Abstract
A liquid which is a perfluorinated compound whose vapor pressure at 25° C. and atmospheric pressure is greater than or equal to 10,000 Pa (100 mbar) and whose boiling point is greater than or equal to 30° C. is used in the manufacture of a pharmaceutical and/or biological composition. The pharmaceutical and/or biological composition essentially only includes this liquid and the pharmaceutical ingredient in powder form and/or the solid biological material. The pharmaceutical ingredient and/or the biological material are insoluble in the liquid. Optionally, a film-forming agent is also included.
Claims18
Use of a liquid which is a perfluorinated compound whose vapor pressure at 25° C. and atmospheric pressure is greater than or equal to 10,000 Pa (100 mbar) and whose boiling point is greater than or equal to 30° C. in the manufacture of a pharmaceutical and/or biological composition consisting essentially of:
- said liquid, and
- at least one of:
- a pharmaceutical ingredient in powder form, and
- a solid biological material,
- the at least one of the pharmaceutical ingredient the biological material being insoluble in a carrier liquid.
Pharmaceutical composition of the type comprising an active ingredient and a carrier liquid, said composition consisting essentially of:
- a carrier liquid which is a perfluorinated compound whose vapor pressure at 25° C. and atmospheric pressure is greater than or equal to 10,000 Pa (100 mbar) and whose boiling point is greater than or equal to 30° C., and
- a therapeutically active ingredient in the form of a micronized powder insoluble in the carrier liquid.
Pharmaceutical composition according to aim 8, wherein the pharmaceutical composition contains a film-forming agent.
