**7. Conclusion**

In recent decades, number of innovations have been developed in lipid-based drug delivery for oral route. Moreover, the advancements in technology transfer have also been seen favoring the production of these novel systems. The in vivo performance evaluation, in vitro drug release studies have also been improved allowing us to track the amount of drug that is able to cross the gastrointestinal tract and/or lymphatic absorption. This delivery system has proved as more useful for poorly water-soluble drugs especially for potent lipophilic drugs because of their biocompatibility and non-toxicity, solubility enhancing properties. Overall, lipid-based drug delivery is one of the safest options for the oral delivery of lipophilic drugs.
