Orlistat at https://www.cmoapi.com/product/orlistat/ is a drug used in obesity control. This activity evaluates orlistat indications, measures and contraindications as a helpful ingredient for obesity therapy. This exercise will underline the action mechanism, adverse event profile and other important elements relevant to interprofessional team members for the treatment of Obesity Patients (e.g. off-label usage, dosage, pharmacodynamics, pharmacokinetics, monitoring, relevant interactions).


  • Identify orlistat’s method of action.
  • Describe orlistat’s negative consequences.
  • Describe orlistat’s adequate monitoring and toxicity.
  • Examine team interprofessional ways to optimize patient education for undesirable effects and correct orlistat delivery for optimal effectiveness.


The U.S. Food and Drug Administration (FDA) is an authorized anti-obesity drug called orlistat (tetrahydrolipstatin). It is an endogenous lip statin saturated derivative derived from streptomyces toxytricin. The orlistat signals authorized by the FDA include: When taken in combination with the diet and exercise, orlistat has the most benefit. Within 2 weeks after orlistat beginning, weight begins to fall. Statistically, when the usage of orlistat exceeds 2 months substantial weight reduction happens.

After six months of usage with orlistat, the average weight loss in placebo is about 5.6 kg compared to 2.4 kg. Orlistat also produces a major reduction in BMI, waist, total cholesterol and LDL. The XENDOS study has revealed that orlistat has a statistically significant influence on diabetes reduction in patients with disability in glucose tolerance.

Action Component

Orlistat works by suppressing gastric and pancreatic lipases reversibly. These lipases play a major role in food fat digestion. The triglycerides are broken down into absorbible free fatty acids and monoglycerides. 

Orlistat binds and inactivates the serine residue of active lipase sites. Free fatty acids are not used by the inactivation of lipases to avoid triglyceride breakdown. Orlistat’s principal effect is the suppression of local lipase in the intestines. For orlistat action systemic absorption is not required. It reduces the absorption of dietary fat by around 30% at its recommended dosage.


The orlistat dosage is advised for 120 mg orally three times a day. During or after 1 hour after the fat meal, administration should be carried out. There has been no further advantage at doses of more than 120 mg. It is recommended that the patient adhere to a balanced nutrient diet with a low calorie content of fewer than 30% calories.

If the patient skips food, the dose of orlistat may be omitted. If the orlistat dosage was missed and more than 2 hours after the fat meal, the pill may be omitted since most of the fat absorption has happened and the medicine would not act well at that time. As orlistat lowers fat-soluble vitamin absorption, people should also take multivitamin supplements once day, but should be given more than 2 hours after orlistat. Furthermore, before starting orlistate medication, health experts must avoid organic obesity reasons such as hypothyroidism and Cushing Syndrome.Fat-soluble vitamins and other fat-soluble foods are inhibited by Orlistat. Patients should utilise vitamin A, D, E, K, and beta-carotene multivitamin tablets once a day. You can find check this details go know more.
