Compounding is defined as:

• A. The use of a computerized filling machine
• B. The pouring of medication from a manufacturer's stock bottle into a pharmacy vial
• C. The manufacturing of medications
• D. The practice of preparing customized medications for patients

Answer: (D)

Compounding is the practice of preparing customized medications for patients. It involves creating or modifying a drug product to meet an individual prescription—adjusting the dose, altering the dosage form (such as turning a pill into a liquid or ointment), combining ingredients, or removing potential allergens—so the medication fits a specific patient’s needs. This is distinct from mass production, where medications are manufactured in standard strengths and forms for broad distribution. The other scenarios describe processes not about tailoring therapy: using automated filling machinery is about dispensing and workflow efficiency, not creating a personalized formulation; pouring from a stock bottle into a vial is repackaging, not altering the product to fit a prescription; and industrial manufacturing refers to producing medications at scale for wide use rather than for a single patient.
