GoodRx has been hit with a series of antitrust class actions in California and Rhode Island federal courts challenging the company’s partnerships with pharmacy benefit managers including CVS, Express Scripts, MedImpact and Navitus.

The plaintiff pharmacies alleged that GoodRx, a prescription discount card aggregator, and four of the largest pharmacy benefit managers (PBMs) engaged in a conspiracy to fix prices paid to pharmacies for reimbursement of prescription drug claims.
