Etymology: Doxepin is a pharmaceutical coinage, built by chemists rather than shaped over centuries of speech. Its ending comes from "oxepin," the name of a chemical ring structure: a seven-membered ring containing one oxygen atom, the framework that chemists use to name the tricyclic compounds the drug belongs to. The "dox-" at the front is a shortened piece of the drug's full chemical name, a prefix attached so the name would identify the molecule's structure precisely. Because the word was made deliberately in a laboratory naming system, it has no older history in ordinary English or any other language. Its meaning is fixed by the molecule it names: a tricyclic antidepressant, prescribed for depression and, at lower doses, for conditions such as chronic itching. The word tells a pharmacist which family of compounds a medicine belongs to, which is the whole purpose of such a name.

Synonyms: antidepressant, tricyclic, medication, drug, pharmaceutical
