A recently granted patent (Publication Number: US11845811B2) discloses an improved process for the preparation of Sugammadex sodium, a pharmaceutical compound used for reversing the effects of neuromuscular blocking agents during surgery. The process involves specific steps using various organic solvents such as toluene, cyclohexane, N,N-Dimethylformamide, and others to ensure the purity of the final product. The patent also details the specific mole equivalents of reagents required and identifies known impurities that need to be controlled during the manufacturing process.
Furthermore, the patent describes the creation of a unique crystalline form of Sugammadex sodium, designated as Form-N, with specific X-ray powder diffraction patterns. This crystalline form is obtained through a precise process involving the precipitation of Sugammadex sodium from an aqueous solution using ethanol, filtration, and drying at controlled temperatures. The patent also covers the inclusion of this crystalline Form-N in a pharmaceutical composition along with a pharmaceutically acceptable carrier, highlighting its potential application in the development of new medications for clinical use.
