Final answer:
The Drug Enforcement Administration (DEA) maintains information on the prescribing of schedule II drugs, in coordination with the Food and Drug Administration (FDA), which also regulates drug advertising and promotion.
Step-by-step explanation:
The group responsible for maintaining information related to the prescribing of schedule II drugs is the Drug Enforcement Administration (DEA). The DEA works alongside the Food and Drug Administration (FDA) to monitor the use of controlled substances and ensure compliance with regulations. It is mandatory for healthcare providers to be registered with the DEA to legally prescribe schedule II drugs, and they are required to follow strict reporting and documentation procedures. The FDA's Office of Prescription Drug Promotion (OPDP) additionally reviews and regulates prescription drug advertising and promotion to ensure medications, including schedule II drugs, are marketed accurately and responsibly.
