Compounding involves the preparation, mixing, assembling, packaging, and labeling of a drug or device as the result of a licensed practitioner’s prescription drug order or initiative based on the practitioner/patient/pharmacist relationship during professional practice. Compounded drug products are tailored to meet the individual needs of patients. Pharmacies engaged in the compounding of drug products must comply with current regulations and quality standards outlined in the United States Pharmacopeia–National Formulary. Pharmacists are responsible for ensuring that compounding procedures are followed and that equipment is maintained in a clean and sanitary condition to prevent harm to patients. Pharmacies may compound drug products to dispense to patients pursuant to a prescriber’s prescription order, for over-the-counter sale, and for a prescriber’s office use. Pharmacies engaged in compounding sterile products must be registered and certified by the Alabama Board of Pharmacy as a parenteral sterile compounding pharmacy.
