What is Tesofensine?
Tesofensine (TE) inhibits neurotransmitter presynaptic reuptake of noradrenaline, dopamine, and serotonin. Other forms of selective serotonin reuptake inhibitors are used to treat depression and eating disorders, but they have not consistently resulted in long-term weight loss.
Molecular Formula: C17H23Cl2NO
Tesofensine was first investigated for its potential to treat Parkinson’s disease and Alzheimer’s because it blocks the reuptake of serotonin, noradrenaline, and dopamine. Unfortunately, the test volunteers started dropping too much weight, therefore it was unable to fully explore its potential for these indications. Since then, tesofensine’s appetite-suppressing properties have been investigated for their potential as a treatment for obesity. This chemical compound has been shown to be more effective than other weight-loss drugs because of the indirect stimulation it provides to the cholinergic system. The brain’s transmission of three monoaminergic neurotransmitters is boosted by teofensine (TE). Serotonin, norepinephrine, and dopamine are neurotransmitters that have been associated to weight control and mental health issues including depression and obesity. Results from a phase 2b clinical research showed that after 6 months of use, participants lost an average of 25 pounds. Recent studies have indicated that TE has a significant impact on feelings of hunger while having just a little impact on metabolic rate. In other cases, both effects may be responsible for the dramatic weight loss.
The diagram below will be useful in explaining how it can work
This was a Phase 2 randomized, double-blind, and placebo-controlled trial that involved all 203 obese patients following a calorie-restricted diet.
They either took a placebo, 0.25 mg, 0.5 mg, or 1 mg of tesofensine once a day for 24 weeks straight:
- The placebo group had a mean weight loss of 2%
- The 0.25 mg Tesofensine group had a mean weight loss of 4.5%
- The 0.5 mg Tesofensine group had a mean weight loss of 9.2%
- The 1.0 mg Tesofensine group had a mean weight loss of 10.6%
