Nanotechnological Approach for Design and Delivery of Phytopharmaceuticals

Natural phytoconstituents play a vital role in the treatment of disease in humans. Problems associated with these natural compounds like solubility, absorption, stability, half-life, metabolism, and rapid excretion make it not suitable to dispense through the conventional dosage forms. Hence, researchers are in search for the development of novel drug delivery system of medicine to overcome aforementioned hindrances. Recently, research and development in nanotechnology has been combating these issues by developing nanocarriers for the efficient delivery of these phytoconstituents. In this chapter, we discuss the challenges associated with the development of novel formulations and focus on the design and development of various nanocarriers like phytosomes, liposomes, transfersomes, ethosomes, solid lipid nanoparticles, nanoemulsion, self-microemulsifying and nanoemulsifying system, and polymeric nanoparticle and microsphere and its future prospective.
