The British National Formulary (BNF) is a United Kingdom (UK) pharmaceutical reference book that contains a wide spectrum of information and advice on prescribing and pharmacology, along with specific facts and details about many medicines available on the UK National Health Service (NHS). Information within the BNF includes indication(s), contraindications, side effects, doses, legal classification, names and prices of available proprietary and generic formulations, and any other notable points. Though it is a national formulary, it nevertheless also includes entries for some medicines which are not available under the NHS, and must be prescribed and/or purchased privately. A symbol clearly denotes such drugs in their entry.
Over-the-counter (OTC) drugs are medicines sold directly to a consumer without a requirement for a prescription from a healthcare professional, as opposed to prescription drugs, which may be supplied only to consumers possessing a valid prescription. In many countries, OTC drugs are selected by a regulatory agency to ensure that they contain ingredients that are safe and effective when used without a physician's care. OTC drugs are usually regulated according to their active pharmaceutical ingredient (API) and strengths of final products.
A pharmacist, also known as a chemist in Commonwealth English, is a healthcare professional who is knowledgeable about preparation, mechanism of action, clinical usage and legislation of medications in order to dispense them safely to the public and to provide consultancy services. A pharmacist also often serves as a primary care provider in the community and offers services, such as health screenings and immunizations.
Pharmacy is the science and practice of discovering, producing, preparing, dispensing, reviewing and monitoring medications, aiming to ensure the safe, effective, and affordable use of medicines. It is a miscellaneous science as it links health sciences with pharmaceutical sciences and natural sciences. The professional practice is becoming more clinically oriented as most of the drugs are now manufactured by pharmaceutical industries. Based on the setting, pharmacy practice is either classified as community or institutional pharmacy. Providing direct patient care in the community of institutional pharmacies is considered clinical pharmacy.
A prescription, often abbreviated ℞ or Rx, is a formal communication from physicians or other registered healthcare professionals to a pharmacist, authorizing them to dispense a specific prescription drug for a specific patient. Historically, it was a physician's instruction to an apothecary listing the materials to be compounded into a treatment—the symbol ℞ comes from the first word of a medieval prescription, Latin recipe, that gave the list of the materials to be compounded.
Prescription drug list prices in the United States continually are among the highest in the world. The high cost of prescription drugs became a major topic of discussion in the 21st century, leading up to the American health care reform debate of 2009, and received renewed attention in 2015. One major reason for high prescription drug prices in the United States relative to other countries is the inability of government-granted monopolies in the American health care sector to use their bargaining power to negotiate lower prices, and the American payer ends up subsidizing the world's R&D spending on drugs.
A prescription drug is a pharmaceutical drug that is permitted to be dispensed only to those with a medical prescription. In contrast, over-the-counter drugs can be obtained without a prescription. The reason for this difference in substance control is the potential scope of misuse, from drug abuse to practicing medicine without a license and without sufficient education. Different jurisdictions have different definitions of what constitutes a prescription drug.
The pregnancy category of a medication is an assessment of the risk of fetal injury due to the pharmaceutical, if it is used as directed by the mother during pregnancy. It does not include any risks conferred by pharmaceutical agents or their metabolites in breast milk.
The Pharmaceutical Benefits Scheme (PBS) is a program of the Australian Government that subsidises prescription medication for Australian citizens and permanent residents, as well as international visitors covered by a reciprocal health care agreement. The PBS is separate to the Medicare Benefits Schedule, a list of health care services that can be claimed under Medicare, Australia's universal health care insurance scheme.
Pharmaceutical marketing is a branch of marketing science and practice focused on the communication, differential positioning and commercialization of pharmaceutical products, like specialist drugs, biotech drugs and over-the-counter drugs. By extension, this definition is sometimes also used for marketing practices applied to nutraceuticals and medical devices.
Tizanidine, sold under the brand name Zanaflex among others, is an alpha-2 (α2) adrenergic receptor agonist, similar to clonidine, that is used to treat muscle spasticity due to spinal cord injury, multiple sclerosis, and spastic cerebral palsy. Effectiveness appears similar to baclofen or diazepam. It is taken by mouth.
BNF for Children (BNFC) is the standard UK paediatric reference for prescribing and pharmacology.
An essential medicines policy is one that aims at ensuring that people get good quality drugs at the lowest possible price, and that doctors prescribe the minimum of required drugs in order to treat the patient's illness. The pioneers in this field were Sri Lanka and Chile.
The Sri Lanka National Pharmaceuticals Policy was established in the 1970s following the submission of a report by Dr S.A. Wickremasinghe and Prof. Seneka Bibile. It aimed at ensuring that people get good quality drugs at the lowest possible price and that doctors would prescribe the minimum required drugs to treat the patient's illness. It was a pioneer in the field of rational National pharmaceuticals policy.
The State Pharmaceuticals Corporation (SPC) is a state-owned enterprise with its headquarters in Colombo, Sri Lanka. It is the largest supplier of drugs in the country, and is tasked with providing quality-assured health care items that are safe and effective, at an affordable price, while educating the public on the rational use of drugs. It employees about 600 staff.
The Compendium of Pharmaceuticals and Specialties: The Canadian Drug Reference for Health Professionals, more commonly known by its abbreviation CPS, is a reference book that contains drug monographs and numerous features which help healthcare professionals prescribe and use drugs safely and appropriately. A print version of CPS is released annually by the Canadian Pharmacists Association (CPhA). The CPhA is a nonprofit organization that advocates for pharmacists in Canada. An external Editorial Advisory Committee of Canadian physicians and pharmacists advises CPhA about the strategic direction of their publications including CPS. CPS is also available online by subscription at www.pharmacists.ca. Most of the drug monographs in CPS are provided by manufacturers, though numerous monographs—usually for drugs which are available as generic brands— are written by CPhA editorial staff and peer reviewed. 2010 marked the 50th anniversary of the first edition of CPS.
Pharmaceutical policy is a branch of health policy that deals with the development, provision and use of medications within a health care system. It embraces drugs, biologics, vaccines and natural health products.
Medication costs, also known as drug costs are a common health care cost for many people and health care systems. Prescription costs are the costs to the end consumer. Medication costs are influenced by multiple factors such as patents, stakeholder influence, and marketing expenses. A number of countries including Canada, parts of Europe, and Brazil use external reference pricing as a means to compare drug prices and to determine a base price for a particular medication. Other countries use pharmacoeconomics, which looks at the cost/benefit of a product in terms of quality of life, alternative treatments, and cost reduction or avoidance in other parts of the health care system. Structures like the UK's National Institute for Health and Clinical Excellence and to a lesser extent Canada's Common Drug Review evaluate products in this way.
A formulary is a list of pharmaceutical drugs, often decided upon by a group of people, for various reasons such as insurance coverage or use at a medical facility. Traditionally, a formulary contained a collection of formulas for the compounding and testing of medication. Today, the main function of a prescription formulary is to specify particular medications that are approved to be prescribed at a particular hospital, in a particular health system, or under a particular health insurance policy. The development of prescription formularies is based on evaluations of efficacy, safety, and cost-effectiveness of drugs.
Electronic prescription is the computer-based electronic generation, transmission, and filling of a medical prescription, taking the place of paper and faxed prescriptions. E-prescribing allows a physician, physician assistant, pharmacist, or nurse practitioner to use digital prescription software to electronically transmit a new prescription or renewal authorization to a community or mail-order pharmacy. It outlines the ability to send error-free, accurate, and understandable prescriptions electronically from the healthcare provider to the pharmacy. E-prescribing is meant to reduce the risks associated with traditional prescription script writing. It is also one of the major reasons for the push for electronic medical records. By sharing medical prescription information, e-prescribing seeks to connect the patient's team of healthcare providers to facilitate knowledgeable decision making.
