Lazabemide is primarily used in research settings to study its effects on monoamine oxidase-B (MAO-B) inhibition. It has been investigated for its potential therapeutic applications in neurodegenerative diseases, particularly Parkinson's disease, due to its ability to modulate dopamine levels in the brain. Additionally, lazabemide has been explored for its neuroprotective properties, which could help in slowing the progression of conditions like Alzheimer's disease. Its role in enhancing cognitive function and memory has also been a subject of interest in preclinical studies.
