ABSTRACT:
The invention provides crystalline forms of biphenyl-2-ylcarbamic acid 1-[2-({3-[2-(4-hydroxybenzylamino)ethylcarbamoyl]benzoyl}methylamino)ethyl]piperidin-4-yl ester, and pharmaceutically acceptable solvates thereof. The crystalline form can be a freebase (Form I or II), a salt such as a hemiedisylate salt or a heminapadisylate salt, or a solvate of a salt such as a heminapadisylate methanolate or a heminapadisylate ethanolate. The invention also provides pharmaceutical compositions comprising these crystalline compounds or prepared using these compounds; processes and intermediates for preparing the crystalline compounds; and methods of using these compounds to treat a pulmonary disorder.
