As used herein, "aerosol" can be used to refer generally to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form to an inhalable form comprising suspended solid or liquid drug particles.

[0033] As used herein, the term "atomized substrate" refers to any suitable compound or mixture of compounds that facilitates aerosol formation in use, e.g., a stable aerosol that substantially resists thermal degradation at the operating temperature of the system. Suitable atomized substrates are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as glycerol mono-, di-, or triacetate; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate.
