The present disclosure relates to methods for treating or preventing rejection of solid organ transplants by administering prostacyclin (PGI.sub.2) or a prostacyclin analog.

The present invention provides clinically applicable, safe and convenient, pharmaceutical compositions and methods for disease site-specific treatment. The pharmaceutical composition for disease site-specific treatment methods comprises a stealth liposome having a prostaglandin I2 receptor agonist encapsulated therein.

The present invention provides a pharmaceutical composition for use in treating an intractable heart tissue fibrosis disease accompanied by chronic heart failure. The pharmaceutical composition for use in treating an intractable heart tissue fibrosis disease accompanied by chronic heart failure comprises, as an active ingredient, at least one member selected from the group consisting of protease inhibitors, thromboxane A.sub.2 synthase inhibitors, thromboxane A.sub.2 synthase antagonists, phosphodiesterase (PDE) inhibitors, tyrosine kinase inhibitors, HMG-CoA reductase inhibitors, and antifibrotic agents. (The pharmaceutical composition includes biodegradable polymer-encapsulated, long-acting preparations thereof.)
