Used in clinical research for the treatment of cognitive impairments associated with Alzheimer's disease. Acts as a selective histamine H3 receptor antagonist, aiming to enhance neurotransmission involved in memory and learning. Has been investigated for improving cognitive function in patients with mild to moderate Alzheimer’s due to its potential to increase histamine and other key neurotransmitter activity in the brain. Studies have also explored its use in other neurological conditions involving attention and wakefulness, such as schizophrenia-related cognitive deficits and narcolepsy.
