摘要:
The invention concerns a method of producing morphologically uniform microcapsules containing peptides, proteins or other water-soluble biologically active substances as active substance, and microcapsules produced by this method with a charging degree of between 3 and 30 wt.% and a diameter of ≤ 8 νm. According to the invention, biodegradable polymers are dissolved in a halogen-free solvent or solution mixture and the buffered active substance solution, which has a pH of between 6.0 and 8.0, is dispersed in this solution. An aqueous solution containing a surfactant is then added to this W/O emulsion (W/O/W emulsion) and the solvent removed. The microcapsules produced by this method display no tendency to agglomerate. The encapsulation efficiency of the method is between 90 and 95 %.

The use of choline or choline releasing compounds in the production of pharmacological compositions capable of reducing fatigue in a patient who has or is about to participate in major exercise by increasing acetylcholine levels in the brain or other tissues. The term "fatigue" as used herein means the subjective feeling of tiredness as well as the fatigue of muscles and the actual decrease of performance.
