METHOD FOR PREPARING FILLING MATERIAL FOR PLASTIC SURGERY AND INSTRUMENTAL COSMETOLOGY, FILLING MATERIAL AND METHOD FOR INTRODUCING FILLING MATERIAL INTO PROBLEM AREA Russian patent published in 2013 - IPC A61K31/728 A61L31/14 A61P41/00 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to pharmaceutical industry, namely a method for preparing a filling material for plastic surgery and instrumental cosmetology. A method for preparing the filling material for plastic surgery and instrumental cosmetology consisting in the fact that sodium hyaluronate is prepared of cock's combs; a fraction of molecular weight 1000-2000 kDa is recovered; then sodium cations are substituted by cetylpyridinium cations; prepared hyaluronate ammonium salt is dissolved in an aprotonic solvent to produce internal esters; modified sodium hyaluronate is recovered by adding aqueous sodium chloride; sodium hyaluronate is deposited in acetone, dried and sterilised; thereafter the modified material is processed in a physiologically compatible aqueous solution to complete swelling and mechanically ground. The filling material for plastic surgery and instrumental cosmetology. The method for introducing the filling material for plastic surgery and instrumental cosmetology into problem area.

EFFECT: method enables preparing the biocompatible filling material with the pre-set physical-chemical properties.
