One component of the ALZT-OP drug combination is formulated as a dry powder for inhalation that requires deep lung deposition for rapid absorption in the blood stream. AZHALER-D was developed as a single dose disposable dry-powder inhalation device that facilitates the dispersion of this powder and delivers a consistent dose to the lung. The main advantages of disposable inhalers were realized by many device companies for use in treating Chronic Obstructive Pulmonary Disease, however, technical solutions did not solve problems of operation, negative human experience, and compliance. The AZHALER-D overcomes these shortcomings.
