What did the Prescription Drug Marketing Act (PDMA) of 1987 primarily require regarding verification of drug sources?
Answer
Wholesalers to maintain records verifying the legitimate source of drugs
The Prescription Drug Marketing Act (PDMA) of 1987 established an early regulatory milestone focusing on drug diversion. Although it was not a complete serialization mandate, the PDMA specifically placed accountability further down the distribution channel by requiring wholesalers to keep thorough records that verified the legitimacy and source of the drugs they handled. This action began the process of shifting the responsibility for proof of origin onto the supply chain partners involved in distribution, preceding the more comprehensive electronic tracing requirements developed later.
