Antihistamines are a class of medications commonly used to relieve allergy symptoms by blocking the action of histamine, a substance in the body that causes allergic reactions. A key characteristic of many antihistamines is that their generic names often end with the suffix "-ine." This is true for well-known examples such as diphenhydramine and cetirizine, which are widely recognized as antihistamines.

The "-ine" suffix is not exclusive to antihistamines, as it can also be found in other classes of drugs, but it is a frequently observed pattern in the names of antihistamines. Recognizing this suffix can aid in identifying antihistamines in pharmacology and is an important aspect of understanding medication naming conventions.
