Abstract
It is appropriate that the improved oral delivery of problematic drugs via prodrugs is treated early in this book. This chapter provides the rationale for the use of prodrugs along with selective examples of prodrugs used to effect improved oral delivery of poorly permeable drugs. Oral drug delivery is the preferred route of dosing in the USA and much of the rest of the world. Marketing forces therefore dictate that every attempt be made to provide an oral form of a drug that shows promise. Major exceptions are drugs used to treat emergencies where fast-acting injectables or inhalables are desired or drugs used to treat cancer where traditionally injectables have been well accepted and many older anticancer drugs are irritating to the gastrointestinal tract (GIT).
