New perspectives on lipid and surfactant based drug delivery systems for oral delivery of poorly soluble drugs. The only problem with microemulsion is poor palatability and moreover due to their water content, microemulsions cannot be encapsulated in soft and hard gelatin Shinde et al. In current years, new chemical entities exhibit poor aqueous solubility which in turn leads to low oral bioavailability Robinson, Some patients have a single lifetime depressive episode, whereas a larger proportion have a recurrent or even chronic course.
