Abstract
A method of treating human patients is provided by the intrapulmonary delivery of a pharmaceutically active peptide formulation. The formulation is automatically released in an aerosolized form from a hand-held, self-contained, portable device comprised of a means for automatically releasing a measured amount of drug into the inspiratory flow path of a patient in response to information obtained from a means for measuring the inspiratory flow rate and determining the inspiratory volume of a patient. Reproducible dosing is obtained by providing for automatic release at the same inspiratory flow rate and inspiratory volume each time drug is released. The device includes a timer to enable a patient to take a drug at the same time each day. Further, overadministration of hormone formulations is avoided by providing a pre-programmed microprocessor designed to avoid overdosing.
