    Abstract: The present invention provides an ophthalmic composition comprising a hyperbranched polyester. The ophthalmic compositions may also comprise carbonic anhydrase inhibitors, wherein the hyperbranched polyester increases the aqueous solubility of the carbonic anhydrase inhibitor, and increases corneal permeation of the active agent. The ophthalmic compositions may also comprise non-ionic surfactants, such as PEG, Polysorbate, HPMC or HEC, and beta-blockers, such as Carteolol, Levobunolol, Betaxolol, Metipranolol, Timolol or Propranolol. The concentration of the hyperbranched polyester in the ophthalmic formulation should be less than or equal to 4% (w/v) in order to avoid any cytotoxic effects on human corneal cells and thus the eye irritation.

  • Publication number: 20120232167
    Abstract: Provided is a method of producing hydroxyalkylcellulose microparticles, the method including generating a pulse shock wave, and supplying a hydroxyalkylcellulose aqueous solution to the pulse shock wave generation region, thereby crushing and drying the hydroxyalkylcellulose aqueous solution. According to the production method, hydroxyalkylcellulose microparticles having a volume-average particle size of at least 0.1 ?m but less than 15 ?m are obtained. By mixing the hydroxyalkylcellulose microparticles with a principal agent and subjecting the resulting mixture to a tablet compression, a solid preparation having excellent tensile strength and disintegration properties can be obtained.

  • Publication number: 20120225953
    Abstract: The present invention relates to self-emulsifying formulations based on an active ingredient component and a formulation base with a lipid component and with a binder component and to the use of this formulation as dosage form in the life science sector. The invention also describes a process for producing self-emulsifying formulations by mixing the formulation components to form a plastic mixture and, where appropriate, to manufacture the formulations as dosage form advantageously by use of melt extrusion. The formulations spontaneously form emulsions in water or aqueous media.
