LIPOSOMIAL EYE DROPS SOLUTION AND USES THEREOF FOR THE TREATMENT OF DRY EYE SYNDROME

摘要

Ophthalmic formulations and uses thereof, for the treatment of dry eye syndrome, wherein an eye drops solution is composed of liposomes built with non hydrogenated phospholipids containing Linseed oil, Vitamin A Palmitate, Vitamin E TPGS and in water phase Vitamin B12 and Pycnogenol. The presence of Pycnogenols increases the antioxidant capacity in external water phase and the presence of Vitamin E TPGS increases the antioxidant effect on lipophilic phase of liposomes. The presence of Vitamin E TPGS, inside the liposomes, combined with the presence of Pycnogenol and Vitamin B12 outside the liposomes, have a protective effect (shield) against UV A/UVB rays. It is further object of the invention, a liposomal eyes drops solution as above described, containing a specific and peculiar system composed of 2-Amino-2 (hydroxymethyl) propane-1,3-diol, that act as salt forming agent for Pycnogenol (sparkly water soluble) and borate buffer, in order to improve the filterability of liposomes and have a satisfying filtration procedure to sterilize liposomial eyes drops only by filtration at 0.2 micron, avoiding the steam sterilization that would destroy the other components and liposomes structure.
