Etymology: Vardenafil is a pharmaceutical coinage, built to name a drug rather than to describe anything in nature. Its name is assembled from pieces: the "-afil" ending is a standardized suffix that drug-naming authorities assign to a family of compounds that inhibit phosphodiesterase type 5 (PDE5), an enzyme that breaks down a chemical signal involved in relaxing blood vessels. Drugs in this family share the "-afil" ending, which signals to prescribers that they belong together, and the drug's name is completed by a stem that distinguishes this particular molecule from its relatives. The rest of the name is more arbitrary, since the stem "varden-" was chosen to be unique and easy to pronounce across languages rather than to carry a meaning. Like most brand-era pharmaceutical names, the word has no older ancestor in any natural language, so its story is one of deliberate construction rather than gradual change. Its meaning has stayed fixed since it was devised: a specific compound used to treat erectile dysfunction.

Synonyms: levitra, erectile dysfunction drug
