Ease of administration and painless approach made oral route the most preferred. Poor oral bioavailability is pronounced with the majority of recent active ingredients because of dissolution rate limited absorption. Failure to attain intended therapeutic effect of the poor water soluble drugs by this route led to development of novel drug delivery systems which will fulfill therapeutic needs with minimum dose. Although many formulation approaches like solid dispersions, complexation, pH modifications and lipid based delivery systems finding increased appliance with the apparent increase in absorption of drug. Among lipid based formulations, self-micro emulsifying formulations (droplet size < 100 nm) are evident to improve the oral bioavailability of hydrophobic drugs primarily due to their efficiency in facilitating solubilization and in presenting the hydrophobic drug in solubilized form whereby dissolution process can be circumvented. Various components that are used to formulate these dosage forms like surfactants and lipids contribute to the overall improvement in oral bioavailability via promoting the lymphatic transport; thereby hepatic first pass metabolism can be surmounted. The present article gives exhaustive information on the formulation design and characterization of SMEDDS by which the bioavailability can be improved. In this review article, the various aspects of pharmaceutical SMEDDS where compiled together and target audience are specifically the B. Pharm and M. Pharm students so that their knowledge towards the subject concern can be enhanced and also at the same time can be motivated towards the publication.
