  • Patent number: 6207178
    Abstract: The present invention is in the area of administration forms and delivery systems for drugs, vaccines and other biologically active agents. More specifically the invention is related to the preparation of suspensions of colloidal solid lipid particles (SLPs) of predominantly anisometrical shape with the lipid matrix being in a stable polymorphic modification and of suspensions of micron and submicron particles of bioactive agents (PBAs); as well as to the use of such suspensions or the lyophilizates thereof as delivery systems primarily for the parenteral administration of preferably poorly water-soluble bioactive substances, particularly drugs, and to their use in cosmetic, food and agricultural products. SLPs and PBAs are prepared by the following emulsification process: (1) A solid lipid or bioactive agent or a mixture of solid lipids or bioactive agents is melted.

  • Patent number: 6180601
    Abstract: The invention relates to freeze-dried soft, flexible and continous matrix of low-molecular weight hyaluronic acid or salt thereof, in which the molecular weight of the hyaluronic acid is preferably between 50 000 and 200 000 Da, containing at least one peptide or protein. It also relates to a pharmaceutical composition in the form of a layer which is characterised by this freeze-dried low-molecular weight hyaluronic acid containing at least one peptide or protein. The drug is preferably chosen from at least one of GH, IGF-I, IGF-II and/or EGF and could be mixtured with an antibiotic agent. The process for the manufacture of this matrix and the use of the pharmaceutical composition for the manufacturing of a drug for wound healing is claimed. The invention discloses a method for accurately obtaining a predetermined dosage of a topically administerable drug which is characterised by freeze-drying a water solution of low-molecular weight hyaluronic acid and the peptide or protein to form a layer.

  • Patent number: 6126945
    Abstract: Staphylococcal enterotoxins obtained by secretion from Staphylococcus aureus, by expression of enterotoxins in other bacteria or cells, or by chemical mutagenic treatment of Staphlococcus aureus strains are used in treatment of cancer as tumoricidal agents. Enterotoxins A, B, C, D, E and toxic shock toxin (TSST-1) can be administered via simple intravenous injection or in the form of adjuvants such as pluronic triblock copolymers. Enterotoxins may also be used ex-vivo to induce mitogenesis, enlarge and enrich a tumoricidal T-cell population. Streptococcus pyrogenic exotoxins which have structural and functional homology to the enterotoxins, are also useful in tumoricidal treatment. Chemically derivatized enterotoxins as well as synthetic or genetically prepared polypeptides having structural homology to the native enterotoxins are also useful in this application.

  • Patent number: 5772630
    Abstract: An injection cartridge is disclosed which has provision for the after injection of a rinsing solution to wash off the medicament that is first injected. The novel cartridge has a forward compartment and a rearward compartment, each having a piston disposed rearwardly thereof. A by-pass conduit is provided at the forward end of the cartridge which is longer than the thickness of the forwardmost piston. A medicament is positioned in the forward compartment and a rinsing solution is positioned in the rearward compartment. Moving the rearward piston forward forces the rinsing solution against the forward piston which in turn forces the medicament forward and expels it from the forward compartment. After the forward piston has reached its forward stop, the forward by-pass becomes open to the rearward compartment and continued forward movement of the rearward piston causes the rinsing solution to be forced through the forward by-pass and out the outlet end of the cartridge.

  • Patent number: 5753518
    Abstract: A method of determining the affinity and kinetic properties of low molecular weight ligands for their interaction with a common receptor comprises the steps of immobilizing the receptor on a sensing structure, mixing in known proportions each ligand with a ligand analogue the response of which on the sensing structure is substantially higher than that of the low molecular weight ligands, contacting each mixture with the sensing structure and measuring the response, and comparing the response of each mixture with that of the ligand analogue alone, the distortion of the ligand analogue response being representative of the affinity and kinetic properties of the ligand.
