Method for determining drug dose for inhaled drug therapy

The invention is directed to a method for determining the total amount of liquid medicament containing an active drug substance to be aerosolized and inhaled by a patient in order to deliver a pharmaceutically effective amount (“PEA”) of said drug to the respiratory tract of said patient comprising: A) aerosolizing a measured amount of said medicament liquid containing a known amount of drug (“Aerosolized Dose”) using an aerosolization means connected to said patient via an inhalation tube and an exhalation tube; wherein said exhalation tube contains a filter means and wherein said Aerosolized Dose is less than said PEA of said drug; B) administering said aerosol to the respiratory tract of said patient via said inhalation tube; C) allowing the patient to exhale through said exhalation tube containing said filter wherein any exhaled drug is trapped on said filter; D) measuring the reflectance of the color on the filter media contained in said exhalation filter using a reflectance spectrophotometer to determine the amount of drug on said exhalation filter (“Exhaled Dose”); E) determining the actual dose delivered to said patient (“Delivered Dose”) as follows: Aerosolized Dose minus Trapped Dose minus Exhaled Dose=Delivered Dose, where the Trapped Dose is the amount of drug trapped in the inhalation tube; and F) calculating the total amount of liquid medicament to be aerosolized (“Total Aerosolized Dose”) by multiplying the PEA by the result of dividing the Delivered Dose by the Aerosolized Dose; wherein a solution or suspension of the drug is colored when viewed by the human eye or wherein the drug reacts with a reagent on the filter media of said filter means to produce a color.
