Nasal Drug Delivery System: Microemulsion As a Carrier for Intranasal Drug Delivery System Khem Chand Gupta

The novel carriers have been exploited through almost all the routes of administration. Many newer carriers are evolving with the advent of technology and the demand of targeted delivery like microemulsions. Microemulsions are clear, stable, isotropic mixtures of oil, water and surfactant. These systems are currently of interest because of their considerable potential to act as drug delivery vehicles by incorporating a wide range of drug molecules. In addition to oral and intravenous delivery, they are amenable for sustained and targeted delivery through nasal, pulmonary, vaginal and topical routes. Intranasal drug delivery system is a promising alternative route of administration for poor bioavailability drugs and it has advantages in term of increase patient acceptibility and compliance. The intent of the paper focuses on use of microemulsion technology in intranasal drug delivery along with mechanism.
