Approval of AZT for use in treating AIDS is under the jurisdiction of which agency?

The approval of AZT (zidovudine), which was one of the first antiretroviral drugs used to treat HIV/AIDS, falls under the jurisdiction of the United States Food and Drug Administration (FDA). The FDA is responsible for ensuring the safety and efficacy of medications before they can be marketed to the public. They conduct rigorous review processes that include evaluating clinical trial data submitted by drug manufacturers.

This regulatory oversight is crucial in determining whether a drug meets the necessary standards for public use, especially for life-threatening conditions like AIDS. Therefore, the correct answer reflects the FDA's pivotal role in the approval and regulation of pharmaceutical products in the United States, making it the authoritative body overseeing AZT's introduction into the treatment options for AIDS.
