ATI Pharmacology Exam 1 Questions

Question 1 of 5

Before marketing a new drug that has been approved for use based on clinical effectiveness and safety, the manufacturer wishes to study the potential new uses for the drug. This is an example of which phase of study?

Correct Answer: D

Rationale: The correct answer is D: Phase IV. Phase IV trials are conducted after a drug has been approved for use, aiming to study additional uses, long-term effects, and optimal dosages. In this scenario, the manufacturer is exploring potential new uses for the approved drug, which aligns with the objectives of Phase IV trials. Phase I trials focus on initial safety and dosing in humans, Phase II trials evaluate effectiveness and side effects in a larger group, and Phase III trials compare the new treatment to existing treatments.
Therefore, these phases do not directly apply to studying new uses of an already approved drug.
