ABSTRACT
There were many reasons for writing this review article. Some relate to a continuous search for better and more efficient delivery vehicles. Others are of a more personal concern, derived from the need to design improved formulations for hundreds of new natural active molecules that have not yet been explored as drugs. Yet other reasons derive from the development of new emerging categories of food supplements that will soon become nutraceuticals and will need formulations and delivery vehicles. Liquid formulations based on nanoparticles or nanodroplets are, to the best of our understanding, the key to improved bioavailability of drugs. They provide better active molecules for systemic environmental protection of active compounds and are excellent vehicles for improved pharmacokinetics.
