A formulary is a list of pharmaceutical drugs that are approved to be prescribed at a hospital or under a particular health insurance policy. The list is often decided upon by a group of people, such as pharmacists, physicians, nurses, and administrators, who form a Pharmacy and Therapeutics (P&T) committee. The P&T committee is responsible for developing, managing, and updating the formulary, taking into account factors such as efficacy, safety, cost-effectiveness, and clinical information. The formulary helps to guide medical professionals in selecting the most appropriate medications for different diseases, conditions, and patients, with the goal of optimizing pharmacological utility for a specific population. For example, a formulary might indicate the optimal dosage and duration of intravenous antibiotic use based on scientific literature and local experience.

A formulary is a list of pharmaceutical drugs
The main function of a prescription formulary is to specify which medications are approved for prescription in a particular hospital, health system, or under a particular insurance plan. For example, in the UK's National Health Service (NHS), formularies outline which drugs are available on the NHS, with the British National Formulary (BNF) and the Drug Tariff serving as the main reference sources. In Australia, the Pharmaceutical Benefits Scheme (PBS) subsidises medications, and the PBS webpage and Australian Medicines Handbook provide information on which medications are available under the scheme.
Formularies are designed to promote clinically sound and cost-effective medication therapy, and they can help manage drug costs imposed on insurance policies. Patients typically pay a larger percentage of the cost for drugs that are not included in the formulary. While formularies provide guidance, they do not dictate the treatment plan for individual patients, and physicians may prescribe non-formulary medicines if deemed necessary and justifiable.
Formularies also contain valuable clinical information such as side effects, contraindications, and dosage guidelines. They are living documents that evolve as new information and resources become available. Overall, formularies play a crucial role in ensuring the safe, effective, and affordable utilisation of medications within healthcare systems.

Formularies are decided upon by a group of people
A hospital formulary is a list of medications and related products that is used to optimise pharmacological utility for a given patient population. For example, a formulary might indicate the optimal dosage and duration of intravenous antibiotic use for post-operative bowel surgery patients.
The composition and structure of this group can greatly affect both the process and outcome of the formulary system. For example, the inclusion of nurses, legal experts, and administrators on the committee can bring a different perspective to medication use and ensure that decisions are made with a range of factors in mind, including cost, quality of life, and drug interactions.
Comparative studies are crucial to making the best formulary decisions, as they allow for the comparison of similar agents in a therapeutic class. This can help to identify the most effective drugs, which should be the first ones used to manage a particular condition. For example, in the case of seizures, valproate was found to be more effective for generalized seizures, while lamotrigine was more effective for partial seizures. However, all drugs in the study produced adverse effects in a large fraction of patients, so quality of life and adverse effects must also be considered when making formulary decisions.
Additionally, the long-term safety of new drugs should be a critical decision point regarding formulary addition. When new drugs are similar to existing drugs on a formulary, criteria for use can be developed to allow for a rational approach to their use. For example, a new drug may be used when another agent is not effective or not tolerated.

Formularies help manage drug costs imposed on insurance policies
A formulary is a list of pharmaceutical drugs, which specifies the particular medications that are approved to be prescribed at a particular hospital, in a particular health system, or under a particular health insurance policy. Formularies are often decided upon by a group of people, such as a Pharmacy and Therapeutics (P&T) committee, which consists of pharmacists, physicians, nurses, and administrators. The P&T committee is responsible for developing, managing, updating, and administering the formulary. They compare medications by therapeutic classifications and clinical use, selecting the safest and most effective medications that will produce the desired therapeutic goals at a reasonable cost to the healthcare system.
In some cases, patients may be responsible for a larger percentage of the cost of a drug if it is not included in the formulary, which can be a significant financial burden. Formularies can also cause issues when patients are discharged from the hospital if they are not aligned with outpatient drug insurance plans. However, formularies are not absolutely binding, and physicians may prescribe non-formulary medicines if they are considered necessary and justifiable.
Overall, formularies play an important role in managing drug costs imposed on insurance policies by providing a list of approved medications that are safe, effective, and cost-effective, while also allowing for flexibility in cases where non-formulary medications are required. By using formularies, healthcare providers can promote clinically sound and affordable medication therapy, improve patient access to affordable care, and enhance their quality of life.

Formularies are not binding, physicians may prescribe non-formulary medicine
A hospital formulary is a list of prescription medications that are covered by a given insurance plan. Formularies are designed to optimise pharmacological utility for a given population, such as post-operative bowel surgery patients. They do not dictate treatment plans for individual patients. For example, a formulary might indicate the optimal dosage and duration of intravenous antibiotic use based on available scientific literature and local experience. However, the clinician will then appraise whether the individual characteristics of a patient qualify for an exception to the global selection.
Formularies are not binding, and physicians may prescribe non-formulary medicine. Non-formulary drugs are medications that are not included on a given plan's list of covered prescription drugs. There are several reasons why a physician might prescribe a non-formulary drug. For example, a patient's individual characteristics may require a different medication than what is indicated on the formulary. In other cases, a non-formulary drug may be more effective than the formulary alternatives. Additionally, formularies are often not up-to-date, and new drugs that are more effective may not yet be included.
If a physician prescribes a non-formulary medication, they can submit a formulary exception to the insurer, explaining why the drug is necessary for the patient's treatment. Factors such as medical necessity, failure of covered alternatives, and supporting evidence can strengthen these requests. If the request is denied, the physician can assist in appealing the decision to ensure the patient receives the necessary medication at an affordable cost.
While formularies are designed to guide prescribing decisions and improve medicine safety and efficiency, they are not always followed. Studies have shown that up to 70% of non-formulary drug usage is inappropriate or does not follow the prescribed policies. This may be due to a lack of awareness or understanding of formulary management among physicians, or it may be due to the belief that their decisions as experts in their field are justified. Educating stakeholders, including physicians, patients, and carers, on formulary management is essential to mitigate the pressures placed on physicians to prescribe non-formulary medications.

Formularies are based on evaluations of efficacy, safety, and cost-effectiveness
A formulary is a list of prescription drugs covered by a prescription drug plan or insurance plan. Formularies are often decided by a group of people, such as an expert panel, for reasons such as insurance coverage or use at a medical facility. In the context of a hospital or health system, a formulary aims to optimise pharmacological utility for a specific patient population, such as post-operative bowel surgery patients. It does not dictate individual treatment plans but guides the selection of agents most likely to achieve a successful outcome. For instance, in the case of preventing surgical site infections (SSI), a formulary would recommend antibiotics and combinations ranked by their likelihood of success.
The development of prescription formularies is based on evaluations of efficacy, safety, and cost-effectiveness. Efficacy refers to the capacity of an intervention to produce a particular benefit under ideal conditions, typically measured through controlled clinical trials. Effectiveness, on the other hand, considers the capacity to produce benefits in real-world settings, taking into account patient-centred outcomes such as how patients feel, function, or survive. Safety evaluations involve assessing the likelihood and type of adverse effects, initially through preclinical research in human cell cultures or animal models.
Randomised controlled trials (RCTs) are considered the gold standard for evaluating treatment effects, but they may not always be generalisable due to factors like patient characteristics, condition specifics, and costs. Phase 2 and 3 trials assess efficacy and side effects, while Phase 4 trials, conducted after drug approval, can detect uncommon adverse effects in larger populations, including special subpopulations like pregnant women or children.
The inclusion of drugs in a formulary considers their relative advantages and disadvantages, availability, and cost-effectiveness. Formularies can help manage drug costs for insurance policies, as patients typically pay a larger percentage for non-formulary drugs. They provide financial incentives for patients to choose lower-cost drugs and encourage generic substitution. However, formulary misalignment with outpatient drug insurance plans can cause issues when patients are discharged.
In summary, formularies are based on rigorous evaluations of efficacy, safety, and cost-effectiveness, utilising clinical trials, expert opinions, and real-world considerations to guide drug selection and optimise patient outcomes while managing drug costs.
