Pharmaceutical Nano emulsion as a Rational Carrier for Drug Delivery

Nanoemulsions are transparent system mostly covering droplet size in nanometric scale because of their small droplet sizes. Nanoemulsion appears transparent and is kinetically stable. The long term physical stability of nanoemulsion makes them unique and is sometime referred as ‘Approaching Thermodynamic stability’. These increases the rate of absorption eliminates variability in absorption and increase bioavailability. These can carry lipophilic and hydrophilic drugs. This review aims on the method of preparation, characterization techniques, advantages and disadvantages and the various route of drug delivery of nanoemulsion.
