Overview
Brief Summary
Obesity is a chronic condition with fat-rich diets playing a major role in its etiology. Pharmacological therapy has been proposed for weight loss and maintenance. This study aims to study the intestinal lipase blockade by partial inhibition of fat absorption after treatment with two commercials formulations of Orlistat.
Detailed Description
The overweight and obesity epidemic affects approximately 1.6 millions of people worldwide. Obesity is a chronic condition, associated with premature death, co-morbidities, risk factors for main cardiac disease, stigmatization and significant economic costs. The causes of obesity are complex and include the interplay of environmental, social, economic and genetic factors. Besides fat-rich diets also play a significant role in the etiology of obesity. Correct diet orientation associated with physical exercise usually did not lead to expected result in weight loss and maintenance. Pharmacological therapy has been proposed as an adjunct to achieve the ideal weight. Orlistat acts in reduction of lipids absorption by inhibition of gastric and pancreatic lipases in gastrointestinal tract leading to sustained weight loss. This is a double blind study, randomized, of 2 weeks. The aim of this study was evaluate the intestinal lipase blockade by decrease of fat absorption of fecal fat after treatment with two commercials formulations of Orlistat in obese patients.

Outcomes
Primary Outcomes
Study of equivalence between two commercial capsules of Orlistat on fat absorption inhibition
Time Frame: baseline
This study aim to investigate differences in fat absorption inhibition after 7 days treatment with Lipiblock and Xenical (two commercial capsules of Orlistat). Therefore, total fecal fat and fecal fat percentage wil be analysed, comparing these data before and after treatment with Lipiblock and Xeical.
Secondary Outcomes
- Study of equivalence between two commercial capsules of Orlistat on fat absorption inhibition(after 7 days Orlistat treatment)
