POWDER FORMULATION FOR TISSUE REPAIR, PREPARATION METHOD THEREFOR, AND INJECTABLE COMPOSITION FOR TISSUE REPAIR, COMPRISING SAME

WIPO Patent Application WO/2023/003384

A1

The present invention relates to a powder formulation for tissue repair, a preparation method therefor, and an injectable composition for tissue repair, comprising same, and, more specifically, to: a powder formulation, a preparation method therefor, and an injectable composition for tissue repair, comprising same, the powder formulation comprising a biocompatible copolymer, which is a copolymer of a hydrophobic biocompatible polymer and a hydrophilic biocompatible polymer and forms, in an aqueous medium, micelle-type nanoparticles with an average diameter of a specific range and/or has a ratio, of a specific level or less, of the hydrophilic biocompatible polymer to the hydrophobic biocompatible polymer, being in a powder form so as to facilitate transport, storage and handling, being readily dissolved in an aqueous medium at room temperature so as to form stable nanoparticles, and allowing collagen induction to be performed without being phagocytosed by macrophages after being introduced into the body, thereby exhibiting an excellent tissue repair effect.
