Quizplus · Accepted Answer

Phase III of new drug testing involves extensive clinical trials conducted at multiple sites throughout the country with large numbers of clients. This phase concludes with a new drug application being submitted to the U.S. Food and Drug Administration (FDA). Phase I testing defines the range of dosages tolerated in healthy individuals. Phase II testing studies the effects of the drug in a limited number of persons with the disorder and defines a range of clinically effective dosages. Phase IV involves drug studies that continue after FDA approval to detect new or rare adverse reactions and potentially new indications.
