  • Patent number: 6303150
    Abstract: A method for producing nanocapsules with cross-linked protein-based walls, comprising preparing emulsions of said proteins and crosslinking these with a crosslinking agent having reactive groups which react with the reactive groups of said proteins, particularly acylatable groups, to cause an interfaced crosslinking reaction between the proteins and the crosslinking agent, and thereby form capsules with walls based on the proteins crosslinked by the crosslinking agent. A fine emulsion of said proteins is prepared by adjusting the surface tension of the various liquid phases. Biocompatible and biodegradable nanocapsules having improved controlled release are thereby obtained.

  • Patent number: 6214377
    Abstract: The use of melatonin for the production of peroral pulsatile forms of medications assures the safeguard of an effective level of the medical substance of melatonin in the blood, and which realize a relatively short invasion phase with a controlled delivery in comparison to conventional forms of medication containing melatonin, and which simultaneously exclude the known side effects. A control of the delivery of the melatonin is effected which is associated with the precise adaptation to the illness episodes or the pain attacks of certain illnesses, which can be treated prophylactically and therapeutically with the active agent melatonin.
