Abstract
A method for improvement of tolerance for therapeutically effective agents delivered by inhalation comprising a pretreatment of a patient with a nebulized lidocaine or a lidocaine-like compound administered immediately or up to about thirty minutes before administration of the primary therapeutically effective agent. The pretreatment of the patient with the nebulized lidocaine or a lidocaine-like compound improves airway tolerance and deposition of the agent in the lungs and makes such deposition more safe, efficacious, controllable and predictable. The method of the invention is especially useful for enhancement of deposition of immunosuppressive agents in the lung(s) of transplant patients, improved tolerance of the drugs by reducing cough, and improving pulmonary drug deposition.
