Abstract:
Under pressure to provide cost-effective healthcare, many healthcare systems have adopted Therapeutic Interchange (TI) programs-the interchange of therapeutically equivalent but chemically unique drugs-to reduce the total cost of therapy without compromising patient care. To be appropriate and feasible, a TI program for any class of drugs must meet certain rigorous criteria and undergo medical, financial, tactical, and legal reviews. Moreover, once a TI program is implemented, a process to monitor its success should be established. Application of the TI criteria to low-molecular-weight heparins (LMWHs) reveals that a blanket TI program for LMWHs does not appear advisable at this time.
