Abstract: The present invention relates to an oral pharmaceutical composition for drugs with a high dosage regimen, specifically, ion exchange resins and bulk-forming laxatives. Said composition comprises the combination of a liquid oily component and a texturizing agent, giving the composition good organoleptic properties that allow taking drugs with a high dosage regimen without the usual problems associated with their poor palatability. The invention also relates to a method for preparing said composition and to the use thereof for the treatment of various pathologies. Furthermore, the invention also relates to an adduct formed between a polyol and an ion exchange resin, to a method for preparing it, and to the use thereof to improve resin palatability.

Abstract: The present invention relates to a solid pharmaceutical cation-exchange resin composition allowing the preparation of a stable resin suspension in an aqueous vehicle and the resin being easily resuspended in the case of sediment formation. Said composition comprises hydroxypropyl methylcellulose and pregelatinized starch as functional excipients. The invention also relates to a solid form for oral administration comprising the composition, to the use thereof for the preparation of oral solid forms, and to said composition for use in the treatment of hyperkalaemia.

Abstract: The present invention relates to a type of controlled-release multilayered methylphenidate pellet that does not need to be combined with another type of pellet. It allows the maintenance of therapeutic levels in the plasma during 12 hours with a single daily dose, avoiding repeated administrations throughout the day. The controlled-release multi-layered pellet is comprised of an inert core, a first layer that contains methylphenidate and an acid buffering system, a protective layer, a layer of ethylcellulose, that performs the function of controlling the extended release of most of the methylphenidate, and a second layer of methylphenidate, that is responsible for the immediate release of the aforesaid within one hour of administration. The weight ratio between the methylphenidate present in the first active layer and the ethylcellulose is between 1.40:1 and 1.90:1. The multi-layered pellet may possibly have an external coating to protect it from erosion during processing.
