Methods AH dry powder inhalation was prepared by spray-drying method. Following spray-drying, resultant powders were characterized using scanning electron microscopy and laser diffraction, and the aerosolisation performance was determined using twin-stage liquid impinger. The process conditions were optimized with orthogonal design combined with multi-index test. The powder yield, aerodynamic diameter, angle of repose and respirable fraction were used as indices for orthogonal design.
