Design
Laboratory study
Subjects
Rat eyes given a single instillation of a PEA-loaded nanostructured lipid carrier (NLC) ophthalmic formulation; streptozotocin-induced diabetic rats for the TNF-alpha measurement
Dose used in the study
PEA-loaded nanostructured lipid carrier ophthalmic formulation, topical eye instillation
Duration
Not stated in the abstract
What was measured
Nanoparticle size, homogeneity, surface charge and physical stability; retinal distribution of PEA after instillation; retinal TNF-alpha levels in diabetic rats after topical treatment

What the authors reported

The nanostructured lipid carrier formulation delivered substantial PEA levels to the retina after a single instillation, and significantly reduced retinal TNF-alpha in streptozotocin-induced diabetic rats.

Limits of this study

A formulation and animal-model study; it cannot show effect in people, though the authors state clinical studies are in progress. The authors declare no conflict of interest.
