[Application of beta-cyclodextrin during direct pressing of tablets].
In case of tablets prepared by direct procedure the compressibility of beta-cyclodextrin has been studied. It has been established that beta-cyclodextrin--because of its very good flowing behaviour--can successfully be applied as ingredient in direct pressing. When hardness of tablets has to be increased 20% Avicel pH 101 (VN) has been recommended. By comparative test of 1:1 mol physical mixture of chloramphenicol-beta-cyclodextrin and the granulated product it has been ascertained that method of preparation of products, behaviour of applied solid binding materials and degree of applied pressing force decisively influence the compressibility of products. Furthermore, it has been found that application of beta-cyclodextrin influences advantageously the dissolution rate of active principle from tablets.
