AZ HB2558

Prohibits manufacturers and wholesale distributors from engaging in price gouging on essential off-patent or generic drugs, defined as drugs with expired exclusive marketing rights that are on the WHO essential medicines list or designated by HHS for treating life-threatening or chronic conditions, manufactured by three or fewer companies, and sold in Arizona.

Allows the state medical assistance program to notify the Attorney General of price increases of at least 50 percent within one year if a 30-day supply, full course of treatment, or single dose would cost more than $80 at wholesale acquisition cost.

Requires manufacturers to submit statements within 45 days of Attorney General request explaining cost components, manufacturing increases, and expenditures to expand drug access.

Empowers Superior Court to issue orders restraining violations, restoring consumer money, requiring manufacturers to sell drugs at pre-violation prices for up to one year, and imposing civil penalties of up to $10,000 per violation.

Protects confidentiality of manufacturer-provided commercial information unless waived, and allows the Attorney General to proceed without direct consumer contact in the state.
