The present invention provides a method of inhibiting growth of lung metastases in an individual comprising the steps of administering a dose of a lipid-drug enhancer liposomal complex and, in sequence, administering a dose of a lipid-anticancer drug liposomal complex. Furthermore, the lipid-drug enhancer liposomal complex may be administered in a continuing dose with the lipid-anticancer drug liposomal complex whereby both liposomal complexes are mixed in the nebulizer. Methods of inhibiting growth of lung metastases in an individual by the sequential administration via aerosolization of a dilauroylphosphatidylcholine-cyclosporin A liposomal complex and a dilauroylphosphatidylcholine-paclitaxel liposomal complex are also provided.
