ANS: A Lomotil, a Schedule V drug, has an abuse potential of limited physical or psychological dependence liability compared with drugs in Schedule IV. Because abuse potential is low with a Schedule V drug, a prescription may not be required. Psychological dependency is not likely with a Schedule V drug.

The Controlled Substances Act addresses only controlled substances and their categorization. The Kefauver Harris Drug Amendment ensures drug efficacy and greater drug safety. Drug manufacturers are required to prove to the FDA the effectiveness of their products before marketing them.

Which resource(s) would be appropriate to use in determining the medication names and doses? (Select all that apply.) a. Martindale—The Complete Drug Reference b. Physicians' Desk Reference, Section 4 c. Senior citizens' center d. Patient's home pharmacy

ANS: B, D The Physicians' Desk Reference, Section 4, has full color images of commonly dispensed tablets and capsules.

ANS: D Once the Investigational New Drug Application has been approved, the drug can receive highest priority within the agency, which is called fast tracking. A smallpox outbreak would become a priority concern in the world. Orphan diseases are not researched in a priority manner. Preclinical research is not omitted. Extending any phase of the research would mean a longer time to develop a vaccine. The FDA must ensure that all phases of the preclinical and clinical research phase have been completed in a safe manner.
