Compounding Techniques for Topical and Transdermal Preparations

Pharmaceutical compounding is considered an art and science that involves preparing medications for the unique health needs of individual patients. Compounded nonsterile preparations (CNSPs) encompass many dosage forms, including transdermal and topical preparations. These dosage forms have many benefits in the pharmaceutical care of patients, including convenience, ease of application, and improved medication adherence. Pharmacists and pharmacy technicians who compound topical and transdermal medications should be well-versed in compounding standards and skilled in the techniques needed to prepare compounds that are effective, safe, and high quality. This continuing education program will review the importance of topical and transdermal preparations, discuss United States Pharmacopeia (USP) standards pertaining to these dosage forms, and review techniques related to preparing ointments, creams, pastes, and gels.
