Tesofensine- Summary
- Vialox is a synthetic pentapeptide that mimics the activity of conotoxin from cone snails, acting as an antagonist of nicotinic acetylcholine receptors at the neuromuscular junction. Similar to Syn-Ake but derived from cone snail venom biochemistry, it reduces facial muscle contraction to smooth expression wrinkles.
- Tesofensine is a triple monoamine reuptake inhibitor (TMRI) that blocks reuptake of serotonin, dopamine, and norepinephrine. Originally developed for Alzheimer's and Parkinson's disease, it was repurposed as a potent weight loss agent after clinical trials demonstrated substantial fat loss via appetite suppression and increased energy expenditure.

- Typical Dose
- 0.005-0.05% in formulation
- 0.25-0.5 mg per day
- Frequency
- Twice daily
- Once daily
- Key Benefits
- Reduces dynamic wrinkles from repetitive facial expressions
- Reversible muscle-relaxing effect without injection
- Smooths forehead, periorbital, and perioral lines
- Complementary to collagen-stimulating peptides
- Well-studied tolerability in cosmetic concentrations
- Can be combined with Syn-Ake for dual conotoxin/viper venom effect
- Potent appetite suppression via triple monoamine reuptake inhibition
- Significant weight loss (8-12% body weight in phase II trials at 0.5 mg)
- Increases basal metabolic rate and energy expenditure
- Reduces fat mass preferentially over lean mass
- Potential cognitive benefit via dopaminergic and noradrenergic enhancement
- Longer half-life than sibutramine allows once-daily dosing
- Side Effects
- Generally very well-tolerated topically
- Rare contact sensitivity or mild irritation
- No clinically significant systemic neuromuscular effects at cosmetic doses
- Elevated heart rate and blood pressure (sympathomimetic)
- Dry mouth
- Insomnia and sleep disturbances
