摘要:
Provided herein are pharmaceutical compositions comprising an anti-inflammatory macrolide compound suitable for aerosolized administration to the lungs by inhalation, and methods of treating inflammatory lung conditions, particularly those characterized by chronic inflammation, by administering an aerosolized anti-inflammatory macrolide compound to the lungs by inhalation. Also provided are unit dose formulations of an anti-inflammatory macrolide for aerosolized administration to the lungs by inhalation. Advantageously, the described methods and compositions allow for the targeted, localized delivery of anti-inflammatory macrolide compounds throughout the lungs without significant systemic absorption or deposition.

Particles having a tap density of less than 0.4 g/cm3 include a hydrophobic amino acid or salt thereof and a therapeutic, prophylactic or diagnostic agent or any combination thereof. Preferred particles include a phospholipid, have a median geometric diameter between about 5 and about 30 microns and an aerodynamic diameter between about 1 and about 5 microns. The particles can be formed by spray-drying and are useful for delivery to the pulmonary system.

Compounds of the formula: ##STR1## are provided, in which R.sup.1 and R.sup.2 each independently represent a C.sub.8 -C.sub.24 saturated or unsaturated hydrocarbon chain, which is optionally interrupted by from 1 to 3 heteroatom moieties, such as --O--, --S--, --NH-- and --NR--. The symbol X represents --CH.sub.2 --, --O--, --S--, --NH-- or --NR--. The R group for each of the --NR-- moieties represents an alkyl group having from 1 to 4 carbon atoms. Finally, the subscript n represents the integer 1 or 2, and A.sup.- represents an anion, preferably chloride or citrate.
