What does the Prescription Drug Marketing Act (PDMA) regulate?

• A. Sets maximum wholesale price for generics
• B. Prohibits distribution of adulterated, misbranded, or counterfeit drugs; regulates drug samples and marketing to doctors
• C. Regulates only dietary supplements
• D. Oversees pharmacovigilance timelines

Answer: (B)

PDMA focuses on how prescription drugs are marketed and distributed, with a strong emphasis on safeguarding the supply chain and limiting how drug samples reach prescribers. It prohibits distribution of adulterated, misbranded, or counterfeit drugs and sets strict controls on handling drug samples and on marketing activities directed at physicians. In practice, drug samples are tightly regulated and generally limited to licensed practitioners, with required recordkeeping and labeling to prevent diversion or misuse.

This isn’t about setting generic prices, regulating dietary supplements, or defining pharmacovigilance timelines—those areas are handled by other laws and agencies.
