In a closed formulary system, which type of medications are physicians restricted to prescribe?

In a closed formulary system, physicians are restricted to prescribing only those medications that are specifically listed on the hospital formulary. This type of formulary is characterized by its selectivity; only the medications that have been reviewed and approved by a pharmacy and therapeutics committee are included. Physicians must adhere to this list when choosing medications for their patients, which helps ensure that the chosen drugs are proven to be safe, effective, and cost-efficient for the facility's patient population.

This system is advantageous for managing costs, ensuring quality of care, and simplifying the medication management process within the healthcare setting. It provides a structured approach to pharmacotherapy, making it easier for both physicians and pharmacists to work within a predetermined set of medications while still meeting the needs of patients to a significant extent.
