dorzolamide ophthalmic drop is one of the most common glaucoma medications but it has a short residence time in the eye. the aim of this study is to develop ocular dorzolamide hcl nanoliposomes (drz – nanoliposomes) and to evaluate their potential use for the treatment of ocular hypertension. nanoliposomes were prepared using reverse-phase evaporation vesicle (rev) and thin layer hydration (tlh...

Background: Tolmetin (Tol) is a pyrrole acetic acid derivative that acts as a highly effective topical anti-inflammatory agent. Topical administration of Tol is effective for the management of ocular inflammations.The aim of this study was to formulate and improve a topical ophthalmic delivery system of Tol. Materials and methods: In the present study, ocular inserts of Tol were prepared using ...

The major challenge faced by today's pharmacologist and formulation scientist is ocular drug delivery. Topical eye drop is the most convenient and patient compliant route of drug administration, especially for the treatment of anterior segment diseases. Delivery of drugs to the targeted ocular tissues is restricted by various precorneal, dynamic and static ocular barriers. Also, therapeutic dru...

In current drug delivery scenario, despite numerous scientific efforts, efficient ocular drug delivery remains a challenge for pharmaceutical scientists. In ocular drug delivery system, ocular infections are treated by various topical drug applications in the form of solutions, suspensions and ointment. These conventional dosage forms suffer from the problems of poor ocular bioavailability due ...

Objective(s): Micelles have been studied as nanoparticulate drug delivery systems for improving the topical ocular delivery of hydrophobic drugs. The objective of this study was to develop and characterize dexamethasone-loaded polycaprolactone-polyethylene glycol-polycaprolactone (PCL-PEG-PCL) micelles to improve patient compliance and enhance the ocular bioavailability of poorly water-soluble ...
