Sibutramine came in the market firstly as an antidepressant but because of its reduced efficacy for depression it was rather used for weight loss. It is a beta phenethylamine with a cyclobutyl group on its side chain. The mechanism of action of Sibutramine primarily revolves around the increase of satiety in an individual. It acts by inhibiting the release of three major neurotransmitters serotonin, norepinephrine and dopamine. It also acts by increasing the metabolism of the body which further increases the energy expenditures and thus helps a person to lose weight. While the person reduces his weight the metabolism of the body is still not reduced because of the activity of Sibutramine. Sibutramine has a role to play in nutrient drug interaction as it increases the metabolism of the body. It is necessary that the drug is prescribed with a regular balanced diet so that the satiety of the person is satisfied. Its side effects include increased blood pressure, dry mouth, insomnia and headache (Foster & Nonas 2004; Poston & Foreyt 2004).
Orlistat is also a drug prescribed for patients who are suffering from obesity. Orlistat is a derivative of lipstatin which acts differently than Sibutramine. Their primary mechanism of action is to lower the amount of calories absorbed from the gut. Orlistat inhibits the action of pancreatic lipases so that the fats cannot be digested and absorbed.
This helps in reducing the caloric intake of an obese individual. It works in a dose dependent manner which determines as to how much fat would be absorbed from the intestine. The effect of orlistat is such that after having a meal with high content of fat the patient usually has steatorheal diarrhea. But this diarrhea cannot prove to be fatal for the patient. The patients on orlistat usually have a deficiency of fat soluble vitamins as they cannot be absorbed from ...Download file to see next pages Read More

Autoimmune Diseases and the Importance of Their Treatment in the Modern Society

Obesity: Full-Blown Epidemic or Overblown Epidemic

First noted in the adults, it has now spread to adolescents and children. It appears odd and seems extremely worrisome to note sudden emergence and rapid increase of a new obesity-associated medical condition, type 2 diabetes in children (Environmental Nutrition, 2004).

This implies a contested scientific topic and controversial social fact. It would thus be worthwhile to critically appraise the idea of an obesity epidemic that allegedly afflicts a large proportion of the countries of the world and indeed reportedly threatens a global health catastrophe.

The ways in which the treatment of young offenders is differentiated from that of adult offenders are also presented using appropriate literature; particular reference is made to the role of Young Offender Institutions (YOI).
