CATEGORIES OF DRUGS

A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes. Pharmaceutical or a drug is classified on the basis of their origin:

- drug from natural origin, or herbal, or plant, or mineral origin; some drug substances are of marine origin

- drug from chemical as well as natural origin, derived from partial herbal and partial chemical synthesis, e.g. steroidal drugs

- drug derived from chemical synthesis

- drug derived from animal origin, e.g. hormones and enzymes

- drug derived from microbial origin, e.g. antibiotics

- drug derived by biotechnology, genetic-engineering technique, e.g. hybridoma

- drug derived from radioactive substances.

Classes of medicine are antipyretics(reducing fever(pyrexia); analgesics (reducing pain (painkillers); antimalarialdrugs (treating malaria); antibiotics (inhibiting germ growth); antiseptics (preventing germ growth near burns, cuts and wounds); mood stabilizers; hormone replacements; oral contraceptives; stimulants; tranquilizers; statins.

The Anatomical Therapeutic Chemical (ATC) classification systemdivides the drugs into different groups according to the organ or system on which they act, and according to their chemical, pharmacological and therapeutic properties. Medicinal products are classified according to the main therapeutic use of their main active ingredient, on the basic principle of assigning only one ATC code for each pharmaceutical formulation (i.e. similar ingredients, strength and pharmaceutical form). A medicinal product can be given more than one ATC code if it is available in two or more strengths or formulations with clearly different therapeutic uses.

A drug can have several names. There is usually a genericname for a drug substance plus one or more brandnames. Generic namesfor drugs are chosen by a variety of official bodies. That means that these names sometimes vary from country to country. For example, the generic name for one common pain medication is acetaminophen in the USA. However in many countries the same drug is called paracetamol.

Drug manufacturers choose the brand names of their products. There can be many brands of a particular drug. A brand name is also sometimes called a “proprietary” name. The brand names are usually easier to say and easier to remember. They may be better known than the generic name.
