To overcome these limitations, efficacious formulations
of curcumin, including nanocrystal solid dispersion,
amorphous solid dispersion, and nanoemulsion, are being
developed [65]. Some adjuvants that may block metabolic
pathways of curcumin are also being used to improve the bioavailability
of curcumin. Other promising formulations such as
liposomes, micelles, nanoparticles, and phospholipid complexes,
which provide longer circulation, better permeability,
and resistance to metabolic processes are also being used [1].
