Hydrophilic microparticles and methods to prepare same |
| abstract |
The present invention comprises a material and a method of its preparation. The material may be described as hydrophilic microparticles, comprising a cluster of organic substance with a layer of polyelectrolyte on its surface. The present invention establishes an improved method for preparing aqueous colloidal dispersions of water-insolub le organic substances using polyionic hydrophilic polymers by which the stability of the suspension is maintained after removal of the stabilizing and/or solubilizing medium of the drug. This improved method can be utilized to formulate a variety of water-insoluble organic substances. |
