Liposomes for Loading Hydrophobic Drugs (F10209D)

This pre-formed liposome product is created for post-loading of hydrophobic small molecule compounds into liposomes. The process of drug incorporation is very straight-forward. Then simply add an aliquot of drug solution (prepared in a water-miscible solvent such as ethanol, DMSO, etc.) into the liposome suspension. The drug molecules can be incorporated into the lipid bilayers by the nature of hydrophobic interactions. The drug solubility therefore could be significantly enhanced. Liposomal drug concentration of 1-2 mg/mL could be achieved for most lipophilic drugs. PEGylation of the liposomes provides not only better formulation stability but also the potential to achieve prolonged in vivo blood circulation. The finished drug-loaded formulations are suitable for either in vitro testing or in vivo studies.
