Nonaqueous fluorinated drug delivery vehicle suspensions
First Claim
1. A low delivery volume nonaqueous pharmaceutical composition displaying the property of enhanced drug bioavailability at a physiological target site and reduced side effects, said composition comprising:
- a drop instillable mixture of a nonaqueous, physiologically acceptable perfluorocarbon liquid carrier and a pharmaceutically effective amount of a therapeutic or diagnostic compound incorporated in a particulate polymer drug delivery vehicle, said mixture having a delivery volume on the order of 10 μ

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