This invention relates to the field of pharmaceutical formulation technology, specifically disclosing a preparation process for sodium azulene sulfonate. The preparation process includes: adding sodium azulene sulfonate and a modified polysaccharide derivative to a solvent and stirring until completely dissolved to form a homogeneous organic phase solution; adding the organic phase solution dropwise to deionized water under stirring to form a nano-micelle dispersion; dialyzing the nano-micelle dispersion to obtain a nano-micelle solution; adding a lyophilization protectant to the nano-micelle solution and freeze-drying to obtain a lyophilized powder injection loaded with sodium azulene sulfonate. This invention solves the technical problem of low encapsulation efficiency and easy leakage of water-soluble drugs in conventional liposomes by forming a strong electrostatic complex between the amino groups in chitosan modified with uric acid and the sulfonate groups of sodium azulene sulfonate, supplemented by the hydrophobic self-assembly of uric acid, thus achieving effective encapsulation of highly water-soluble sodium azulene sulfonate. The preparation process of this invention is simple, using natural, inexpensive, and biocompatible raw materials, making it easy to scale up industrial production.
