Tesofensine (Tesofensine (Triple Monoamine Reuptake Inhibitor))

Category: Weight Management. Status: Phase 3 Clinical Trial.

A triple monoamine reuptake inhibitor that blocks norepinephrine, serotonin, and dopamine reuptake, producing significant appetite suppression and increased metabolic rate.

How it works

Blocks presynaptic reuptake of noradrenaline, dopamine, and serotonin in the hypothalamus, enhancing satiety signaling, reducing food reward, and increasing thermogenesis.
