title: Antisubstitution law changes and the hospital formulary system.
abstract: The effects of amendments to state antisubstitution laws on the hospital formulary system are discussed. The approaches of four states--California, Michigan, Minnesota and Delaware--are reviewed. It is concluded that the legal basis of the hospital formulary system remains intact regardless of the changes in state antisubstitution laws.
