Simultaneous Spray Drying For Innovative Dry Powder Inhaler Combination Formulations

Spray drying, a particle engineering technique used to convert a liquid feed into a dry powder in a single, continuous step, is one of the most promising manufacturing techniques currently utilized in the pharmaceutical industry. The control spray drying allows – particularly as it relates to particle size, morphology, and stability – affords a number of advantages for inhaler formulations for pulmonary delivery. This control, coupled with new techniques pioneered to facilitate more complex combination therapies for inhalant drugs, have the potential to transform patient care for many rare and intractable diseases.
