Abstract:
Background: One of the most prevalent neurodegenerative diseases with increasing age
is Parkinson’s disease (PD). Its pathogenesis is unclear and mainly confined to glutamate toxicity
and oxidative stress. The dyskinesia and motor fluctuations and neuroprotective potential are the
major concerns which are still unmet in PD therapy.
Objective: This article is a capsulization of the role of MAO-B in the treatment of PD,
pharmacological properties, safety and efficiency, clinical evidence through random trials, future
therapies and challenges.
Conclusion: MAO-B inhibitors are well tolerated for the treatment of PD because of their
pharmacokinetic properties and neuroprotective action. Rasagiline and selegiline were
recommended molecules for early PD and proven safe and provide a modest to significant rise in
motor function, delay the use of levodopa and used in early PD. Moreover, safinamide is
antiglutamatergic in action. When added to Levodopa, these molecules significantly reduce the offtime
with a considerable improvement of non-motor symptoms. This review also discusses the new
approaches in therapy like the use of biomarkers, neurorestorative growth factors, gene therapy,
neuroimaging, neural transplantation, and nanotechnology. Clinical evidence illustrated that MAOB
inhibitors are recommended as monotherapy and added on therapy to levodopa. A large study
and further evidence are required in the field of future therapies to unwind the complexity of the
disease.
