  • Patent number: 6953593
    Abstract: Disclosed is a process for producing sustained-release powders that is fast, efficient, and economical. The process involves melting an animal or vegetable oil with a melting point above 110 degrees F. in specially designed mixer through either the work energy input of the mixer shaft itself, or a specially fitted plow type mixer equipped with a heating tank, cooling unit, jacket for hot water circulation, and heated lines with nozzles for atomizing the hot oil to be sprayed on. The entire manufacturing process can be completed in about 5-30 minutes, and results in small, sustained-release particles that are free flowing and solid at room temperature. The preferred oil is a hydrogenated soy oil with a melting point range of 145-160 degrees F. which is applied at about a 5% level by weight in a high shear mixer. Also included are sustained-release compositions for therapeutic agents such as drugs, botanicals, biological agents, fungicides, and fertilizers.

  • Patent number: 6652865
    Abstract: A pharmaceutical composition for oral use is disclosed. It includes, as active principle, a drug liable to undergo a strong first intestinal passage effect and a carrier which is self-micro-emulsifying on contact with an aqueous phase. The carrier includes: a therapeutically effective amount of the active principle; a lipophilic phase, which is a mixture of glycerol mono-, di- and triesters and of PEG mono- and diesters with at least one fatty acid chosen from the group comprising C8-C18 fatty acids; a surfactant phase which is a mixture of glycerol mono-, di- and triesters and of PEG mono- and diesters with caprylic acid (C8) and capric acid (C10); a co-surfactant phase which is an ester of a polyvalent alcohol with at least one fatty acid chosen from the group comprising caprylic esters of propylene glycol, lauric esters of propylene glycol and oleic esters of polyglycerol. A method of decreasing the effect of intestinal metabolism on a drug using the composition is also disclosed.

  • Patent number: 6641844
    Abstract: The invention relates to carrier particles for use in pharmaceutical compositions for the pulmonary administration of medicaments by means of dry powder inhalers. In particular, the invention relates to a novel technological process for obtaining a carrier modified so as to improve the efficiency of redispersion of active particles and hence increase the respirable fraction. After the treatment of the invention, the surface of said modified carrier particles can also be coated with a suitable additive so as to further improve the respirable fraction.

  • Patent number: 6638534
    Abstract: A preparation capable of releasing a medicinal substance at a targeted site in the intestine, wherein the preparation dose not releases medicinal substance in endogastri at all, but can quickly release a medicinal substance when it reaches the desired site in the intestine after a certain period of time from discharge of the preparation from the stomach, and wherein a core material containing a medicinal substance is coated with a mixed film of a hydrophobic organic compound—an enteric polymer.

  • Patent number: RE38459
    Abstract: An injectable physiologically acceptable aqueous phase fluorocarbon emulsion, which has substantially no free fluorocarbon, has an excellent stability is prepared by a process of the invention. Typically, more than about 99.8 wt. % of the fluorocarbon remains in the size range of about 0.2 to 0.4 microns even after being stored at room temperature for one year or more in sealed containers under a non-oxidizing atmosphere. The emulsion is useful in medical applications, for example, coronary angioplasty, cancer therapy, among others.
