Abstract: PURPOSE: A cationic phospholipids liposome containing 1,2-dioleoyl-sn-glycero-3-ethyl phosphocholine(DOPC) and sterol compounds is provided to enhance drug delivery efficiency and to remarkably reduce cytotoxicity. CONSTITUTION: A composition for lung-specific drug delivery comprises a cationic phospholipids nanoparticles containing 1,2-dioleoyl-sn-glycero-3-ethyl phosphocholine(DOPC) and sterol compounds. The sterol compounds are 3b-[N-(N',N'-dimethylaminoethane)-cabamyl]cholesterol(DC-Chol), stigmasterol, campesterol, sitosterol, ergosterol, lanosterol, dinosterol, gorgosterol, avenasterol, saringosterol, or fucosterol. The drug is anticancer drug.
