Orlistat is an internationally recognized new form of weight loss drug. Its commercial name is Sainike and first went on sale in New Zealand in 1998. Orlistat is a long-term and highly effective specific gastrointestinal lipase inhibitor, and it is insoluble in water, soluble in chloroform, and easily soluble in ethanol. Orlistat can be used clinically to treat obesity. Usually, a dose of 120mg is taken three times a day within one hour of a meal. Weight loss begins to occur after two weeks of usage. It can be used continuously for 6-12 months, and its effects will cease to increase after daily dosage exceeds 400mg. This drug is suitable to be used in combination with a low-calorie diet by obese and overweight individuals, and it can also be used as long-term treatment for patients who have faced weight-related risk factors. Orlistat has a long-term weight-control effect that reduces and maintains weight and prevents against rebounding. Using Orlistat can lower the occurrences of weight-related risk factors and diseases, including hypercholesterolemia, type-2 diabetes, impaired glucose tolerance, hyperinsulinemia, and hypertension, and it can reduce the fat content in organs. Orlistat also adjusts blood lipid levels: it can decrease serum triglycerides (TG) and low density lipoprotein cholesterol (LDL-C), and it can increase the ratio of high density lipoproteins to low density lipoproteins in obese patients.

Orlistat is a type of lipase inhibiting weight loss drug and is a hydrated derivative of lipostatin. Orlistat effectively and selectively inhibits stomach lipase and pancreatic lipase, while having no impact on other digestive enzymes (such as amylase, trypsin and chymotrypsin) and on phospholipase, nor does it affect the absorption of carbohydrates, protein and phospholipids. This drug is not absorbed though the gastrointestinal tract and has a reversible inhibiting effect on lipase. Orlistat deactivates enzymes by covalent binding to the serine residue on the active sites of stomach and pancreatic lipase. This prevents the fat in food from being broken down into free fatty acids and diacylglycerol, so it cannot be absorbed, lowering caloric intake and therefore controlling body weight. This drug does not need to be absorbed by the entire body to take effect. Orlistat’s pharmacological activity is dose dependent: a treatment dosage of Orlistat (120mg/d, tid, taken with meals), combined with a low-calorie diet, can reduce up to 30% of fat absorption. In a study comparing normal and obese volunteers, Orlistat was basically not absorbed by the body at all and had a very low blood concentration. After a single oral dosage (the largest being 800mg), the blood concentration of Orlistat in the following 8 hours was <5 ng/ml. Typically, a treatment dosage of Orlistat is only minimally absorbed by the body and will not accumulate in a short treatment period. In an in vitro experiment, Orlistat’s binding rate with other serum proteins exceeded 99% (bound proteins were mainly lipoproteins and albumin), and its binding rate with red blood cells was very low.
