Compounding is the art and science of creating personalized medicines, a practice that dates back to the origins of pharmaceuticals.
Within the last two decades, compounding has experienced a resurgence as modern technology and innovative techniques have allowed more pharmacists to customize medications.

Compounding pharmacists work directly with doctors and practitioners to provide customized treatment options that circumvent uncomfortable issues. Medications may be given transdermally (through the skin), in lipsticks or lip balms, and in oral and topical sprays, sublinguals.
