Each comes in capsule form and is available in various pack sizes, typically sold in packs of 21, 42, 84, or 90 capsules. **ATC Code:** The Anatomical Therapeutic Chemical (ATC) classification code for Orlistat is **A08AB01**, categorized as an Antiobesity preparation.

Additionally, various generic brands also provide Orlistat options. **Registration Status:** Orlistat has received approval from **Health Canada** for use both as a prescription (Rx) and over-the-counter (OTC) medication. The Alli version is available without prescription, whereas Xenical requires a doctor's authorization. **OTC/Rx Classification:** - **Alli (60 mg):** Available over-the-counter for weight management. - **Xenical (120 mg):** Prescription only, suitable for individuals needing more intensive treatment for obesity.The Pharmacology of Orlistat: How It Works
Understanding the pharmacological action of Orlistat helps in recognizing its role in weight management. **Mechanism of Action:** Orlistat operates by inhibiting pancreatic lipase, an enzyme crucial for breaking down dietary fats. In simpler terms, it stops your body from absorbing some of the fat you eat. This results in a decrease in overall fat intake, contributing to weight loss. **Onset, Metabolism, and Elimination:** - **Onset:** The effects of Orlistat can start to manifest after the first dose, but the timing may vary among individuals. - **Metabolism:** It is primarily metabolized locally in the intestine, with minimal absorption into the bloodstream, which means most of the action happens in the gut. - **Elimination:** Orlistat is excreted unchanged in the stool, making it an effective option for weight loss without significant systemic side effects. **Interactions:** - **Drug Interactions:** It is known to reduce the effectiveness of **ciclosporin**, a medication used in transplant patients. - **Food Interactions:** For optimal results, low-fat meals are encouraged while using Orlistat, as high-fat meals can diminish its effectiveness. - **Alcohol:** No specific interactions have been noted, but it is always wise to pair Orlistat with a healthy diet for the best outcomes.Safety & Warnings
