This experimental investigation was undertaken to quantify the electrostatic charge and aerodynamic size distribution of the medicinal drug particles inhaled through an in-vitro mouth-throat (MT) in order to compare the amount of drugs can be delivered to the human lung while mimicking a patient is either sitting or lying. The MT model is a cadaver-based replica cast of human oral-pharyngeal-laryngeal region. Tested drug aerosols were generated by a commercially available metered dose inhaler (MDI). The MT model was placed inside a humidity (95%) and temperature (37oC) controlled chamber. Its mouth-inlet was positioned horizontally and vertically to simulate sitting …

The dry powder inhaler (DPI) is a popular, effective and convenient drug delivery device for inhalation therapy to treat asthma. However, a large quantity (approximately 54%) of inhaled aerosols deposit in the oropharyngeal region. Deposition in this region is undesirable because it provides minimum therapeutic benefits and has adverse localized or systemic side effects. This study reports a method of examining electrostatic charge effects on deposition of three DPI aerosols (Spiriva™ Handihaler, Advair Diskus™, and Pulmicort™ Turbohaler) in a cadaver-based cast of the human oral-pharyngeal-laryngeal (OPL) regions. Experimental aerosols were generated from the three commercially available …
