A study of compressiblity and properties of tablets from coprocessed dry binder with manntol and croscarmellose sodium for orodispersible tablets.

Charles University, Faculty of Pharmacy in Hradec Králové Department: Pharmaceutical Technology Student: Martina Kamarýtová Consultant: PharmDr. Jitka Mužíková, Ph.D. Title of the Diploma Thesis: A study of compressibility and properties of tablets from coprocessed dry binder with mannitol and croscarmellose sodium for orodispersible tablets. This thesis deals with the study of directly compressible tableting materials and tablets with Parteck® ODT, which is designed for orodispersible tablets. The effect of three lubricants on the properties of tableting materials and tablets is evaluated. Tested lubricants are magnesium stearate, calcium stearate and sodium stearyl fumarate in concentrations of 0,5 and 1 %. Flow properties, compressibility, ejection force, tensile strength and disintegration time of tablets are tested. The compressibility is evaluated by the energy profile of compression process. Lubricants did not improve the flowability of Parteck® ODT. The total energy of compression increased with compression force and highest values were at the tableting material with 0,5 % magnesium stearate. The values of plasticity decreased with compression force, highest values were at the tableting material with 0,5 % sodium stearyl fumarate. The ejection force increased with compression force, the..
