How Xenobese Capsule 120 mg works

Xenobese Capsule 120 mg is a potent and selective inhibitor of various lipase enzymes responsible for the metabolism of fat. It acts in the gastrointestinal (GI) tract via covalent binding to the serine residues located on the active site of both gastric and pancreatic lipase. When orlistat is taken with food containing fat, it partially inhibits the hydrolysis of triglycerides. This decreases absorption of monoaclglycerides and free fatty acids, contributing to weight maintenance and weight loss.

Dosage

Xenobese Capsule 120 mg dosage

The recommended dose of Xenobese Capsule 120 mg is one 60 mg or 120 mg capsule three times a day with each main meal containing fat (during or up to 1 hour after the meal). The patient should be on a nutritionally balanced, reduced-calorie diet that contains approximately 30% of calories from fat. The daily intake of fat, carbohydrate, and protein should be distributed over three main meals. If a meal is occasionally missed or contains no fat, the dose of Xenobese Capsule 120 mg can be omitted.

Because Xenobese Capsule 120 mg has been shown to reduce the absorption of some fat-soluble vitamins and beta-carotene, patients should be counseled to take a multivitamin containing fat-soluble vitamin to ensure adequate nutrition. The vitamin supplement should be taken at least 2 hours before or after the administration of Xenobese Capsule 120 mg, such as at bedtime.

Side Effects

Commonly-observed adverse events associated with the use of Xenobese Capsule 120 mg include oily spotting, flatus with discharge, fecal urgency, fatty/oily stool, oily evacuation, increased defecation, fecal incontinence.

Toxicity

The oral LD50 of orlistat is >5000 mg/kg in rats. Single orlistat doses of 800 mg and multiple doses of up to 400 mg three times a day for 15 days have been administered to healthy weight and obese subjects without clinically significant adverse findings. In addition, doses of 240 mg three times a day have been given to obese patients for 6 months without a significant adverse effects. Post-marketing reports of overdoses cases indicate no adverse events or adverse events that are similar to those reported with the recommended dose. If a significant overdose with orlistat occurs, the patient should be observed for at least 24 hours. Based on the results of clinical studies, systemic effects caused by orlistat are likely to be rapidly reversible.

Precaution

Patients should be advised to adhere to dietary guidelines. gastrointestinal events may increase when orlistat is taken with a diet high in fat (>30% of calories from fat). The daily intake of fat should be distributed over three main meals. If a meal is missed, the dose of orlistat may be omitted.

Interaction

May reduce the absorption of iodine salts and/or levothyroxine, fat-soluble vit (A, D, E, K) and beta carotene. May decrease plasma levels of ciclosporin and amiodarone. May decrease the efficacy of antiepileptic drugs (e.g. valproate, lamotrigine), antiretrovirals, antidepressants, antipsychotics (including lithium). Additive effect on glycaemic control with antidiabetics. May cause hormonal contraceptive failure. May enhance the anticoagulant effect of warfarin.

Food Interaction

• Take with food. Take with meals or up to 1 hour after a meal. Doses may be skipped for missed meals or fat-free meals.

Xenobese Capsule 120 mg multivitamins interaction

[Minor] Xenobese Capsule 120 mg decreases the absorption of fat-soluble vitamins.

Studies have shown a 30% reduction in beta-carotene absorption and a 60% reduction in tocopherol acetate absorption when coadministered with orlistat.

Vitamin supplements should be taken at least two hours before or after orlistat administration.

Xenobese Capsule 120 mg Disease Interaction

Major: malabsorptionModerate: diabetics, (fat soluble) vitamin deficiency, nephrolithiasis

Volume of Distribution

Volume of distribution cannot be obtained because the absorption of orlistat is minimal. Xenobese Capsule 120 mg is minimally distributed to erythrocytes and is primarily bound to proteins.

Elimination Route

The systemic absorption and exposure of orlistat is low, however, systemic absorption of the drug is not required for orlistat activity. After an oral dose with 360 mg of radiolabeled orlistat, plasma radioactivity achieved a peak at about 8 hours. Plasma concentrations of unchanged parent drug were close to the lower end of detection limits (15

Half Life

The half-life of orlistat of the small amount of absorbed orlistat ranges between 1-2 hours.

Elimination Route

After single oral dose of radiolabled orlistat in both normal weight and obese volunteers fecal excretion of the unabsorbed drug was found to be the major route of elimination with 11,20 Fecal elimination of orlistat is estimated between 95-97%. Complete excretion by both routes occurs within in 3 to 5 days.

Pregnancy & Breastfeeding use

Pregnancy Category X. Xenobese Capsule 120 mg is contraindicated during pregnancy, because weight loss offers no potential benefit to a pregnant woman and may result in fetal harm.

Acute Overdose
