Tesofensine

Tesofensine was originally developed for neurological conditions such as Alzheimer’s and Parkinson’s disease, but later showed significant appetite-suppressing and weight-loss effects during clinical trials.

It works by increasing levels of key neurotransmitters in the brain:

• Dopamine → affects reward and motivation (reduces food cravings)
• Serotonin → improves satiety and mood regulation
• Norepinephrine → increases metabolic activity and alertness

Clinical studies showed notable weight reduction compared to placebo, but development for obesity treatment has been limited due to:

• Potential side effects (increased heart rate, insomnia, anxiety)
• Lack of final regulatory approval in major markets

It remains a research-use compound only and is not legally approved as a prescription weight-loss medication in most countries.
