A closed formulary is a list of medications that a hospital or health organization has approved for use. It limits the options available in a drug class in order to control expenses. By limiting the number of medications they carry, hospitals can negotiate lower prices and ensure the availability of essential drugs.

These institutions carefully select medications based on cost-effectiveness and clinical effectiveness to provide the best care for their patients while being fiscally responsible.
