Abstract: As per the present global scenario, Parkinson’s disease (PD) is considered to be the second most common
neurodegenerative disorder which is a keen area of interest among researchers. The conventional therapies
generally employed against PD are associated with serious drawbacks including limited transport across selectively
permeable BBB, hepatic metabolism, intestinal barrier, etc. This urges the need to develop novel therapeutic
alternatives. The oral route being the most preferred route of administration needs to be explored for new and
more intelligent drug delivery systems. Nanotechnology has been proposed to play a promising role in reversing
the progression of the disease via the oral route. Nanocarriers, namely nanoparticles, lipid nanoparticles, nanoemulsions,
nanocrystals, nanomicellar formulations, self-nanoemulsifying drug delivery systems and alginate
nanocomposites have been investigated upon to modulate the fate of drugs inside the human body when administered
orally. The development of various nanotherapeutics for the treatment of PD has been reviewed, depicting
an enhanced bioavailability to provide a desired therapeutic outcome. The new advances in the therapy have been
explored and highlighted through the body of this review. However, a therapeutically effective concentration at
the target site remains a challenge, therefore extensive exploration in the field of nanotherapeutics may facilitate
superior drug delivery to CNS via oral route thereby improving the state of disease progression.
