Final answer:
All purchases of pharmaceuticals at an institution are reviewed by an IRB or IACUC, which ensure safety and ethical standards are maintained. The FDA also regulates medicines to protect public health.
Step-by-step explanation:
All purchases of pharmaceuticals in an institution should be reviewed by the Institutional Review Board (IRB) or Institutional Animal Care and Use Committee (IACUC), depending on the context. IACUCs are necessary at institutions that use animals and receive federal funding to ensure compliance with NIH guidelines, while IRBs review experimental proposals that involve human participants. Both are important for maintaining the safety and efficacy of medical treatments and ensuring ethical standards are met in research. Furthermore, the Food and Drug Administration (FDA) also plays a crucial role in this process by regulating the medicines that pharmacies can sell, which involves extensive drug testing to protect the public from unsafe drugs.
