摘要:
The present invention relates to pharmaceutical compositions in form of solid lipidic nanospheres able to fast penetrate into the cells, comprising as an active substance a lipidic substance consisting of an ester of α-tocopherol or δ-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.
摘要:
Solid lipid microspheres having a diameter lower than one micron and a polydispersion of between 0.06 and 0.90 obtained by adding to a molten lipid substance a mixture consisting of water, a surfactant and possibly a co-surfactant, dispersing in water the obtained microemulsion, washing with water the dispersion microspheres by diafiltration and lyophilizing.
摘要:
Pharmaceutical composition in form of solid lipidic microparticles suitable to parenteral administration containing a drug and one or more substances suitable to sterically stabilize said microparticles.
摘要:
Pharmaceutical composition comprising microparticles 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 microparticles being obtained dispersing in an aqueous medium cooled to 2-4 DEG C an oil/water or a water/oil/water microemulsion comprising said constituents.

摘要:
Pharmaceutical compositions for the treatment of ophthalmic diseases, suitable for topical ocular administration and for systemic administration, comprising solid lipid nanoparticles (SLNs) with a mean diameter comprised between 50 and 400 nm wherein, within said nanoparticles, a pharmacologically active substance for the specific ophthalmic treatment is incorporated.
摘要:
The present 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 said 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. Said 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.
