Abstract: Pharmaceutical composition of memantine for administering orally which comprises a premixture comprising: i) between 74 and 85% w/w total of the premixture of a granulate of pellets comprising memantine between 10 and 15% w/w total of the premixture; coated by first coating of polyvinylpyrrolidone and a second coating comprising between 80 and 95% w/w total of the coating of cationic copolymer of dimethylaminoethyl methacrylate, butyl methacrylate and methyl methacrylate and between 5 and 20% w/w total of the coating of magnesium stearate; ii) between 4 and 7% w/w total of the premixture of sucralose; iii) between 11 and 19% w/w total of the premixture of essences. All the components have a particle size smaller than 710 microns. The composition can be a suspension, a powder for preparing a suspension or an oral disintegrating tablet. It can also be used to be administered through a nasogastric tube.

Abstract: Procedure for preparing enteric-coated pellets containing a proton pump inhibitor with benzimidazole structure, useful for preparing multi-particle pharmaceutical compositions for oral use that comprises the following stages: I) coat pure cellulose cores with a hydroalcoholic suspension that contains the proton pump inhibitor, a dibasic amino acid and polyvinylpyrrolidone; II) isolate the coated pure cellulose cores obtained in Stage I; III) apply an enteric coating to the particles obtained in Stage II above; and IV) dry the particles obtained in Stage III above and separate by size.

Abstract: Method for producing enteric microcapsules without coating, containing diclofenac or one of the salts thereof with satisfactory anti-inflammatory activity and low gastric aggressiveness; and a pharmaceutical composition containing them. The method comprises a) preparing a mixture in water-ethanol with an alginate salt, adding diclofenac or one of the salts thereof previously diluted with a surfactant and sodium bicarbonate; b) adding the previous solution to a solution with a calcium salt; c) resuspending the microcapsules obtained and isolated in an aqueous solution of the alginate salt; and d) isolating, drying and sieving through 1000 and 250 micron meshes the microcapsules obtained; and selecting the fraction comprised between both meshes. The pharmaceutical composition can be an oral composition, tablets, chewable tablets, or a powder for suspension in water.

Abstract: Pharmaceutical compositions with anti-obesity activity that act peripherally are provided, which comprise a premixture made up of pure orlistat as the active ingredient and other components that afford the premixture stability and suitable physical properties for simply preparing compositions for oral use with convenient dosage flexibility; and optionally necessary thickening, flavouring and colouring agents. A method for preparing said compositions is also provided. The orlistat content in the premixture is less than 20% of the total weight of the mass, preferably between 12 and 17%. The pharmaceutical composition can be formulated indistinctively from the premixture both as grooved tablets and powder for suspension.
