An aqueous composition of latanoprost and SAE-CD is provided. The composition possesses improved stability over otherwise similar compositions excluding SAE-CD. Methods of and systems for treating disease, disorders, conditions or symptoms of the eye that are therapeutically responsive to latanoprost are also provided.

The receptor EP.sub.4 is identified as the PGE.sub.2 receptor that is most responsible enhancing the homing and engraftment of hematopoietic stem and progenitor cells. Treatment of graft sources and graft recipients with compounds that preferentially target the EP.sub.4 receptor provide effective methods of increasing engraftment success while minimizing adverse side effects that may be associated with therapies that include the use of less selective molecules such as PGE.sub.2 and dmPGE.sub.2. One effective molecule used in such therapies is 5-[(1E,3R)-4,4-difluoro-3-hydroxy-4-phenyl-1-buten-1-yl]-1-[6-(2H-tetrazol-5R-yl)hexyl]-2-pyrrolidinone or a pharmaceutically acceptable salt thereof (L-902, 688).

A dry powder inhalation treatment for pulmonary arterial hypertension includes a dose of dry particles comprising greater than 25 micrograms of treprostinil enclosed in a capsule. The dry particles can include treprostinil, a wetting agent, a hydrophobicity modifying agent, a pH modifying agent and a buffer. A method of treating a patient having pulmonary arterial hypertension includes providing a patient a dry powder inhaler, providing the patient at least one capsule for use in the dry powder inhaler, the capsule including at least 25 micrograms of treprostinil.
