased disintegration time. Tablets containing microcrystalline cellulose and sodium croscarmellose disintegrated faster than tablets containing lactose or crospovidone. Tablets with sodium croscarmellose had...
