Abstract
A method of producing positively charged liposome vesicles for use as carriers of lipophilic molecules. A mixture of hydrogenated phospholipids, a cationic excipient and a lipophilic molecule are dissolved in a solvent to form a composition. The composition is dried to remove the solvent. The dried composition is hydrated to form liposome vesicles and optionally the liposome vesicles are homogenized to form smaller vesicles. The vesicles are useful for delivery lipophilic molecules, such as, but limited to, lutein and zeaxanthin, to ocular tissues using iontophoresis.
