Xenical 120mg is a prescription medication containing orlistat 120mg per capsule, primarily used for weight management in adults who are obese (BMI ≥30 kg/m²) or overweight (BMI ≥27 kg/m²) with related health risks like hypertension, diabetes, or high cholesterol. It’s not a “magic pill” but works alongside a reduced-calorie diet and exercise.

Come Funziona

• Meccanismo: Orlistat is a lipase inhibitor. It binds to enzymes in the gut (gastric and pancreatic lipases), preventing the breakdown and absorption of about 25-30% of dietary fats. Unabsorbed fats are excreted in stool.
• Prova: Clinical trials (e.g., 4-year XENDOS study, n=3304) showed ~10% average weight loss over 1 year vs. placebo, with sustained benefits when combined with lifestyle changes. FDA-approved since 1999; also EMA-approved.

Importante: This is general info from sources like FDA label, EMA SPC, and studies (e.g., PubMed). Non si tratta di un consiglio medico.—consult a doctor for personalized use, as it requires BMI assessment and monitoring. Side effects can be socially disruptive; adherence is key (~50% dropout rate in trials). If you have specific questions (e.g., interactions), provide more details!
