Which of the following best defines compounding in pharmaceutical practice?

• A. Manufacturing a drug for distribution to multiple pharmacies
• B. Preparation, mixing, assembly, packaging, and labeling of one or more drugs
• C. Quality control testing of finished products
• D. Distribution of medicines to patients

Answer: (B)

Compounding in pharmaceutical practice means preparing, mixing, assembling, packaging, and labeling one or more drugs to meet a specific patient’s prescription. This definition emphasizes the hands-on creation of a customized medication tailored to an individual’s needs, often when commercially available products don’t fit exactly. It involves careful weighing and combining ingredients, possibly altering the dosage form, and then ensuring the final product is packaged and labeled correctly with dosing instructions and safety information. This is distinct from manufacturing, which is large-scale production for broad distribution; quality control testing, which focuses on verifying product standards; and distribution, which is about delivering meds to patients.
