Rivastigmine, a cholinesterase inhibitor primarily used in the treatment of Alzheimer's disease, has also been investigated for its potential neuroprotective effects in Parkinson's disease, a progressive neurodegenerative disorder characterized by motor symptoms such as tremors, rigidity, and bradykinesia. This concise review focuses on exploring the potential of it as a neuroprotective agent in Parkinson's disease. Parkinson's disease involves the degeneration of dopamine-producing neurons in the brain. Its mechanism of action as a cholinesterase inhibitor is thought to enhance cholinergic activity and modulate the balance between acetylcholine and dopamine, potentially providing neuroprotective benefits. Preclinical studies have shown promising results, suggesting that it may have neuroprotective properties in Parkinson's disease models.
It has been observed to promote neuronal survival, reduce oxidative stress, and attenuate neuroinflammation, contributing to the preservation of dopaminergic neurons. Clinical trials investigating the use of it in Parkinson's disease have reported mixed results. While some studies have shown modest improvements in motor symptoms and cognition, others have not demonstrated significant benefits. Further research is needed to determine the optimal dosing regimen, patient selection criteria, and long-term effects of it in Parkinson's disease. It is worth noting that rivastigmine is not currently approved by regulatory agencies for the treatment of Parkinson's disease. However, its potential neuroprotective effects warrant continued exploration and evaluation in well-designed clinical trials.
