Abstract
The present invention refers to pharmaceutical formulations based on lipids for ophthalmic use comprising a phospholipid component composed of zwitterionic phospholipids of natural origin and an oily component composed of oils of natural origin emulsified in water. In particular, the invention refers to ophthalmic formulations useful, for example, for transporting drugs to the eye and in the treatment of ocular dryness, capable of restoring the lipid layer of the tear film. In particular, in a non-transitory but pathological situation such as the dry eye syndrome, such formulations also succeed in reducing the often-present inflammatory component.
