Méthodologie de la formulation d’une forme orale solide à libération prolongée

TL;DRAbstract

The objective of this work was the use of a formulation methodology of prolonged release dosage forms. The choice of “hydrophilic matrices” was done because of the interest and the numbered works which is devoted to it, but also for the use of a simple manufacture technology by direct compression. The selected active pharmaceutical ingredient is one of the most largely used nonsteroidial anti-inflammatory drug, the sodium diclofenac which is out of patent and used at 100 Mg per tablet. The first bibliographical part summarizes the interest of the prolonged release dosage forms, described the existing oral dosage forms and gives a progress report on the formulas and the properties of hydrophilic matrices agents among most used, in particular the cellulose ethers, hydroxypropymethylcellulose (METOLOSES®) (1). In the experimental part, we carried out the various steps necessary to the development of a prolonged release dosage form which correspond to the traditional steps of pre-formulati
