Translations

Medication, also referred to as medicine, is usually a drug or any other substance used to prevent or cure disease or to relieve pain, anxiety or any form of perceived discomfort, such as hunger. Medication is often used to mean the act of administering medicines or drugs. Other synonyms include pharmacotherapy, pharmacotherapeutics, drug treatment. Drug treatment, that is: The administration of drugs with therapeutic intention, usually characterizes and distinguishes the practice of Medicine (and the Medical Specialties) from the art of Surgery (and its derived Surgical Specialties). This practical (more than theoretical) distintcion if deeply rooted in the History of Medicine. The science of administering drugs to humans in the clinical setting is termed clinical pharmacology. The emphasis on drug treatment plays an essential role in distinguishing medical from surgical practice.

Classification

Medication can be usually classified in various ways, e.g. by its chemical properties, mode of administration, or biological system affected. An elaborate and widely used classification system is the Anatomical Therapeutic Chemical Classification System (ATC system).

Types of medicines:

1. Antipyretics : reducing fever (pyrexia)
2. Analgesics : painkillers
3. Anti-malarial drugs : treating malaria
4. Antibiotics : inhibiting germ growth
5. Antiseptics : prevention of germ growth near burns, cuts and wounds

For euthanasia

An euthanaticum is used for euthanasia and physician-assisted suicide, see also barbiturates.

Euthanasia is not permitted by law in many countries, and consequently medicines will not be licenesed for this use in those countries.

Legal considerations

Medications may be divided into over-the-counter drugs (OTC) which may be available without special restrictions, and prescription only medicine (POM), which must be prescribed by a licensed medical practitioner. The precise distinction between OTC and prescription depends on the legal jurisdiction.

The International Narcotics Control Board of the United Nations imposes a world law of prohibition of certain medications. They publish a lengthy list of chemicals and plants whose trade and consumption (where applicable) is forbidden. OTC medications are sold without restriction as they are considered safe enough that most people will not hurt themselves accidentally by taking it as instructed. Many countries, such as the United Kingdom have a third category of pharmacy medicines which can only be sold in registered pharmacies, by or under the supervision of a pharmacist.

Other/related topics

Polypharmacy: suggests that multiple use of prescribed and non-prescribed medications, (use of 5 or more), can have adverse effects on the recipient.

Zoopharmacognosy: Animal usage of drugs and non-foods.

Blockbuster drug

A blockbuster drug is a drug generating more than $1 billion of revenue for its owner each year. The search for blockbusters has been the foundation of the R&D strategy adopted by big pharmaceutical companies, but this looks set to change. New advances in genomics, and the promise of personalized medicine, are likely to fragment the pharmaceutical market.

A recent report from Urch Publishing estimated that about one third of the pharma market by value is accounted for by blockbusters. About 100 products are blockbusters. The top seller was Lipitor, a cholesterol-lowering medication marketed by Pfizer with sales of $12.2 billion.
