| titleOfInvention | Medical sodium hyaluronate gel and preparation method thereof |
| abstract | The invention provides a preparation method of medical sodium hyaluronate gel. The method comprises the following steps: a, weighing sodium hyaluronate sterile dry powder; b, under sterile processing condition, dissolving 0.7-0.9% of an osmotic pressure adjustor and 0.11-0.33% of a buffering agent based on water for injection in the water for injection, sterilizing, degerming and filtering; c, under sterile processing condition, preparing the sodium hyaluronate sterile dry powder obtained by the step a in the degermed and filtered buffer liquor in concentration of 10-40mg/ml, and sealing; d, stirring at 0-4 DEG C for 2-6 hours; and e, packaging and sterilely packing to obtain the medical sodium hyaluronate gel. The invention further provides the medical sodium hyaluronate gel prepared by the method and a medical composition containing the gel. According to the method, sodium hyaluronate is dissolved at 0-4 DEG C, particularly, sodium hyaluronate is dissolved by using an ice-bath dissolving method, and the whole dissolving time is 2-6 hours. The quality of final product satisfies the national standard of quality, and the risk in the product production process is greatly reduced, and meanwhile, the production time and energy consumption are reduced. |
