Compounded semaglutide refers to a medication prepared by a compounding pharmacy, custom-made for an individual patient. This article explores the nature of semaglutide, the general practice of pharmaceutical compounding, and the specific distinctions and considerations surrounding compounded semaglutide.
Understanding Semaglutide
Semaglutide is a medication classified as a glucagon-like peptide-1 (GLP-1) receptor agonist. It mimics the action of a natural hormone, GLP-1, which is released in the gut after eating.
The FDA has approved semaglutide for various uses under specific brand names. Ozempic® and Rybelsus® are approved for managing type 2 diabetes, helping to control blood sugar and reduce cardiovascular risks in some patients. Wegovy® is approved for chronic weight management in adults and adolescents with obesity or overweight, in conjunction with diet and exercise. Semaglutide works by slowing gastric emptying, increasing insulin release, and reducing appetite.
The Practice of Pharmaceutical Compounding
Pharmaceutical compounding is the traditional process of preparing custom medications to meet the unique needs of an individual patient, based on a prescription from a licensed healthcare provider.
Reasons for compounding include customizing dosages not commercially available or creating alternative forms, such as liquids for patients unable to swallow pills. It can also involve removing inactive ingredients that a patient may be allergic to.
Compounded Semaglutide: Distinctions and Oversight
Formulation Differences
Compounded semaglutide differs significantly from FDA-approved semaglutide products, particularly in its formulation and regulatory status. While FDA-approved semaglutide products contain the active ingredient in its base form, compounded versions may use different salt forms, such as semaglutide sodium or semaglutide acetate. These salt forms are chemically distinct and have not been evaluated for safety and efficacy in humans. Their absorption, effectiveness, and safety may vary significantly.
Regulatory Status and Quality Control
A primary distinction is that compounded semaglutide products are not FDA-approved. This means they do not undergo the same rigorous review for safety, effectiveness, and quality that FDA-approved drugs do. Although compounding is legal under specific conditions, such as during a drug shortage or for a specific patient need, the FDA has issued warnings concerning compounded semaglutide, especially regarding the use of unapproved salt forms. The FDA recently removed semaglutide from its drug shortage list, indicating that manufacturers can now meet demand, which impacts the permissibility of compounding “copies” of approved products.
Quality control and oversight also differ between compounding pharmacies and large pharmaceutical manufacturers. Compounding pharmacies, particularly traditional ones (503A facilities), are primarily regulated by state boards of pharmacy, and the degree of oversight can vary by state. In contrast, outsourcing facilities (503B facilities) are registered with the FDA and are subject to more stringent regulations, including current good manufacturing practices (cGMP). However, compounded products, regardless of the facility type, do not undergo the same extensive clinical trials as FDA-approved medications. Reports have indicated that some compounded semaglutide products may contain impurities or incorrect dosages.
Patient Considerations for Compounded Semaglutide
Consulting Your Provider
Individuals considering or using compounded semaglutide should engage in open discussions with their healthcare provider. It is important to review all available treatment options, including FDA-approved medications, and to understand the potential benefits and risks associated with compounded versions. Medical decisions should always align with individual health needs and be based on comprehensive professional advice.
Sourcing and Risks
Patients should seek compounded medications only from licensed and reputable compounding pharmacies that adhere to established quality standards and operate under federal and state regulations. Obtaining medications from unregulated or unlicensed sources carries significant risks, including the potential for contaminated or improperly formulated products. The lack of FDA approval for compounded semaglutide means there may be variability in the product’s potency, purity, and overall effect, which can lead to unpredictable outcomes. Some analyses have found impurities in compounded semaglutide products, with levels reportedly as high as 33%.
Any adverse effects experienced while using compounded semaglutide should be promptly reported to a healthcare provider. Patients are also encouraged to report serious adverse events to the FDA’s MedWatch program, which collects information on suspected problems with medical products. While factors like lower cost or availability during shortages may lead some individuals to consider compounded versions, these should be carefully weighed against potential safety and efficacy concerns. The FDA has stated that the shortage of FDA-approved semaglutide products is resolved, which influences the regulatory landscape for compounded versions.
