Microemulsion: As Excellent Drug Delivery System
Pathan, M., Zikriya, A., Quazi, A.
Today though the oral drug delivery system is dominant still it is found to be need of ideal transdermal drug delivery system. “A micro emulsion is a system of water, oil and an amphiphile which is a single optically isotropic and thermodynamically stable liquid solution”. Microemulsions offer several advantages as drug delivery systems as these are thermodynamically stable and stability allows for self emulsification of the system with microemulsion acting as supersolvent of the drugs which are poorly or insoluble in water. They are preferred more as compared to conventional emulsions due stability. The dispersed phase mainly acts as the solvent for the water insoluble drug. Microemulsions have been proved to increase the cutaneous absorption of both lipophilic and hydrophilic API’s when compared to conventional vehicles.
