    摘要: Liquid aerosol formulations for generating cromolyn sodium aerosols include at least one high volatility carrier and an optional additive such as a surfactant and/or low volatility liquid. In some embodiments, the liquid aerosol formulation is propellant free. An aerosol generating device generates an aerosol by passing liquid aerosol formulation through a flow passage heated to convert at least some of the liquid into a vapor, which is mixed with air to form an aerosol. In some embodiments, particles of the aerosol consist essentially of the cromolyn sodium or cromolyn sodium in combination with an additive such as a surfactant and/or low volatility liquid. The aerosol generator can be incorporated in a hand held inhaler and the aerosol can be delivered to a targeted portion of the lung using the inhaler for treatment of asthma.
