Abstract: The present invention relates to formulations suitable for transdermal administration characterized by containing SLNs which contain active principles with a very short half-life and/or drugs with high activity.

Abstract: The present invention refers to the use of solid lipid nanoparticles (SLN) obtained from warm microemulsions, containing cholesteryl propionate and/or cholesteryl butyrate, for preparation of a medicament for the prevention and treatment of vascular or inflammatory pathologies.

Abstract: Solid Lipid Nanoparticles of platinum compounds, particularly of antitumor platinum complexes are disclosed. The Nanoparticles of the invention are obtained by a process comprising: a) preparing a first microemulsion by mixing a molten lipid, a surfactant, and optionally a co-surfactant and the platinum compound acqueous solution; b) preparing a solution by mixing a surfactant and optionally a co-surfactant in water, heating to complete solution, preferably at the same melting temperature of the lipid used in a) and adding a co-surfactant; c) dispersing the microemulsion obtained in a) into the solution obtained in b) obtaining a multiple microemulsion c); d) dispersing the microemulsion obtained in c) in aqueous medium at a temperature ranging from 0.5° C. to 4° C.

Abstract: The invention relates to solid lipid nanoparticles composed of lipid material and containing, as bioactive molecule, a nucleic acid, preferably an antisense oligonucleotide, preferably modified by chemical methods to achieve a greater resistance to endo- and exo-nucleases, and to the process for preparation of the nanoparticles. In the present invention, the efficiency of the delivery system represented by nanoparticles containing synthetic or natural polynucleotides allows the use of such system for transfection. The particles are especially effective in the treatment of diseases of the posterior segment of the eye (such as diabetic retinopathy, macular degeneration, etc.) and in angiogenesis.

Abstract: The present invention relates to pharmaceutical compositions in form of solid lipidic nanospheres able to rapidly penetrate into the cells, comprising as an active substance a lipidic substance consisting of an ester of &agr;-tocopherol or &dgr;-tocopherol or of cholesterol or of glycerol with a carboxylic acid selected from acetic acid, propionic acid, butyric acid and succinic acid, useful in the treatment of tumoral pathologies and of Mediterranean anaemia.

Abstract: Pharmaceutical composition comprising micro particles having an average diameter ranging from 40 to 150 nm, consisting of one or more lipids, a drug and, optionally, a steric stabilizer, suitable to the transmucosal passage and to the overcoming of the blood-brain barrier and the blood-cerebrospinal fluid barrier, said micro particles being obtained dispersing in an aqueous medium cooled to 2-4° C. an oil/water or a water/oil/water micro emulsion comprising said constituents.

Abstract: A method of making a pharmaceutical composition containing a drug and solid lipidic microparticles, which are suitable for parenteral administration and resistant to phagocytosis by macrophage, is described.
