Cetilistat: A Comprehensive Guide
What is Cetilistat?
In the world of weight management and obesity treatment, cetilistat API has emerged as a promising pharmaceutical option compared to orlistat.
While it may not be as widely known as other newly emerging weight-loss peptides such as semaglutide and tirzepatide, cetilistat has garnered attention for its unique mechanism of action and potential benefits.
Cetilistat is an oral anti-obesity medication that belongs to a class of drugs known as lipase inhibitors, along with orlistat.
Lipase inhibitors work by blocking the action of enzymes in the digestive system that break down fats, thereby reducing the absorption of dietary fats.
This mechanism helps individuals manage their weight by decreasing calorie intake from fat.
Unlike other weight-loss medications, cetilistat is designed to act locally in the gastrointestinal tract, minimizing systemic absorption and potentially reducing the risk of side effects.
What is Cetilistat Used For?
Cetilistat is primarily used to manage obesity by supplementing lifestyle changes, such as diet and exercise.
It is prescribed to individuals with a body mass index (BMI) of 28 kg/m² or higher, particularly those who have weight-related health conditions like type 2 diabetes, high cholesterol, or hypertension.
By reducing fat absorption, cetilistat helps patients achieve a calorie deficit, essential for weight loss.
It is not a standalone solution but a tool to support long-term weight management combined with healthier living habits.
What are Cetilistat Side Effects?
The most common side effects of cetilistat are related to its mechanism of action in the digestive system and may include:
- Gastrointestinal issues: Oily stools, diarrhea, abdominal pain, flatulence, and fecal urgency.
- Headache: Some users may experience mild headaches.
- Fat-soluble vitamin deficiency: Since cetilistat reduces fat absorption, it may also decrease the absorption of fat-soluble vitamins (A, D, E, and K). Patients are often advised to take vitamin supplements to counteract this effect.
These side effects are temporary and diminish as the body adjusts to the medication.
However, if they persist or worsen, consult your doctor.
Cetilistat vs Orlistat
People often compare cetilistat with orlistat, another lipase inhibitor widely used for weight management.
Both medications work similarly by inhibiting fat absorption, but there are some key differences:
1. Side Effect Profile:
Research shows that cetilistat has a milder gastrointestinal side effect profile than orlistat.
This superiority in side effects may make it a more tolerable option for some patients.
2. Mechanism of Action:
While both drugs inhibit lipase enzymes, cetilistat has a slightly different chemical structure, which may contribute to its reduced systemic absorption and fewer side effects.
3. Availability:
Orlistat is more widely available and has been on the market longer, while cetilistat is still gaining FDA approvals in many countries.
Ultimately, the choice between cetilistat and orlistat depends on your needs and your doctor’s recommendations.
Is Cetilistat FDA Approved?
Currently, cetilistat is not US FDA-approved for use in the United States.
However, it has been approved in other countries, including Japan, where it is marketed under Oblean.
In Japan, cetilistat has been used as a treatment for obesity and metabolic syndrome.
The lack of FDA approval means that cetilistat is not currently available for prescription in the U.S., but ongoing research and clinical trials may influence its future regulatory status.
How Much Does Cetilistat API Cost?
The price of cetilistat API depends on your order quantity and purity requirement.
Please note that this API still lacks a GMP in China. Therefore, cetilistat can only be used for research and is unsuitable for human use.
Some of the importers are looking for Reference Standards with a purity higher than 99.9%; in that case, we don’t have it, and what we know is that RS is very expensive, sold by mg, not even grams.
If you need a 99% pure powder for research, please refer to our prices below.
For 1 kg of 99% pure powder, our price is 580 USD for your reference.
For order quantities of 100G~200G, our price is 1~2 USD per gram
If you need prices for other quantities, please get in touch with us directly.
