Buccal aerosol sprays or capsules using polar and non-polar solvents have
now been developed which provide zolpidem for rapid absorption through
the oral mucosa, resulting in fast onset of effect. The buccal polar
compositions of the invention comprise formulation I: aqueous polar
solvent, zolpidem, and optional flavoring agent; formulation II: aqueous
polar solvent, zolpidem, optionally flavoring agent, and propellant;
formulation III: non-polar solvent, zolpidem, and optional flavoring
agent; formulation IV: non-polar solvent, zolpidem, optional flavoring
agent, and propellant; formulation V: a mixture of a polar solvent and a
non-polar solvent, zolpidem, and optional flavoring agent; formulation
VI: a mixture of a polar solvent and a non-polar solvent, zolpidem,
optional flavoring agent, and propellant.
