-- A preformulation was developed studying the active ingredient properties and the possible excipients. Tablets were prepared by a direct compression method, considering during the process physical properties such as hardness and friability. Two formulations were developed with the same characteristics, accelerated stability studies were developed for both of the formulations using two different primary packing materials each: amber polyvinyl chloride of 250 micras and amber polyvinylidene chloride of 250/60 micras. According to the results, we carried out the manufacturing and monitoring of three industrial batches, doing stability studies for one of them, using as the primary packing for the industrial batch amber polyvinyl of 250 micras. Therefore, to demonstrate the similarity in the behaviour of our formulation, we used the factors of similitude and difference regarding a reference product, concerning the dissolution profile. Finally all the results obtained indicate that the developed formulation fulfills the parameters of the current Pharmacopeia.
