Drug nomenclature is the systematic naming of drugs, especially pharmaceutical drugs.In the majority of circumstances, drugs have 3 types of names: chemical names, the most important of which is the IUPAC name; generic or nonproprietary names, the most important of which are international nonproprietary names (INNs); and trade names, which are brand names.

Any chemical substance with biological activity may be considered a drug. This list categorises drugs alphabetically and also by other categorisations. This multi-page article lists pharmaceutical drugs alphabetically by name. Many drugs have more than one name and, therefore, the same drug may be listed more than once.
This list of pharmaceutical compound number prefixes provides codes used by individual pharmaceutical companies when naming their pharmaceutical drug candidates. . Pharmaceutical companies generally produce large numbers of compounds in the research phase for which it is impractical to use often long and cumbersome systematic chemical names, and for which the effort to generate nonproprietary ...

Having unambiguous standard names for each pharmaceutical substance (standardization of drug nomenclature) is important because a drug may be sold under many different brand names, or a branded medication may contain more than one drug. For example, the branded medications Celexa, Celapram and Citrol all contain the same active ingredient whose ...
The main purpose of chemical nomenclature is to disambiguate the spoken or written names of chemical compounds: each name should refer to one compound. Secondarily, each compound should have only one name, although in some cases some alternative names are accepted. Preferably, the name should also represent the structure or chemistry of a compound.
Pliny the Elder, who lived from 23–79 CE, first gave a name to what we now call pills, calling them pilula. [2] Pliny also wrote Naturalis Historia a collection of 38 books and the first pharmacopoea. Pedanius Dioscorides wrote De Materia Medica (c. 40 – 90 CE); this book dominated the area of drug knowledge for some 1500 years until the ...
A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect. [1] Consumption of drugs can be via inhalation , injection , smoking , ingestion , absorption via a patch on the skin, suppository , or dissolution under the tongue .
