Evaluation of flow properties, compressibility and tablet properties of mixtures containing microcrystalline cellulose and TRI-CAFOS ® 200-7.

Charles University, Faculty of Pharmacy in Hradec Králové Department of: Pharmaceutical Technology Consultant: PharmDr. Petra Svačinová, Ph.D. Student: Daniel Višňovský Title of Thesis: Evaluation of flow properties, compressibility and tablet properties of mixtures containing microcrystalline cellulose and TRI-CAFOS ® 200-7 Direct compression technology has simplified the tabletting process by allowing immediate compression of tablets without the need of granulation. However, this applies high demands on the tableting mixture. In particular, the excipients must exhibit good compressibility and excellent flow properties. Lubricants are important for influencing these properties, but may ultimately have a negative effect on the properties of the tablets. Due to its structure and properties, Tri-Cafos ® 200-7 is a material that could be used as a lubricant. The main task of this work was the evaluation of Tri-Cafos® as a lubricant in tableting. Magnesium stearate was used as a reference substance. In mixtures with microcrystalline cellulose, the flow properties were evaluated by the flow trough an orifice method and the Hausner ratio. After subsequent compression of tablets with three compression forces (5 kN, 7.5 kN and 10 kN), the compression process was evaluated using the force-displacement...
