Mechanism of action Orlistat, or tetrahydrolipstatin, is an orally active lipase inhibitor which reduces dietary fat absorp-tion and is marketed under the brand name Xeni-cal FORMULATION AND IDENTIFICATION AND CHARACTERIZATION OF IMPURITIES 2.1 OBJECTIVE: To develop simultaneous determination method of orlistat and sibutramine hydrochloride related substances in capsules Formulation, Identification of impurities and Characterization of sibutramine hydrochloride impurities. 2.2 INTRODUCTION: Orlistat [135] is known as tetrahydrolipstatin, a drug …

Orlistat is the saturated derivative of lipstatin, a potent natural inhibitor of pancreatic lipases isolated from the bacterium Streptomyces toxytricini. However, due to its relative simplicity and stability, orlistat was chosen over lipstatin for development as an anti-obesity drug. The mechanism responsible for this effect may be related to orlistat’s inhibition of dietary cholesterol absorption . Adverse effects The adverse event profile for orlistat treatment in this trial was very similar to that previously reported for orlistat in obese nondiabetic subjects and diabetic patients treated with oral hypoglycemic agents ( 15 , 18 ).

Mechanism of action Orlistat, or tetrahydrolipstatin, is an orally active lipase inhibitor which reduces dietary fat absorp-tion and is marketed under the brand name Xeni-cal Orlistat is an inhibitor of the gastrointestinal lipase that reduces the absorption of dietary fat by about 30%. 16 Previous studies have confirmed the efficacy of orlistat in weight reduction with improvement in cardiovascular risk factors among obese white subjects. 17-24 In contrast, there is a paucity of data on the efficacy of these drugs in Asian populations, despite the high prevalence

Orlistat is a non-systemic treatment for obesity. The drug inhibits lipase in the gastrointestinal track mainly in the lumen of the stomach and small intestine by binding reversibly with the active site of gastric and pancreatic lipases, preventing the absorption of ∼30–35% of dietary fat.

Orlistat mechanism of action. Orlistat is a reversible inhibitor of lipases. It exerts its therapeutic activity in the lumen of the stomach and small intestine by forming a covalent bond with the active serine residue site of gastric and pancreatic lipases. Orlistat mechanism of action provides unique benefits. Advantages and benefits: Effective - significant and consistent weight loss. Orlistat promotes gradual, noticeable weight loss. It is an effective therapy that not only helps people lose weight, but also helps them maintain achieved weight loss 4. Orlistat reduces body weight by an average of 5-10%. The greatest rate of weight loss occurs

Orlistat is an inhibitor of gastric and pancreatic lipase with proven efficacy in the augmentation and maintenance of weight loss. Although its use has been limited by troublesome but benign gastrointestinal side effects, it has more recently been associated with acute kidney injury (AKI). Mechanism of action: Reversibly inhibits gastric and pancreatic lipases, decreasing the absorption of dietary fat (triglycerides) by about 30%. Pharmacokinetics: About 2% of orlistat is absorbed and this is mostly metabolized within the gastrointestinal wall. Most of the drug is excreted unchanged in the feces. Evidence of effectiveness:Four double-blind RCTs are available to assess

Small reductions in circulating concentrations of the fat soluble vitamins (A, D, E, K) and β carotene (mostly within the reference ranges) are also seen. These are not thought As a result of lorcaserin’s mechanism of action as a serotonergic agonist, potential interactions may occur with medications that affect serotonergic pathways. The risk of serotonin syndrome and neuroleptic malignant syndrome (NMS)–like reactions can occur if lorcaserin is used in combination with other serotonergic agents, although these effects have not been evaluated.
