Ocular Delivery

Abstract Cataract surgery interventions are constantly increasing, particularly among adult and elderly patients. This type of surgery can lead to inflammatory states of the ocular anterior segment (AS), usually healed via postoperative treatment with dexamethasone (DEX)-containing eye drops. The…

Abstract Ocular drug delivery is challenging due to the presence of tissue barriers and clearance mechanisms. Most widely used topical formulations need frequent application because of poor permeability, short retention, and low bioavailability. Invasive intraocular injections and implants that…

Recent studies have demonstrated that Sirtuin-1 (SIRT-1)-activating molecules exert a protective role in degenerative ocular diseases. However, these molecules hardly reach the back of the eye due to poor solubility in aqueous environments and low bioavailability after topical application on the…

Osthole (OST), a natural coumarin compound, has shown a significant inhibitory effect on corneal neovascularization (CNV). But, its effect on treating CNV is restricted by its water insolubility. To overcome this limitation, an OST-loaded microemulsion (OST-ME) was created to improve the drug’s…

This research work is to develop nanofiber loaded in -situ gel for the delivery of fenofibrate to the posterior ocular site. Fenofibrate had showed its efficacy in neovascular ocular diseases under clinical studies but its low aqueous solubility makes difficult to develop a suitable ocular…

Abstract The human eye is a special organ. Its defense mechanisms protect it from invading microbes and harmful molecules. Treatment of different eye diseases often shows poor results due to the presence of these barriers. Nano lipid carriers have the capability to overcome these anatomical and…
