  • Nanocapsules with a polymer shell
    Patent number: 9415019
    Abstract: The invention relates to a system for administering active ingredients, including nanocapsules comprising an oil, a cationic surfactant and a polymer selected from the group consisting of polyglutamic acid (PGA), polyglutamic-polyethyleneglycol acid (PGA-PEG), hyaluronic acid (HA) and polyasparagine (PAsn) or a combination of same and, optionally, an active ingredient, with the condition that when the polymer includes polyglutamic acid or polyglutamic-polyethyleneglycol acid (PGA-PEG) the active ingredient is not a didemnin or a tamandarin. The invention also relates to methods for obtaining said nanocapsule system, the pharmaceutical compositions thereof and the use of same in medicine.

  • Nanoparticles Comprising Chitosan and Cyclodextrin
    Publication number: 20080220030
    Abstract: This invention relates to a system comprising nanoparticles designed for the release of biologically active molecules, where the nanoparticles comprise a) at least 40% by weight of chitosan or a derivative thereof and b) less than 60% by weight of a cyclodextrin or a derivative thereof, where both components a) and b) are mixed, without any covalent bond between them. This system allows for the efficient association of biologically active molecules, as well as their subsequent release in a suitable biological environment.
