A medication is a drug used to diagnose, cure, treat, or prevent disease. Drug therapy (pharmacotherapy) is an important part of the medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate management.
A pharmacist, also known as a chemist or a druggist, is a healthcare professional who specializes in the preparation, dispensing, and management of medications to ensure safe and effective use, while also providing medication counseling and guidance to patients and healthcare providers. Also, pharmacists often serve as primary care providers in the community, and may offer other 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 a physician or other registered healthcare professional 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 recipere, that gave the list of the materials to be compounded.
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 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.
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.
An online pharmacy, internet pharmacy, or mail-order pharmacy is a pharmacy that operates over the Internet and sends orders to customers through mail, shipping companies, or online pharmacy web portal.
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.
Pharmacy in China involves the activities engaged in the preparation, standardization and dispensing of drugs, and its scope includes the cultivation of plants that are used as drugs, the synthesis of chemical compounds of medicinal value, and the analysis of medicinal agents. Pharmacists in China are responsible for the preparation of the dosage forms of drugs, such as tablets, capsules, and sterile solutions for injection. They compound physicians', dentists', and veterinarians' prescriptions for drugs. Pharmacological activities are also closely related to pharmacy in China.
A pharmacy is a retail shop which provides pharmaceutical drugs, among other products. At the pharmacy, a pharmacist oversees the fulfillment of medical prescriptions and is available to counsel patients about prescription and over-the-counter drugs or about health problems and wellness issues. A typical pharmacy would be in the commercial area of a community.
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.
Online doctor is a term that emerged during the 2000s, used by both the media and academics, to describe a generation of physicians and health practitioners who deliver healthcare, including drug prescription, over the internet.
Deprescribing is described as a patient-centred process to taper or stop medications with the intention to achieve improved health outcomes by reducing exposure to medications that are potentially either harmful or no longer required. Deprescribing is important to consider with changing health and care goals over time, as well as polypharmacy and adverse effects. Deprescribing can improve adherence, cost, and health outcomes but may have adverse drug withdrawal effects. More specifically, deprescribing is the planned and supervised process of intentionally stopping a medication or reducing its dose to improve the person's health or reduce the risk of adverse side effects. Deprescribing is usually done because the drug may be causing harm, may no longer be helping the patient, or may be inappropriate for the individual patient's current situation. Deprescribing can help correct polypharmacy and prescription cascade.
Antimicrobial stewardship is the systematic effort to educate and persuade prescribers of antimicrobials to follow evidence-based prescribing, in order to stem antimicrobial overuse, and thus antimicrobial resistance. AMS has been an organized effort of specialists in infectious diseases, both in Internal Medicine and Pediatrics with their respective peer-organizations, hospital pharmacists, the public health community and their professional organizations since the late 1990s. It has first been implemented in hospitals. In the U.S., within the context of physicians' prescribing freedom, AMS had largely been voluntary self-regulation in the form of policies and appeals to adhere to a prescribing self-discipline until 2017, when the Joint Commission prescribed that hospitals should have an Antimicrobial Stewardship team, which was expanded to the outpatient setting in 2020.
Pharmacy in the United Kingdom has been an integral part of the National Health Service since it was established in 1948. Unlike the rest of the NHS, pharmacies are largely privately provided apart from those in hospitals, and even these are now often privately run.
Separation of prescribing and dispensing, also called dispensing separation, is a practice in medicine and pharmacy in which the physician who provides a medical prescription is independent from the pharmacist who provides the prescription drug.
Drug utilization review refers to a review of prescribing, dispensing, administering and ingesting of medication. This authorized, structured and ongoing review is related to pharmacy benefit managers. Drug use/ utilization evaluation and medication utilization evaluations are the same as drug utilization review.
