Which of the following is prohibited under compounding laws?

• A. Compounding from FDA-approved ingredients
• B. Using ingredients withdrawn from the market
• C. Preparing small batches of medications
• D. Compounding specific doses for patients

Answer: (B)

Compounding laws are designed to ensure the safety and efficacy of compounded medications. One of the key prohibitions within these laws is the use of ingredients that have been withdrawn from the market, which is what makes this choice correct. The rationale behind this regulation is rooted in patient safety; ingredients withdrawn from the market may have been associated with safety concerns, lack of efficacy, or other serious issues that could jeopardize the health of patients.

When compounding pharmacists use ingredients that are still on the FDA's approved list, they ensure that the products they prepare meet established safety standards. Additionally, preparing small batches and compounding specific doses for patients are integral parts of a pharmacist's role, allowing them to customize medications based on individual patient needs. Therefore, they do not violate compounding laws. The focus of the prohibition on using withdrawn ingredients maintains the overall goal of protecting public health and ensuring safe pharmaceutical practices.
