This invention discloses a compound traditional Chinese medicine powder inhaler for respiratory tract infections and its preparation method, relating to the field of pharmaceutical formulation technology. The compound traditional Chinese medicine powder inhaler for respiratory tract infections is composed of polysaccharide composite gel microspheres, forsythia, scutellaria, honeysuckle, and isatis root. The polysaccharide composite gel microspheres are composed of seaweed sulfated polysaccharide, lentinan, calcium chloride, and curcumin. Seaweed sulfated polysaccharide, lentinan, curcumin, and calcium chloride cross-link to form a three-dimensional network spherical structure, improving the particle morphology and flowability of the micropowder. Furthermore, due to its good hygroscopic and moisturizing properties, it competitively reduces the moisture absorption of the micropowder, preventing aggregation and further improving flowability. In addition, the gel microspheres have excellent adhesion, adhering to the infection site after entering the respiratory tract, reducing expulsion losses due to respiration, maintaining an effective drug concentration at the infection site, and improving therapeutic efficacy.
