  • Publication number: 20120177698
    Abstract: The invention describes combinations of at least three amphipatic substances forming aggregate suspensions in a polar liquid. Judicious choice of system components ensures said aggregates to have extended, unusually adaptable surfaces. This is probably due to simultaneous action on said aggregates of at least two more soluble substances amongst said three system components, at least one of which is an active ingredient and preferably a drug; the third component alternatively, can take the role of a drug. The disclosure further deals with the use of said combinations in pharmaceutical preparations capable of transporting drugs into the body of warm blood creatures. This is made possible by the drug loading capability of said aggregates with the highly flexible and deformable coating, which renders the resulting drug carriers highly adaptable. The disclosure also provides methods and favourable conditions for carrier manufacturing and application.

  • Publication number: 20090155235
    Abstract: The invention describes combinations of at least three amphipatic substances forming aggregate suspensions in a polar liquid. Judicious choice of system components, which differ at least 2-times to 10-times in solubility, ensures said aggregates to have extended, unusually adaptable surfaces. This is probably due to simultaneous action on said aggregates of at least two more soluble substances amongst said three system components, at least one of which is an active ingredient and preferably a drug; the third component alternatively, can take the role of a drug. The patent further deals with the use of said combinations in pharmaceutical preparations capable of transporting drugs into the body of warm blood creatures. This is made possible by the drug loading capability of said aggregates with the highly flexible and deformable coating, which renders the resulting drug carriers highly adaptable. The patent finally reveals suitable methods and favourable conditions for carrier manufacturing and application.

  • Publication number: 20090060989
    Abstract: The invention describes novel formulations of nonsteroidal anti-inflammatory drugs (NSAIDs) based on complex aggregates with at least three amphipatic components suspended in a suitable, e.g. pharmaceutically acceptable, polar liquid medium. A suitably ionised NSAID is one of the two, amongst said three, components that tends to destabilise lipid membranes, the other system component with such activity being typically a surfactant. In contrast, the remaining amongst said at least three amphipatic components typically forms a stable lipid membrane on it's own. An essential characteristics of the resulting, relatively large, aggregates is an improved ability to penetrate pores, in a semi-permeable barrier, at least 30%, and often much smaller than the average diameter of the complex aggregate. This enables said aggregates to mediate NSAID transport through semi-permeable barriers including mammalian skin.

  • Publication number: 20080311184
    Abstract: This invention describes the principles and procedures suitable for developing, testing, manufacturing, and using combinations of various amphipatic, if necessary modified, macromolecules (such as polypeptides, proteins, etc.) or other chain molecules (such as suitable, e.g. partly hydrophobised, polynucleotides or polysaccharides) with the aggregates which comprise a mixture of polar and/or charged amphipats and form extended surfaces that can be freely suspended or supported. The described methods can be utilised for the optimisation of aggregates that, after association with chain molecules exerting some activity or a useful function, are suitable for the application in vitro or in vivo, for example, in the fields of drug delivery, diagnostics or bio/catalysis. As special examples, mixtures of vesicular droplets consisting of lipids loaded (associated) with insulin, interferon, interleukin, nerve growth factor, calcitonin, and an immunoglobulin, etc., are described.
