Abstract
The present invention provides methods and compositions for increasing the effectiveness of photodynamic therapy ('PDT') and for reducing the duration of skin phototoxicity associated with PDT treatment. The disclosed methods generally include the administration of a lipid composition before, during, or after the administration of photosensitizers used in the PDT treatment protocol. The lipids are preferably phospholipids. It was discovered that the disclosed methods resulted in a more rapid clearance of photosensitizers from the skin and other tissue of patients, which results in a shorter period of skin phototoxicity after PDT treatment. The present invention also provides a composition which is preferably comprised of non-polar photosensitizers and phospholipids.
