Method of treating a systemic disease
First Claim
Patent Images
1. A method of treating a systemic disease via interpulmonary administration in a patient in need thereof, which consists essentially of:
- (a) maintaining the inspiratory flow rate in the patient in a range of about 0.05 to about 2 liters per second and the inspiratory volume of the patient in the range of about 0.1 to about 5 liters; and
(b) administering to the patient, using a pressurized breath activated metered dose device, a medicinal aerosol formulation comprising (a′
) a medicament suitable for systemic absorption via aerosol delivery present in an effective amount; and
(b′
) a fluid propellant carrier for carrying and transporting said medicament at about 50 to about 2000 milliseconds for about 1 to about 4 sprays of the aerosol formulation about every 3 to 4 hours and (c′
) and a stabilizer selected from the group consisting of an amino acid, a derivative thereof, a water addition stabilizer and a mixture of any of the foregoing stabilizers.

6. A breath activated metered dose inhalation device for delivering to a person in need thereof a medicament in aerosol form for treating a systemic disease, which consists essentially of:
-
(a) a container for controlling the medicament for treating systemic disease, a fluid propellant for carrying and transporting the medicament as an aerosol and a stabilizer selected from the group consisting of an amino acid, a derivative thereof, a water addition and a mixture of any of the foregoing stabilizers, (b) a triggering means such that when triggered by the inhalation of a patient releases said propellant and the medicament from said container; and (c) a sensing means for triggering said triggering means when the inspiratory flow rate in the patient is in the range of about 0.05 to about 2 liters per second and the inspiratory flow volume is in the range of about 0.1 to about 5 liters. - View Dependent Claims (7)
