Abstract
The SeDeM diagram expert system has been applied to study Zidovudine and some excipients. From the obtained diagrams, a pharmaceutical formula has been designed. SeDeM diagram ascertains the critical parameters that are suitable for a direct compression. The formula is compressed using a rotary tablet press simulator which emulates rotary tablet press' compression profiles. From these compressions, we study the formula behavior under different industrial production conditions but saving a huge amount of material. The study is done at different compression forces and compression speeds and taking into account the influence of the pre-compression force. The differences observed between the compression profiles are hereby described. The results indicate that the formulation is able to be compressed adequately with the emulated compression profiles and no differences are observed between the final products. Therefore, we can assure that the SeDeM diagram expert system is accurate and robust. Moreover, its results are comparable with the compression results in a rotary tablet press, which has never been described in the pharmaceutical literature before. From the obtained results, it is possible to select the best rotary press to scale-up this formulation.
