Experimental model for the evaluation of the method and regimen of inhalation therapy

: An experimental model of upper respiratory passages has been developed to be used for the choice of parameters of inhalation therapy for inflammatory processes in the larynx and evaluation of its efficiency. The model was employed to characterize "inhalation accessibility" of different segments of the upper respiratory passages and to determine the amount of a medicinal product to be delivered to the affected zone per unit time. Optimal parameters of the inhalation procedure have been derived.
