Recent trends in nanoparticulate delivery system for amygdalin as potential therapeutic herbal bioactive agent for cancer treatment.

Cancer is the deadliest and most serious health problem. The mortality rate of cancer patients has increased significantly worldwide in recent years. There are several treatments available, but these treatments have many limitations, such as non-specific targeting, toxicity, bioavailability, solubility and permeability problems, serious side effects, and a higher dose. Many people prefer phytomedicine because it has fewer side effects. However, amygdalin is a naturally occurring phytoconstituent. It has many harmful effects due to the cyanide group present in the chemical structure. Many scientists and researchers have given their thoughts associated with amygdalin and its toxicities. However, there is a need for a more advanced, effective, and newer delivery system for amygdalin to reduce its toxic effect. Nanotechnology has become a more refined and emerging medical approach, offering innovative ways to treat cancer. This review focuses on the use of amygdaline as herbal medicine encapsulating into several nanoparticulate delivery systems such as silver nanoparticles, graphene oxide nanoparticles, gold nanoparticles, nanofibers, nanocomposites, niosomes, and magnetic nanoparticles in the treatment of cancer. In addition, this article provides information on amygdalin structure and physical properties, pharmacokinetics, toxicity, and challenges with amygdalin.
