Tesofensine: Benefits & Research

Phase 2 trials demonstrated tesofensine as one of the most effective single-agent anti-obesity compounds tested, with 10.6% weight loss at 0.5 mg over 24 weeks. This exceeds the typical 5–8% achieved with approved anti-obesity medications at the time of the trial.

Tesofensine's triple reuptake inhibition produces comprehensive appetite suppression through complementary pathways — serotonin enhances satiety, dopamine reduces reward-driven eating, and norepinephrine increases alertness and metabolic rate. Participants reported significantly reduced hunger and food cravings.

Norepinephrine reuptake inhibition activates sympathetic nervous system thermogenesis, increasing resting energy expenditure. Studies showed tesofensine increased fat oxidation and metabolic rate, producing weight loss through both reduced intake and increased output.
