Staccato nicotine

Staccato nicotine is an investigational inhaled nicotine therapy that uses Alexza Pharmaceuticals’ Staccato breath‑actuated thermal aerosol system to deliver excipient‑free nicotine as optimally sized aerosol particles to the deep lung for rapid systemic absorption, with a pharmacokinetic profile intended to closely mimic cigarette smoking but without combustion. The technology rapidly vaporizes a thin film of nicotine (via a thermally reversible zinc halide complex for stable film formation) to generate highly pure condensation aerosol that is absorbed through the pulmonary circulation in minutes, potentially achieving onset of action comparable to intravenous delivery while preserving smoking‑like behavioral cues such as hand‑to‑mouth action and oral inhalation to address both chemical and psychological aspects of nicotine dependence.[1][3][5][6][7]
