For the galenical development, as well as for in-process controls and final controls of the product, it is necessary to know important parameters of the tablets such as the dissolution profile and breaking strength. It is useful to determine further significant parameters to support the quality ascertainment of fast-melting tablets.
The aim of the following paper was to adapt an existing method which is about the determination of the dissolution profile. Moreover, a method to diagnose the breaking strength was established. Both methods should be able to be conducted fast and easily and provide reproducible results.
The fast-melting tablets were produced according to the Lyo-Pan technique. This method is about a newly developed lyophilisation procedure, which works very economically due to the short drying times.
The methods of measurement with the texture analyser used lead to very good and highly reproducible results. The different properties of the compounds were tested and analysed. Key words Bruchfestigkeit • Galenische Entwicklung • Schmelztabletten • Texture Analyser • Zerfallszeit |
