  • Patent number: 9198833
    Abstract: The invention relates to a device for oral application of a composition. The device comprises recess having an outer rim encompassing the recess. Within the recess, a composition is arranged. The composition comprises a gelling agent and an active agent. A cover member is attached to the rim and completely covers the recess. Thus, the cover member, together with the recess, retains the composition within the recess. The cover member has an outer surface opposed to an inner surface adjoining the recess. In order to allow preparation of the composition by adding water without the risk of losing some of the composition during preparation, the cover member comprises one or more openings for providing fluidic connection between the inner surface and the outer surface. Through this opening, water can enter for preparing the composition meanwhile the cover retains all composition within the recess. The invention further relates to a method for manufacturing the device.

  • Patent number: 8715734
    Abstract: A novel process for preparing stable granulate which comprises amoxicillin trihydrate and a sugar, and to novel stable granulate comprising amoxicillin trihydrate and the sugar as well, for reconstitution with water into fine stable homogeneous aqueous suspension is described. The novel process omits preliminary process step for preparing fine particle size of micronized amoxicillin trihydrate used subsequently in the granulation process known in the art, for example grinding or micronizing of said antibiotic. In a preferred aspect of the invention the novel stable granulate comprises amoxicillin trihydrate and the sugar, preferably sucrose, free of any pharmaceutically acceptable excipient. Novel granulate, which is easily dissolved in water to form smooth aqueous suspension immediately, is used for treating bacterial infections in humans or animals, especially in pediatric patients and in the geriatrics.
