health effects of delivering large doses of insulin deep in the lung, however, are unknown. Only 20% to 30% of the inhaled dose is absorbed into the pulmonary bloodstream, whereas 70% to 80% is metabolized within the alveoli and bronchi. Clinical trials have revealed a mild decrease in lung function (forced expiratory volume and lung volume), increase in insulin antibodies and increase in the incidence of pulmonary thromboses (43).
