Methods and compositions for treating and preventing respiratory disorders are provided. The methods of the invention comprise administering to a subject a therapeutically effective amount of a pharmaceutically acceptable salt of an A1 adenosine receptor antagonist, particularly 1-hydroxy-2-naphthoic acid salts or 3- hydroxy-2-naphthoic acid salts, more particularly a 1-hydroxy-2-naphthoic acid salt of 3-[2-(4-aminophenyl)ethyl]-8-benzyl-7- {2-[ethyl-(2-hydroxyethyl)amino]ethyl} - 1 propyl-3,7-dihydropurine-2,6-dione (i.e., an L-97-1 xinafoic acid salt). Hydrates of the A1 adenosine receptor antagonist salts described herein are further provided. The invention further encompasses pharmaceutical compositions comprising a pharmaceutically acceptable salt of an A1 adenosine receptor antagonist in a pharmaceutically acceptable carrier. The compositions of the invention find use in methods for treating and preventing respiratory disorders.
