Nutritional compositions delivered in vivo in a time controlled manner sustainable over long periods of time, provide enhancing athletic performance, increased hand/eye coordination and concentration on the task at hand.
摘要:
Compositions for the selective delivery of an agent comprising an uncrosslinked starch modified by an acidic group and an agent are described. The compositions are substantially resistant to degradation and thus result in no or substantially no release of the agent in a first environment, and are capable of degradation in a second environment thereby allowing release of the agent. The pKa of the acidic group of the uncrosslinked starch used is higher than the pH of the first environment and lower than or equal to the pH of the subsequent environment. Also described herein are methods of preparing the compositions, methods of using the compositions and the uncrosslinked starch modified by an acidic group, and corresponding commercial packages.
摘要:
The invention relates to a method for producing pharmaceuticals or parts thereof or food supplements or parts thereof, by coating substrates for pharmaceutical uses or for using as food supplements for humans or animals, with a film-forming coating agent mixed with at least one other substance suitable for the cited purposes. The film-forming coating agent and the other substance first constitute separate liquid, sprayable individual portions, and are sprayed by means of at least one spray device - which are provided, individually or together, with at least two separate nozzles for liquids, and have overlapping spray jets - in such a way that the individual portions sprayed out of the separate nozzles mix during the spraying process and the mixture forms a continuous film coating on the substrate, forming the food supplement, the pharmaceutical or the part thereof. The invention is characterised in that the coating agent and the other substance are in a concentration gradient from the inside to the outside.
摘要:
The invention relates to a method for producing pharmaceuticals or parts thereof or food supplements or parts thereof, by coating substrates with a film-forming coating agent containing a pigment which is incompatible with the coating agent. The invention also relates to appliances for carrying out said method, especially a drum coater, a mushroom mixer, a fluidised bed appliance or a spray sifter comprising multiple spray devices.
摘要:
The invention relates to methods for producing pharmaceuticals or parts of pharmaceuticals or food supplements or parts thereof, by coating substrates with a mixture of two film-forming coating agents that can contain other pharmaceutically standard additives, especially softeners and/or a pharmaceutical active ingredient.
摘要:
The invention relates to a redispersible powder obtainable by (co)polymerization, using a polymer with cationic functionality in an aqueous medium, optionally accompanied by the use of conventional additives, the polymer with cationic functionality being obtained by (co)polymerization in an aqueous medium of olefinically unsaturated (co)monomers, wherein at least one (co)monomer has a cationic functionality, further (co)monomers are added and polymerization takes place in the presence of suitable initiators, and by drying the aqueous dispersion obtained, the (co)polymerizate having one or more reactive groups. According to another embodiment, the polymer with cationic functionality is formed in situ in the presence of a seed. According to another embodiment, the process is controlled in such a way that a (co)polymerizate particle with heterogeneous morphology is formed. The invention also relates to the aqueous dispersions, a process for the preparation of the redispersible powder and the use thereof.
