Patent

CA 2559029

For example, a method of inhibiting the coagulation of composite particles comprising lead (or leader) particles and, adhering thereto, a drug, characterized in that a surfactant, or fatty acid derivative or lipid derivative of at least one substance selected from among sugars, peptides, nucleic acids and water-soluble polymers is contained in the lead particles. Further, there is provided, for example, a process for producing composite particles composed of lead particles having a nucleic acid as drug or a drug adhering thereto, which process comprises the step of causing a nucleic acid as drug or a drug and an adhesion-competitive agent to be contained through dispersion or dissolution in a liquid wherein lead particles containing a surfactant, or fatty acid derivative or lipid derivative of at least one substance selected from among sugars, peptides, nucleic acids and water- soluble polymers are dispersed so that not only the nucleic acid as drug or the drug but also the adhesion-competitive agent adheres to the lead particles.

L'un des aspects de l'invention concerne un procédé pour empêcher la coagulation de particules composites comprenant des particules de plomb et un médicament adhérant à celles-ci, caractérisé en ce qu'un tensioactif, ou un dérivé d'acide gras ou un dérivé de lipide d'au moins une substance sélectionnée parmi des sucres, peptides, acides nucléiques et polymères solubles dans l'eau est contenu dans les particules de plomb. Un autre aspect de l'invention concerne un procédé de fabrication de particules composites contenant des particules de plomb et un acide nucléique comme médicament ou comme médicament adhérant à celles-ci, lequel procédé consiste à disperser ou à dissoudre un acide nucléique servant de médicament ou bien un médicament et un agent de compétition d'adhérence dans un liquide dans lequel des particules de plomb contenant un tensioactif, ou un dérivé d'acide gras ou encore un dérivé de lipide d au moins une substance sélectionnée parmi des sucres, peptides, acides nucléiques et polymères solubles dans l'eau sont dispersées pour que non seulement l'acide nucléique servant de médicament, ou le médicament proprement dit, mais également l'agent de compétition d'adhérence adhère aux particules de plomb.
