Abstract

La présente invention se rapporte à un procédé de fabrication d’une formulation solide gastro-résistante de principe actif à base de phénothiazine, à une formulation obtenue par ce procédé, notamment à une formulation comprenant de 20 à 80% de bleu de méthylène, par exemple sous forme de grains ou de comprimé, ainsi qu’à la formulation de l’invention pour une utilisation comme médicament, notamment dans traitement du paludisme. Le procédé de l’invention comprend (a) l’obtention de grains de principe actif à base de phénothiazine par granulation humide d’un mélange initial comprenant, en % en poids par rapport au poids total du mélange initial de 25 à 85 % de principe actif à base de phénothiazine sous forme de poudre tamisée afin d’éliminer les amas, de 1 à 5 % d’un désintégrant, de 1 à 60 % d’un diluant, et de 1 à 20 % d’un liant ; (b) un séchage des grains de principe actif à base de phénothiazine obtenus ; (c) éventuellement, l’obtention de comprimés par compression des grains de principe actif séchés à partir d’un mélange de compression comprenant en % en poids par rapport au poids total du mélange de 30 à 80 % desdits grains séchés, de 1 à 15 % d’un désintégrant, de 5 à 70% d’un diluant identique ou différent de celui utilisé à l’étape (a), et le reste étant un lubrifiant et un agent d’écoulement ; (d) un pelliculage des grains séchés ou des comprimés au moyen d’un premier agent de pelliculage ; et (e) un pelliculage gastro-résistant desdits grains pelliculés ou comprimés pelliculés obtenus à l’étape (d).
