摘要
Provided is a dry powder for inhalation formulation comprising salmeterol xinafoate, fluticasone propionate and tiotropium bromide, as pharmaceutically active ingredients, and a carrier, and an inhalation formulation comprising same. The inventive dry powder inhalation formulation having good content uniformity and showing small changes in the aerodynamic size distribution in accordance with the flow rate changes can effectively deliver said pharmaceutically active ingredients to a target site upon administration, and thus can be useful in the prevention or treatment of respiratory diseases, particularly asthma and COPD.
