摘要:
The object of the present invention is to provide a therapeutic agent for hyperphosphatemia capable sufficiently decreasing a serum phosphorus concentration with a small dose, and particles therefor. The present invention provides a therapeutic agent for hyperphosphatemia, which comprises, as an active ingredient, a particle containing a crosslinked polymer having a substituent containing a NRA1RA2 structure or a salt thereof, wherein the particle has an average particle diameter of 20 to 150 μm and a swelling rate of 9 to 16 mL/g (wherein RA1 and RA2 each independently represent a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, an aminoalkyl group having 1 to 20 carbon atoms or a salt thereof, or the like).

摘要:
Provided are an emulsion of a nitrogen atom-containing polymer or a salt thereof, the emulsion having high emulsion stability and having a low dispersity of the particle diameter of emulsified particles, and a method for producing the emulsion. Also provided is a method for producing particles including a crosslinked nitrogen atom-containing polymer or a salt thereof by using the emulsion described above. Disclosed is a method for producing an emulsion of a nitrogen atom-containing polymer or a salt thereof, the method including a step of mixing a first solution that includes a nitrogen atom-containing polymer or a salt thereof and a hydrophilic solvent and has a viscosity of 10 to 2,000 mPa·s, and a second solution that includes a hydrophobic solvent and has a viscosity of 1 to 100 mPa·s, stirring the mixture, and thus obtaining an emulsion of the nitrogen atom-containing polymer or a salt thereof, wherein a ratio between the viscosity of the first solution and the viscosity of the second solution is in a range of 0.1:1 to 300:1.
