Ocular Drug Delivery System – A Review

Abstract

Background: The ocular drug delivery is a one of the challenging approaches in novel drug delivery system. The eye is the important part of the human body but it sometimes suffers with diseases or disorders due to various reasons. Depending on the type and the severity of the disease problem arise ocular drug delivery system (with suitable dosage form) used to treat eye disease and disorders. Main Body Abstract: The surface of ocular drug delivery is restricted for only some areas and it requires lower dose than systemic circulation. Due to blood flow barriers in the eye, ocular disorders are treated with medication through topical application. For this reason, it is important to understand anatomy and physiology as the drug is administered via several ways. Conclusion: In the grow up population, scientists are designing nano and micro formulation drug release to boost the bioavailability and to overcome the barriers. They are like as liposomes, nanoparticles, nano-wafers, micro-needles etc.
