Title: Shin-Ichiro Nakamura: Innovator in Pharmaceutical Preparations

Introduction

Shin-Ichiro Nakamura is a prominent inventor based in Niigata, Japan. He has made significant contributions to the field of pharmaceutical preparations, particularly in the development of innovative methods for creating solid enteric pharmaceutical formulations. With a total of 3 patents to his name, Nakamura continues to push the boundaries of pharmaceutical technology.

Latest Patents

Nakamura's latest patents include a method for preparing solid enteric pharmaceutical preparations. This method involves dissolving a cellulosic enteric base in an organic solvent, followed by mixing it with water to create a polymer solution. The organic solvent is then removed to yield a concentrate, which is combined with an anionic surfactant and dried to produce polymer powder. This powder is subsequently introduced into water to form an emulsion containing polymer particles with an average size of less than 1 µm. The emulsion is then dispersed in water with a plasticizer to create a coating liquid, which is used to coat a drug, resulting in a solid enteric pharmaceutical preparation.

Another notable patent is a method for preparing an aqueous emulsion for coating solid pharmaceuticals. This process includes dissolving a cellulosic polymer in a mixed solvent of water and an organic solvent, self-emulsifying the solution, and concentrating the resulting emulsified stock solution through ultrafiltration until the polymer concentration reaches at least 7% by weight.
