The board shall establish written procedures for the compounding of drug products to assure that the finished products have the identity, strength, quality, and purity they purport to have or are represented to possess. The procedures shall include, but not be limited to, a listing of the components, their amounts in weight or volume, the lot number of the components, if available, the order of component mixing, a description of the compounding process, and a designated name for the finished product. The procedures shall be followed in the execution of the compounding procedure. Components shall be accurately weighed, measured, or subdivided, as appropriate. The operations shall be checked and rechecked by the compounding pharmacist at each stage of the process to ensure that each weight and measure is correct as stated in the written compounding procedures. Pharmacists shall determine that all finished products have an acceptable degree of weight variation among capsules, and shall assure a reasonable uniformity and integrity of all compounded products.
