Lower bioavailability is one of the main culprit for new drug entity when formulation is to be decided. Self-emulsifying drug delivery systems (SEDDS) are the type of formulations where drug itself is given in presolubilized form which improves the bioavailability by virtue of improvement in dissolution. As it is lipid based system it also improves the permeability. Certain disadvantages associated with conventional SEDDSs are now overcome by some of the recent advancement are described in this manuscript with recent patents in such fields.
