The fourth volume in the six-volume Handbook of Pharmaceutical Manufacturing Formulations, this book covers semi-solid drugs. It includes ointments, lotions, gels, and suppositories, from publicly available but widely dispersed information from FDA New Drug Applications (NDA), patent applications, and the BASF book of generic formulations. Each entry begins with a fully validated scaleable manufacturing formula that includes compendial specification requirement for each ingredient, in-process controls for manufacturing and release of product, a summary of manufacturing process, and details of packaging.
