  • Pressurized metered dose inhaler (PMDI) actuators and medicinal aerosol solution formulation products comprising therse actuators
    Publication number: 20030178022
    Abstract: The present invention relates to pressurized metered dose inhaler (pMDI) actuators having with laser-drilled orifices of novel dimensions, and to medicinal aerosol solution formulation products comprising these actuators. In particular, the present invention relates to the optimisation of the output characteristics of drug solution formulations in hydrofluoroalkanes (HFAs) by use of pMDIs with actuators with laser-drilled orifices of specific dimensions. Moreover, the actuators of the present invention allow the use of solution formulations with a high ethanol content and a high ratio of ethanol to active ingredients and thus, the use of poorly soluble active ingredients in solution formulations and allow the use of solution formulations which are substantially free of low volatility components.
