Case History
Litigation Content
Why this Matters:
The plaintiffs argue that a Colorado law that requires some drug manufacturers to reimburse or resupply pharmacies following certain purchases of a drug violates the Takings Clause of the Fifth Amendment. Such laws are one approach states are currently pursuing to lower prescription drug costs for their residents.
Potential Impact:
The inability for state policymakers to address prescription drug affordability could negate savings for patients, and more broadly restrict state regulatory authority in the health care arena.
