Conventional delivery of antidiabetic drugs faces many problems like poor absorption, low bioavailability, and
drug degradation. Nanoemulsion is a unique drug technology which is very suitable for the delivery of antidiabetic drugs.
In recent years the flaws of delivering anti-hypoglycaemic drugs have been overcome by choosing nanoemulsion drug
technology. They are thermodynamically stable and also deliver the therapeutic agent for a longer duration. Generally,
Nanoemulsions are made up of either oil-in-water or water-in-oil and size of the droplets is from fifty to thousand
nanometer. Surfactants are critical substances which are added in the manufacturing of nanoemulsions. Only the
surfactants which are approved for human use can be utilized in the manufacturing of nanoemulsions. Generally, the
preparation of emulsions includes mixing of the aqueous phase and organic phase and using surfactant with proper
agitation. Nanoemulsions are used for antimicrobial drugs, and they are also used in the prophylaxis of cancer, diabetics.
Reduction in the droplet size may cause variation in the elastic and optical behaviour of nanoemulsions.
