This bill establishes prescription drug pricing disclosure requirements and measures to reduce prescription drug costs. It requires pharmacy benefits managers (PBMs) to disclose information about prescription drug and biological product pricing and generic substitutions to benefit plan purchasers. It also requires PBMs to provide a toll-free number for consumers and pharmacists to quickly obtain coverage, pricing, and safety information. The bill creates the Prescription Drug and Biological Product Review Commission to develop a list of critical drugs and biological products, and requires manufacturers to report information on the costs of producing and marketing these products. The commission can set maximum allowable prices for drugs and biological products it deems excessively costly. The bill also prohibits manufacturers and wholesale distributors from engaging in price gouging on essential off-patent or generic drugs and biological products, and gives the Attorney General authority to investigate and take enforcement action against price gouging.
