Most do. According to the American Pharmacists Association and the National Community Pharmacists Association, compounding is done to some degree in 90% of all hospital pharmacies and 80% of all independent pharmacies. All pharmacists are permitted by law to compound as part of the practice of pharmacy: however, compounding pharmacists have learned skills above and beyond those they were taught in school. Compounding also requires a substantial commitment on the part of the pharmacy owner of time (each prescription is individually made in the pharmacy, not just transferred from one bottle to another) and money (for additional training and purchase of the specialized equipment that is required to make a quality product). Accreditation for compounding pharmacies will be available in the future.
