The present invention relates to a method of stabilizing a low molecular weight compound in a cationic liposome wherein said compound has a low , solubility in a lipid membrane and/or a low permeability across a lipid membrane. Preferably, the compound is modified in order to increase lipid membrane solubility and/or lipid membrane permeability. After delivery of the cationic liposome to a target site, particularly a target site in an organism the modification is reversed and the low molecular weight compound may enact its desired activity.
