Title: Innovations by Lei Yin in Ophthalmic Drug Development

Introduction

Lei Yin is a notable inventor based in Hefei, China, recognized for his contributions to the field of ophthalmic drugs. With a total of 2 patents, he has made significant strides in developing treatment processes that enhance the efficacy of eye medications.

Latest Patents

One of Lei Yin's latest patents is a treatment process for cyclosporine eye gel. This innovative process involves several steps, including the addition of carbomer to water, thorough stirring, and homogenization. After preparing the carbomer base, it undergoes moist heat sterilization and vacuum degassing. The pH of the base is adjusted to between 5.0 and 9.0 using filtered sodium hydroxide solution. The mixture of polyoxyl 35 castor oil, cyclosporin A raw material, 1,2-propanediol, and water is prepared into a clear solution under controlled temperature conditions. The final product is achieved through uniform mixing with the carbomer base and aseptic filling after filtration. This process is particularly advantageous for industrial production due to its efficient sterilization and filtration steps.

Another significant patent by Lei Yin is a dispersion process for adapalene in gel preparation. This process includes pulverizing the adapalene raw material to specific particle sizes and creating a uniform jelly matrix by heating and stirring various components. The adapalene is then emulsified at high speed and thoroughly mixed with the matrix. The resulting preparation demonstrates excellent emulsifying and dispersing effects, making it suitable for large-scale industrial applications.
