Poorly Solubility of orally administered drug is major challenge of pharmaceutical industry as nearly 35-40% of newly launched drugs possess poor aqueous solubility which leads to their poor dissolution and low bioavailability, resulting in high intra & inter subject variability & lack of dose proportionality. Self-micro emulsifying drug delivery technique is the one of the process for improving the solvency of the hydrophobic medication. The medications which are insoluble in water can be formulated in this technique by solubilizing it in the lipid vehicle to absorb through the membrane. The lipid and surfactants are utilized to build the solvency of the drug and improve absorption. This improves the dissolution rate of the drug by expanding its solubility. Oral bioavailability of hydrophobic drugs can be improved using SEDDS, and appears most promising. Their dispersion in gastro intestinal (GI) fluid after administration forms micro or nano emulsified drug which gets easily absorbed through lymphatic pathways bypassing the hepatic first pass metabolism. SMEDDS are isotropic mixtures of oil, surfactant, co-surfactant and drug with a unique ability to form fine oil in water microemulsion upon mild agitation following dilution with aqueous phase. This article gives an overview of SMEDDS as a promising approach to effectively tackle the problem of poorly soluble drugs.
