Self microemulsifying drug delivery system


A self-microemulsifying drug delivery system (SMEDDS) is a drug delivery system that uses a microemulsion achieved by chemical rather than mechanical means. That is, by an intrinsic property of the drug formulation, rather than by special mixing and handling.

The term microemulsion in self-microemulsifying drug delivery systems refers to small particles or droplets with the actual size less than 250 nm. These droplets exhibit high flexibility [37,38]. Unlike emulsions, lipid-based micro/nanoemulsions are single optically isotropic and thermodynamically stable solutions.

The primary objective of this study was to develop lipid-based self-microemulsifying drug delivery systems (SMEDDS) without using any organic cosolvents that would spontaneously form microemulsions upon dilution with water. Cosolvents were avoided to prevent possible precipitation of drug upon dilution and other stability issues. Different ...

several microns, which can be classified as Self-MicroEmulsifying Drug Delivery Systems (SMEDDS) and Self-NanoEmulsifying Drug Delivery Systems (SNEDDS). SMEDDS form transparent microemulsions with oil droplets ranging between 100 and 200 nm, while SNEDDS are more recent, with droplet sizes smaller than 100 nm [31].
