Fluoroalkyl hydrocarbons as vehicles for pharmaceutical drugs are disclosed. These vehicles are particularly well-suited for delivering drugs which are insoluble in water or chemically unstable in aqueous media. Pharmaceutical solution compositions based on these vehicles have long shelf lives and provide improved drug bioavailability. In addition, the pharmaceutical compositions of the present invention are nonaqueous, and therefore do not require preservatives or tonicity agents. The invention is particularly useful in the field of ophthalmology. |
