Therapeutic Applications of Nanoemulsion-Based Drug Delivery Systems: A Review of Patents in the Last Two Decades

The document from 2011 provides a comprehensive review of patents and therapeutic applications of nanoemulsion-based drug delivery systems from 1980 to 2010. Nanoemulsions, characterized by their small droplet size and stability, are used in various drug delivery methods, including oral, nasal, ophthalmic, parenteral, and topical routes. The review highlights patents for nanoemulsions that address a wide range of medical conditions, such as HIV, bacterial infections, neurological disorders, sleep disorders, skin conditions like acne, rosacea, UV-induced tumors, and fungal infections, as well as androgenic alopecia. It also discusses the development of nanoemulsion vaccines, including an influenza vaccine with improved stability and ease of administration. Additionally, the document covers cosmetic and dermatological applications, with patents for skin moisturizing and hair treatment formulations. The versatility and potential of nanoemulsions in therapy and diagnosis are emphasized, with a call for further research to explore their full potential in treating diseases like cancer and HIV.
