Abstract
Nonaqueous pharmaceutical compositions for use in aqueous physiological systems are disclosed comprising drug delivery suspension of nonaqueous perfluorocarbon or fluorinated silicone liquid carriers. The suspended drug may be water labile or water stable and therapeutic or diagnostic compounds which will remain stable and pharmaceutically effective for extended periods. The pharmaceutical compositions have improved bioavailability, are capable of low dose volume delivery, and do not degrade the incorporated therapeutic or diagnostic compounds making them well suited for multi-dose packaging and administration.
