The present invention provides propellant formulations for non-pharmaceutical use in dispersing insoluble particles having biological activity, such as bacterial spores and/or biological analogues, using a dispersion device such as a metered-dose inhaler. It is preferred that the propellant formulations of the present invention are chemically compatible with the biological analogues with which they are to be used, have substantially the same specific gravity as the biological analogues, and have sufficient vapor pressure to prevent agglomeration of the biological analogues. Methods of dispersing said biological analogues in accordance with the present invention are also provided.
A propellant formulation for dispersing a plurality of insoluble particles, said particles having biological activity, for non-pharmaceutical uses, said propellant formulation having a specific gravity substantially the same as that of the plurality of insoluble particles, said propellant formulation further being chemically compatible with said plurality of insoluble particles.
A propellant formulation for dispersing a plurality of biological analogues, said propellant formulation having a specific gravity substantially the same as that of the plurality of biological analogues, said propellant formulation further being chemically compatible with said plurality of biological analogues.
A propellant formulation for dispensing at least one biological analogue, said formulation comprising:
A propellant formulation for dispersing at least one biological analogue, said formulation having a specific gravity of 1.06 at 70 degrees Fahrenheit and a vapor pressure of 62 psia at 70 degrees Fahrenheit, said formulation being chemically compatible with said biological analogue.
A propellant formulation for dispersing at least one biological analogue, said formulation comprising:
A method of dispersing a plurality of biological analogues, said method comprising:
A propellant formulation for dispersing a biological analogue contained within a carrier, said formulation comprising, by weight:
A propellant formulation for dispersing a plurality of biological analogues contained within a carrier, said formulation comprising:
