Controlled drugs listed in Part __ of pharmacy records must be maintained in a dedicated book or register.

Controlled drugs listed in Part 1 of pharmacy records must be maintained in a dedicated book or register because these records are specifically required by the regulations governing controlled substances. Part 1 typically deals with the strictest categories of controlled drugs that require meticulous record-keeping to ensure compliance with legal and regulatory standards.

By maintaining these records in a dedicated book or register, pharmacies can easily track the acquisition and dispensing of these substances, thereby preventing misuse and ensuring accountability. This dedicated record helps to create a clear audit trail, which is essential for regulatory inspections and for the pharmacy's internal management, ensuring safe and proper handling of potentially dangerous medications.

In contrast, other sections like Parts 2, 3, and 4 focus on different categories of drugs or provide less stringent requirements for record-keeping. These parts might allow for more flexibility regarding how records are maintained, but for Part 1, the requirement for a dedicated register reflects the heightened risk and regulatory scrutiny associated with those controlled substances.
