Conventional ocular drug delivery faces challenges reaching target tissues. Sustained-release systems offer improved drug concentrations and reduced injection frequency for chronic eye diseases.
Area of Science:
- Ophthalmology
- Pharmaceutics
- Biomaterials
Background:
- Conventional ocular drug delivery struggles to achieve and maintain therapeutic concentrations due to anatomical and physiological barriers.
- Chronic posterior segment ocular diseases necessitate advanced drug delivery systems to overcome these barriers for effective treatment.
Purpose of the Study:
- To review current sustained-release corticosteroid delivery systems for ocular diseases.
- To highlight the advantages of sustained-release systems in improving ocular drug delivery efficacy.
Main Methods:
- Literature review of sustained-release corticosteroid delivery systems for ocular applications.
- Discussion of challenges and advancements in ocular drug delivery.
Main Results:
- Ocular sustained-release drug delivery systems show promise in enhancing local drug concentration and prolonging therapeutic effects.
- These systems can reduce the frequency of injections, improving patient compliance.
Conclusions:
- Sustained-release systems represent a significant advancement in ocular drug delivery, particularly for posterior segment diseases.
- Further development of effective sustained-release systems is crucial for improving clinical outcomes in managing chronic ocular conditions.
