Used primarily in the treatment of narcolepsy, this compound acts as a selective histamine H3 receptor antagonist/inverse agonist. It promotes wakefulness by increasing the synthesis and release of histamine in the brain, making it effective for managing excessive daytime sleepiness in adult patients. It is also explored for off-label use in conditions involving central nervous system fatigue, such as Parkinson’s disease and obstructive sleep apnea. Due to its mechanism of action, it has a lower potential for abuse compared to traditional stimulants, offering a favorable safety profile in long-term therapy.
