Final answer:
Yes, a drug formulary can change over time, as new drugs are added and other drugs are removed based on new medical research, changes in safety and efficacy, or changes in patent status.
Step-by-step explanation:
Will a drug formulary change over time? The correct answer is 1) Yes, a drug formulary may change over time due to new drugs being added or removed. This change can happen for various reasons, such as new drug development, changes in clinical guidelines, the emergence of new evidence regarding a drug's efficacy or safety, or a change in a drug's patent status. A drug formulary is a list of prescription medications that are covered by a prescription drug plan or another insurance plan. The Center for Drug Evaluation and Research (CDER) ensures that drugs, both new and existing, are safe and effective.
For instance, new drugs go through a rigorous New Drug Application (NDA) process before FDA approval and are evaluated for safety and efficacy. With the advancement of medical research and the release of new data, drugs may be added to a formulary. Conversely, drugs can also be removed if they are found to be less effective than previously thought, unsafe, or if a more cost-effective alternative becomes available.
