Which of the following statements is true regarding the transfer of controlled substances between pharmacies?

The correct use of inventory reporting during the transfer of controlled substances between pharmacies is governed by regulations to ensure proper tracking and accountability of these substances. When controlled substances are transferred, it is required that an inventory be accurately documented and filed with the Board within a specific timeframe—ten days in this case—after the transfer has occurred. This process helps maintain oversight and regulatory compliance intended to prevent misuse and ensure that controlled substances are accounted for during transfers.

Maintaining an inventory is crucial as it provides transparency to regulatory bodies regarding the movement of controlled substances and allows for audits if necessary. This requirement aims to ensure that both the transferring and receiving pharmacies are held responsible for the drugs being exchanged.

The other options reflect misunderstandings about the regulations surrounding the transfer of controlled substances. For example, the requirement for prior notification, the assertion that inventories are not needed, and that transfers can occur without any formal notification all do not align with best practices in pharmacy law and ensure proper monitoring of controlled substances. Each of these alternatives fails to emphasize the importance of regulation and accountability in the handling of these sensitive medications.
