Phytosome Phytosome is a lipid-compatible molecular complex that involves two molecules (one phospholipid plus one drug). Currently, as a molecular drug delivery vehicle, the phytosome is a hybrid nanoparticle that entraps drug within SPC and is substantially similar to the lipid solubility and water solubility of the SPC, and its amphipathic characteristics promotes its transport from the surrounding water-soluble environment to the lipid-soluble environment of cancer cell membrane, thereby increasing the efficacy. Therefore, phytosome technology has significantly improved bioavailability and drug efficacy, and reduced the side effects of drugs, thus providing a fundamental advantage and breakthrough for the clinical application of certain drugs.

Phospholipid delivery nanosystems In recent years, phospholipid delivery nanosystems (PTNS) for drug delivery based on soybean phosphatidylcholine have been developed. PTNS are produced in the form of lyophilized powders, which are stable in time. The incorporation of some drugs into PTNS can greatly improve their bioavailability and therapeutic effect. PTNS contain soybean phosphatidylcholine (95-97% purity) and maltose, wherein the weight ratio of phosphatidylcholine to maltose is 1:4. After the lyophilized powder is diluted in water, PTNS nanoparticles are formed in the maltose solution.
