AZ HB2089

Prohibits manufacturers and wholesale distributors from engaging in price gouging on essential off-patent or generic drugs, defined as drugs with expired patent protections that are on the WHO essential medicines list or designated as essential by the U.S. Department of Health and Human Services.

Allows the state medical assistance program to notify the attorney general when an essential drug price increases at least 50% in one year and would cost more than $80 for a 30-day supply or full course of treatment at wholesale acquisition cost.

Requires manufacturers to submit a 45-day statement to the attorney general itemizing production costs, access expansion efforts, and any justification for price increases when requested.

Authorizes superior courts to issue orders enjoining violations, restoring consumer money, requiring manufacturers to maintain prior pricing for state assistance program participants for up to one year, and imposing civil penalties up to $10,000 per violation.

Exempts wholesale distributors from price gouging liability if price increases are directly attributable to additional costs imposed by the manufacturer.
