Tesofensine 500mcg – 60 κάψουλες

Tesofensine 500 mcg — 60 ερευνητικές κάψουλες από του στόματος (προπαραγγελία). Tesofensine is a triple monoamine reuptake inhibitor (serotonin / noradrenaline / dopamine) originally developed for Parkinson’s και Alzheimer’s disease, where it failed efficacy endpoints — but unexpectedly produced the largest weight-loss signal ever recorded σε Phase II obesity trial. In a 24-week placebo-controlled study, 1.0 mg daily produced 12.8 kg of weight loss versus 2.2 kg on placebo: roughly twice the magnitude observed with sibutramine, και approaching the range now seen with tirzepatide και retatrutide despite a fundamentally different mechanism. The molecule has since advanced through Phase III in hypothalamic obesity. The 500 mcg per-capsule potency corresponds to the lower clinical-pharmacology dose tier.

Επισκόπηση έρευνας

Tesofensine is a tropane derivative that inhibits the dopamine, serotonσεnd noradrenaline transporters with relatively balanced affinity — distinguishing it from the predominantly serotonergic profiles of older anti-obesity SNRIs [1]. The compound was originally developed by NeuroSearch as a treatment for Parkinson’s και Alzheimer’s disease; it failed primary efficacy endpoints in those indications but unexpectedly produced sustained weight loss in nearly every cohort tested. The pivotal Phase II TIPO-1 trial reported placebo-subtracted weight loss of 6.7 % at 0.5 mg, 11.3 % at 1.0 mg και 12.8 kg at 1.0 mg over 24 weeks, with appetite reduction και reductions in hunger ratings as the proximate mechanism — the magnitude approaches modern incretin therapies despite operating through an entirely different pathway [1,2]. The molecule has subsequently been combined with metoprolol (Tesomet) to mitigate cardiovascular signal, και has advanced through Phase III in hypothalamic obesity και Prader–Willi syndrome [2,3]. In experimental research, tesofensine is widely used as a clean tool to dissect appetite-suppressing versus reward-modulating effects of triple-monoamine pharmacology.
