摘要:
A non-powder-form freeze-dried composition for transpulmonary administration has a disintegration index greater than or equal to 0.015 and contains at least one active ingredient. The composition becomes fine particles upon receiving air impact at an air speed greater than or equal to 1 meter/second and an air flow rate greater than or equal to 17 milliliters/second. The fine particles have a mean particle diameter less than or equal to 1×10−5 meters and/or a fine particle fraction greater than or equal to 10%. A method of making the composition, a vessel containing the composition, a method of administering the composition, a dry powder inhalation system for transpulmonary administration, and a method of transpulmonary administration are also disclosed.

摘要:
Provisions of a foam inhibitor which effectively inhibits foaming (bubbling) caused at the time of dissolving dry compositions and of a water-soluble dry composition which comprises the foam inhibitor. The form inhibitor is suitable for inhibiting foaming caused at the time of dissolving dry compositions comprising saccharide which contain a hydrophobic amino acid as essential ingredient; and the water-soluble dry composition contains pharmacologically active proteinaceous substance, saccharide and hydrophobic amino acid having the hydropathy index of about not less than 2, wherein the concentration of the hydrophobic amino acid is in the range of 0.05 wt. % to less than 40 wt. % based on the total amount of the dry composition.
