Resveratrol eye drops as well as preparation method and application

In some cases, the simplest, most straightforward ideas are the best. Why not develop an eye-drop based on cyclodextrin and resveratrol?  The resveratrol captured in an HPBCD inclusion complex has the advantages of simple preparation, short preparation period, no organic solvent residue, and no bacteriostatic agent. The lipoic acid added in the clathrate eye drops prepared by the invention cooperates with the resveratrol to play a better antioxidant effect so that the xerophthalmia is better relieved, and the treatment effect is achieved.

REV-0100 for Stargardt disease (a rare pediatric retinal disease)

Paul Fehlner, co-founder and CEO of reVision Therapeutics, Inc., provided an overview of our their program, REV-0100, for Stargardt disease, a rare pediatric retinal disease. REV-0100 has the potential to expand to dry age-related macular degeneration (AMD). During the session, he discussed various aspects of REV-0100, including its mechanism of action, in vivo efficacy in Stargardt mouse models, systemic safety, competitive advantage, and development timeline.
REV-0100 is sulfobutyl-ether-beta-cyclodextrin, a commonly used pharmaceutical excipient now evaluated in this orphan indication. 

Cyclodextrin-enabled nepafenac eye drops with improved absorption open a new therapeutic window

This research is close to my heart as it comes from a Hungarian collaboration on developing nepafenac eyedrops with improved absorption. The results showed that one formulation possessed better bioavailability ex vivo than Nevanac® 0.1 % suspension, while the other formulation containing only 60 % of the original dose was ex vivo equivalent with Nevanac® opening the way to nepafenac-containing eye drops with better patient compliance in the future.

Voriconazole Eye Drops: Enhanced Solubility and Stability through Ternary Voriconazole/Sulfobutyl Ether β-Cyclodextrin/Polyvinyl Alcohol Complexes

This is a wonderful example of how something known (voriconazole-CD formulation) could be turned into something innovative. Researchers from Chulalongkorn University and Iceland University developed voriconazole eyedrops which shows high mucoadhesion, sustained release, good ex vivo permeability through the porcine cornea, and no sign of irritation. The stability study revealed that VCZ eye drops provide a shelf-life of more than 2.5 years at room temperature, while a shelf-life of only 3.5 months was observed for the extemporaneous Vfend® eye drops.
