Abstract
Dry powders of .alpha.1-antitrypsin are administered pulmonarily to patients to treat, for example, certain types of emphysema. The dry powder compositions may comprise aggregates of fine particles, which aggregates are friable and break-up upon dispersion in a flowing gas stream. Typically, the dispersed powders are captured in a chamber and subsequently inhaled by a patient for pulmonary treatment of emphysema and other conditions.
