A medicine or drug is any substance or combination of substances administered to human beings or animals to treat or prevent disease; alternatively to assist in medical diagnosis. Medication, a word more widely used to mean the act of administering medicine, is used in the health industry as a synonym for the word "medicine" itself. Commercial medicines or medications are produced by pharmaceutical companies and are often patented. Copies of former patented drugs are called generic drugs.
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). The types of medicines:
1)Antipyretics : Reducing fever.
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.

A 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.
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.
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.
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.
