Cyclodextrin Drugs in Liposomes: Preparation and Application of Anticancer Drug Carriers.

Cyclodextrin complexes have been widely used in pharmaceutical applications, but disadvantages such as the rapid clearance of cyclodextrins from the blood stream after in vivo administration or their replacement by other molecules in the biological medium with higher luminal affinity for cyclodextrins limit the application of cyclodextrins as drug carriers. Liposome-encapsulated hydrophobic drugs have low and unstable drug loading rates. Drug-in-CD-in-liposome (DCL), which encapsulate cyclodextrin inclusion complexes into liposomes, combine the advantages of both delivery systems, can effectively avoid the leakage and rapid release of lipophilic drugs in the lipid bilayer, and help to maintain the integrity of liposomes.
