  • Publication number: 20250049892
    Abstract: A semaglutide soluble microneedle composition and a preparation method therefor are disclosed. The soluble microneedle composition comprises a needle material and a base material. The needle material comprises semaglutide and hyaluronidase, and a mass ratio of semaglutide to hyaluronidase is (0.05-172):1. The semaglutide and the hyaluronidase are combined to prepare the soluble microneedle composition, so that the semaglutide can be better promoted to diffuse into the systemic circulation. Compared with a semaglutide oral tablet, the soluble microneedle composition has the advantages that the blood sugar regulating effect is improved by nearly 40 times, the bioavailability of semaglutide is improved, and the dosage and the cost of the hypoglycemic drug are reduced. Moreover, the soluble microneedle technology causes no pain during use and reduces the discomforts of users.

  • Patent number: 7220433
    Abstract: The present invention is directed to parenterally-administrable microparticles for providing sustained-release of a therapeutic agent in the body, where the microparticles include a polymeric core containing a therapeutically effective amount of a therapeutic agent disposed therein, a first film encapsulating the core, the first film prepared from a first biodegradable polymer soluble in an appropriate solvent therefore, and a second film encapsulating the core and the first film, the second film prepared from a biodegradable polymer soluble in an appropriate solvent therefore, wherein the first film is insoluble in the solvent used to prepare the second film, and to parenterally-administrable compositions containing such microparticles dispersed in a suitable carrier therefore.

  • Patent number: 7101566
    Abstract: The present invention is directed to sustained release microparticle formulation for parenteral administration of biologically active substances, especially drugs. More specifically it relates to coated drug containing microparticles, wherein the coating is a synthetic, bioabsorbable, biocompatible polymeric wax that is the reaction product of a polybasic acid or derivative thereof, a polyol and a fatty acid, the polymeric wax having a melting point less than about 70° C., as determined by differential scanning calorimetry.

  • Publication number: 20060193915
    Abstract: A pharmaceutical composition for oral administration comprising a compression coated solid dosage form of a bitter or unpleasant tasting pharmaceutically active agent. Included are compression coated oral dosage forms of 3-[2-(dimethylamino)ethyl]-N-methyl-1H-indole-5-methanesulphonamide or a pharmaceutically acceptable salt or solvate thereof as active ingredient. The compression coated solid dosage forms are of use in the treatment of conditions associated with cephalic pain, in particular migraine.

  • Publication number: 20060182796
    Abstract: A pharmaceutical composition for oral administration containing a pharmaceutically active ingredient coated with an amount of a polymer combination of an enteric polymer and an ammonio methacrylate copolymer to effectively mask the taste of the medicament. In a preferred embodiment, the ratio of the enteric polymer to the ammonio methacrylate copolymer is about 40:60 to about 90:10, preferably about 60:40, by weight of polymer. The pharmaceutical coating composition is soluble in the acidic environment of the stomach, which generally has a pH value of about 1.0 to 3.0, but relatively insoluble at higher pH values of the mouth. The coatings provide for rapid release and absorption of the drug after it passes through the mouth, and is particularly desirable in the case of liquid dosage forms.
