The Medicaid Drug Rebate Program (MDRP) requires pharmaceutical manufacturers to issue rebates to Medicaid for covered outpatient drugs. When they offer prescription drug  benefits, Medicaid programs must cover nearly all drugs, potentially reducing Medicaid’s leverage to negotiate discounts. Policymakers created the MDRP in response to rising drug costs and to help ensure Medicaid receives comparable discounts to other payers in the market.
