Abstract
Aerosol drug delivery devices incorporating percussively activated heat packages are disclosed. The heat packages include a percussive igniter and a fuel capable of undergoing an exothermic oxidation-reduction reaction when ignited by the percussive igniter. The drug delivery devices disclosed can be activated by an actuation mechanism to vaporize a thin solid film comprising a drug disposed on the exterior of a hat package. Metal coordination complexes of volatile drugs, and in particular nicotine, from which the drug can be selectively vaporized when heated are also disclosed. The use of aerosol drug delivery devices comprising thin films of nicotine metal salt complexes for the treatment of nicotine craving and for effecting smoking cessation are also disclosed.
