These microspheres are prepared by providing a solution of the polymer and of the active principal in a water-immiscible solvent which is more volatile than water and mixing with an aqueous solution of the surface-active agent, followed by evaporation of the solvent.

  • Patent number: 6120807
    Abstract: Formulations for controlled, prolonged release of GM-CSF have been developed. These are based on solid microparticles formed of the combination of biodegradable, synthetic polymers such as poly(lactic acid) (PLA), poly(glycolic acid) (PGA), and copolymers thereof with excipients and drug loadings that yield zero order or first order release, or multiphasic release over a period of approximately three to twenty one days, preferably one week, when administered by injection. In the preferred embodiment, the microparticles are microspheres having diameters in the range of 10 to 60 microns, formed of a blend of PLGA having different molecular weights, most preferably 6,000, 30,000 and 41,000. Other embodiments hare been developed to alter the release kinetics or the manner in which the drug is distributed in vivo.

  • Patent number: 6110503
    Abstract: A method for preparing biodegradable, biocompatible microparticles. A first phase is prepared that includes a biodegradable, biocompatible polymer, an active agent, and a solvent. An immiscible second phase is prepared. The first and second phases are combined to form an emulsion in which the first phase is discontinuous and the second phase is continuous. The two phases are immersed in a quench liquid that includes a quench medium and a quantity of the solvent. The quantity of the solvent is selected to control a rate of extraction of the solvent from the first phase. The first phase is isolated in the form of microparticles. Also disclosed is a microencapsulated active agent prepared by the method for preparing biodegradable, biocompatible microparticles.

  • Patent number: 6077523
    Abstract: A pharmaceutical implant for the delivery of an effective amount of a bioactive peptide or peptide analog over a period of 1 to 12 months. This implant has a diameter of about 1 to 2 mm, a length of between about 10 and 25 mm and is obtainable from a process which includes the steps of grinding a copolymer of lactic acid and glycolic acid having a ratio of glycolide to lactide units of from about 0 to 5:1 to a particle size of between about 50 and 150 .mu.m; sterilizing the ground copolymer with a dose of between about 1 and 2.5 Mrads of ionizing .gamma.-radiation; wetting the ground and sterilized copolymer with a sterile aqueous slurry of a bioactive peptide or peptide analog; aseptically blending the copolymer and the slurry to obtain a homogeneous mixture of the copolymer and between about 10 and 50% of the bioactive peptide or peptide analog; drying the mixture at reduced pressure and at temperature not exceeding 25.degree. C.

  • Patent number: 6077543
    Abstract: Methods for preparing dry powders having hydrophobic and hydrophilic components comprise combining solutions of the components and spray drying them simultaneously in a spray dryer. The hydrophilic and hydrophobic component are separately dissolved in separate solvents and directed simultaneously through a nozzle, usually a coaxial nozzle, into the spray dryer. The method provides dry powders having relatively uniform characteristics.

  • Patent number: 6074674
    Abstract: The present invention provides, inter alia, formulations useful to ameliorate symptoms associated with mucosal abrasions, specifically those due to dental orthodontic brackets; oral surgery; periodontal surgery or other procedures. For instance, there is a formulation comprising: 65 to 75% microcrystalline wax; 5 to 15% non-ionic polymer; 15 to 25% topical anesthetic; and 1 to 5% surfactant, wherein the ratio of non-ionic polymer to microcrystalline wax is no greater than 0.2. Preferably, for solid topical anesthetics, the particle size is less than the apertures of a 100-mesh screen. However, the topical anesthetic may also be a liquid. Formulations wherein the mixture is a homogeneous matrix is preferred.
