Xenical 120 mg by Roche is a pharmaceutical-grade oral lipase inhibitor containing orlistat as its active ingredient, indicated for the clinical management of overweight and obesity in adult patients. Available in packs of 42 capsules, orlistat is one of the most extensively researched gastrointestinal lipase inhibitors in obesity pharmacotherapy literature, with an established global clinical profile spanning decades of documented use.
✔ Key Research Insights
- Studied for its role in inhibiting pancreatic and gastric lipase activity in the gastrointestinal tract, with documented reduction in dietary fat absorption in research subjects
- Investigated for its effects on weight reduction outcomes when administered alongside reduced-calorie dietary protocols in clinical trials
- Researched for its mechanism of action as a non-systemic compound, acting locally within the digestive tract without appetite suppression or central nervous system involvement in documented observations
- Examined for its influence on obesity-related metabolic parameters in subject populations enrolled in comprehensive weight management research protocols
- Documented across extensive international clinical literature as a first-line pharmacological adjunct to dietary and lifestyle modification in overweight and obese patient populations

⚙ How It Works
Orlistat functions as a reversible inhibitor of pancreatic and gastric lipases — enzymes responsible for the hydrolysis of dietary triglycerides within the gastrointestinal lumen. Following oral administration in research subjects, orlistat binds covalently to the active site of lipase enzymes in the stomach and small intestine, preventing the enzymatic breakdown of ingested dietary fats into absorbable free fatty acids and monoglycerides. Unhydrolyzed triglycerides, unable to be absorbed through the intestinal wall, pass through the gastrointestinal tract and are excreted via bowel movements. Clinical trials have documented a reduction of approximately 30% in dietary fat absorption in subjects receiving orlistat at the 120 mg dose alongside standardized dietary protocols. Orlistat is not absorbed systemically in clinically significant amounts, and its pharmacological activity is confined to the gastrointestinal tract, distinguishing it mechanistically from centrally acting weight management compounds.

Xenical 120 mg / Orlistat
The typical recommended dosage of Xenical (Orlistat) for adults is 120 mg to be taken orally three times a day with each main meal that contains fat or within an hour after the meal. It's important to adhere to the following guidelines while using Xenical:
- Dosage Frequency: Take Xenical three times a day, typically during or up to one hour after each main meal.
- Administration: Swallow the Xenical capsule whole with water. Avoid chewing the capsule or breaking it open.
- Meal Composition: Xenical is most effective when taken with meals containing fats. However, if a meal is missed or does not contain any fat, the Xenical dose can be skipped.
- Balanced Diet: Follow a well-balanced, reduced-calorie diet that is lower in fat while using Xenical. Aim to distribute daily intake of fats, carbohydrates, and proteins evenly over three main meals.
- Vitamin Supplementation: Xenical can interfere with the absorption of fat-soluble vitamins (A, D, E, K), so it's advisable to take a multivitamin supplement at bedtime or at least two hours before or after Xenical administration.
