ABSTRACT:
Phytomedicines have a long history of therapeutic use. A wide range of phytoconstituents, including alkaloids, flavonoids, glycosides, tannins, terpenoids, peptides, carbohydrates, and lipids, have demonstrated significant therapeutic properties. The medicinal benefits of plant extracts, their separated fractions, and pure phytoconstituents have been well documented, especially through in vitro studies. However, translating these in vitro results into effective in vivo applications and successful clinical trials poses substantial challenges. These challenges include issues related to standardisation, limited efficacy against severe diseases, inconsistent biological activity, and potential interference from complex phytoconstituents, especially for ocular drug delivery applications. To address these issues, there has been a shift toward ocular drug delivery using nanoscale phytomedicine. Innovative nanotechnology-based delivery systems are being extensively researched to solve these problems. Systems that deliver various phytoconstituents at the nanoscale can improve bioavailability, minimise side effects, and reduce necessary doses. This review will focus on nanotechnology-based delivery systems for phytomedicines in different ocular therapies, with an emphasis on lipid-based nanoparticles, nanomicelles, polymeric nanoparticles, and nanostructured lipid carriers, used for a range of ocular conditions.
