Properties
Description
This advanced engineered reference formulation features polyethylene glycol modified gadopentetate dimeglumine liposomes (NPG-PEG-Gd-DTPA). The vesicular anatomy consists of a high-purity phospholipid-cholesterol bilayer shell encapsulating the hydrophilic paramagnetic contrast agent gadopentetate dimeglumine (Gd-DTPA) within its central aqueous reservoir, whose exterior surface is modified with functionalized polyethylene glycol (PEG) polymer anchors. This precise modification introduces a dense hydrophilic steric brush layer that completely prevents physical vesicle aggregation, isolating the active heavy metal chelate complex within the core and restricting its passive leakage.
