A method of drug delivery is disclosed wherein a patient's inspiratory flow rate and inspiratory volume are simultaneously measured using a portable, hand held, device which may be electronic and battery powered or mechanical. Information obtained from the measurement is used to release into a patient's inspiratory flow path, particles of a pharmaceutically active drug. The released particles have a particle size in the rang eof from about 0.5 microns to 12 microns. The drug is released when the patient's measured inspiratory flow rate is in the range of from about 0.10 liters/second to about 2.0 liters/second, and the patient's inspiratory volume is in the range of from about 0.15 liters to about 0.8 liters. <IMAGE> |
