Tesofensine is a synthetic small-molecule compound studied for its potential role as a triple reuptake inhibitor, affecting the neurotransmitters serotonin, norepinephrine, and dopamine. It is primarily investigated for its effects on appetite regulation and energy balance.

Tesofensine is believed to reduce caloric intake by modulating central nervous system pathways involved in satiety and reward, while potentially increasing energy expenditure. It is commonly researched for its possible effects on weight management, body composition, and metabolic health in preclinical and clinical studies of obesity.
