In order to develop a novel lung targeting drug delivery system (LTDDS) with large-sized liposomes containing paclitaxel (PTX), the liposomes composed of PTX, phosopholipon 90H and tween-80 were prepared by the effervescent dispersion technique with optimal formulation composition. The liposomes were found to be relatively uniform in particle size ($8.166{\pm}0.459{\mu}m$) with a negative zeta-potential ($-12.45{\pm}1.34mv$), and high entrapment efficiency ($92.20{\pm}2.56%$). They kept stable for at least 3 months and exhibited a slow release behavior without any hemolysis reaction. Via intravenous administration in rabbits, the PTX liposomes presented a longer mean residence time and elimination half-life, and a much larger area under the plasma drug concentration-time curve compared with its injection; meanwhile, the liposomes altered its biodistribution and exhibited a significant lung targeting characteristic. For example, the relative intake rate (Re) and the ratio of peak concentration (Ce) of lung were 14.87 and 26.44, respectively. Compared with heart, liver, spleen and kidney, the ratios of targeting efficacy $(Te)_{liposomes}$ to $(Te)_{injection}$ of lung were increased by a factor of 20.08, 11.10, 6.97 and 14.41, respectively. To sum up, the liposome could be a promising drug carrier for PTX as LTDDS for lung cancer treatment.
