Medication
From Wikipedia, the free encyclopedia
A medication is a licenced drug taken to cure or reduce symptoms of an illness or medical condition. Medications are generally divided into two groups by the United States and similar laws -- Over-the-counter drug (OTC) medications, which are available in pharmacies and supermarkets without special restrictions, and Prescription only medicines (POM), which must be prescribed by a physician, physician assistant, nurse practitioner, or dentist. The International Narcotics Control Board of the United Nations imposes a world law of prohibition or censorship of certain medications. They publish a lengthy list of chemicals and plants whose trade and consumption (where applicable) is forbidden. Most OTC medication is generally considered to be safe enough that most persons will not hurt themselves accidentally by taking it as instructed. Many countries, such as the UK have a third category of pharmacy medicines which can only be sold in registered pharmacies, by or under the supervision of a pharmacist. However, the precise distinction between OTC and prescription depends on the legal jurisdiction. Medications are typically produced by pharmaceutical companies and are often patented. Those that are not patented are called generic drugs.
[edit] Medication guide
Medication guide is given by the pharmacist with every prescription. It generally includes description, clinical pharmacology (pharmacokinetics, pharmacodynamics), clinical trials, indications and usage, contraindications, warnings, precautions, adverse reactions, dosage and administration, overdosage, how supplied, storage, revision date and manufacturer and distributor.
[edit] 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.
