Inhaled insulin dosage control delivery enhanced by controlling total inhaled volume
DCFirst Claim
1. A method of administering a formulation to a human patient by inhalation, comprising:
- (a) aerosolizing a formulation comprised of a pharmaceutically active compound wherein the aerosol is comprised of particles having a diameter in a range of about 0.5 to 6.0 microns;
(b) inhaling the aerosolized formulation with a known volume of air, (c) repeating (a) and (b) a plurality of times over a period of time;
wherein the known volume of air with aerosolized formulation inhaled in each step (b) is substantially the same for each step (b) and further wherein the inhaled volume of air in step (b) is determined by the patient inhaling maximally which inhaling maximally is repeated for each step (b).

Abstract
Dosages of inhaled insulin are controlled within a narrow range by controlling the total volume of air inhaled by a patient. By repeatedly delivering aerosolized insulin with the same total inhaled volume of air, the amount of insulin delivered to the patient each time is consistent. A device for delivering insulin by inhalation is disclosed which device comprises a means for measuring inhaled volume and for halting inhalation at a pre-determined point. The device also comprises an adjustable means for applying various amounts of force to a container of formulation to expel different amounts of drug from the container based on the force applied.
