Title
(EN) SOLID ORAL DOSAGE FORMS OF GRISEOFULVIN
(FR) NOUVELLES FORMES DE DOSES SOLIDES DE GRISÉOFULVINE À USAGE ORAL
Abstract
(EN)
A taste masked solid oral discrete dosage form comprising griseofulvin, a pharmaceutical composition comprising the same and a process for the preparation thereof . The taste masked solid oral discrete dosage forms comprises a core and/or one or more coating layers The pharmaceutical suspension composition is in the form of taste masked pellets comprising griseofulvin and one or more coating layers. The process of preparation of the taste masked solid oral discrete dosage forms comprising griseofulvin, comprises the steps of reducing the particle size of griseofulvin, blending with the other excipients, granulation, extrusion- spheronization, drying and screening to obtain discrete dosage forms, said discrete dosage forms are further coated with one or more film coating layers to achieve taste masking.

L'invention concerne une nouvelle forme de dose solide discrète à usage oral avec masquage du goût contenant de la griséofulvine, une composition pharmaceutique la comprenant, ainsi qu'un procédé pour la préparer. Cette forme de dose solide discrète à usage oral avec masquage du goût comprend un cœur et/ou une ou plusieurs couches d'enrobage. La composition pharmaceutique pour suspensions se présente sous la forme de nouveaux granulés avec masquage du goût comprenant de la griséofulvine et une ou plusieurs couches d'enrobage. Le procédé de préparation de la forme de dose solide discrète à usage oral avec masquage du goût comprenant de la griséofulvine comprend les étapes de réduction de la taille des particules de griséofulvine, mélangeage avec les autres excipients, granulation, extrusion/sphéronisation, séchage et tamisage pour obtenir des formes de doses discrètes, lesdites formes de doses discrètes étant en outre enrobées avec une ou plusieurs couches d'enrobage pelliculaire afin d'assurer le masquage du goût.
