During the past 50 years, aerosol therapy with small molecules has become the mainstay for managing lung diseases such as asthma, chronic obstructive pulmonary disease, and cystic fibrosis. During the past decade, a new therapeutic paradigm has evolved-the delivery of macromolecules into the systemic circulation through the lung. Systemic pulmonary therapy with proteins and peptides resulted from major developments in dry powder drug formulations and aerosol delivery technology. These new technologies will enable the treatment of systemic disease, such as diabetes mellitus, noninvasively by means of the deep lung. Within a decade, it is likely that many medications will be administered in this way.
