RESEARCH ON LIPOSOMES FOR INCREASED BIOAVAILABILITY
Liposomes, vesicles enclosed by phospholipid bilayers, can solubilize water-insoluble drugs into the lipid domain of the liposomal membrane. In addition to their solubilizing capacity and biocompatibility, the structural and compositional similarity of liposomes with bio-membranes has also encouraged their application for non-invasive oral delivery of poorly-permeable nutrients. 2
Liposomes are non-toxic, biocompatible, biodegradable, and have the following advantages as carriers in drug delivery: first, liposomes can reduce toxicity; second, hydrophilic and lipophilic agents can be incorporated into liposomes; third, liposomes control the drug release; and fourth, the liposome delivery system increases bioavailability. 3
Molecules with very poor water solubility usually have the worst bioavailability and can benefit the most from liposomal delivery. Fisetin is one example shown below up to 27x more bioavailable.
