What does steroidal mean?
Steroidal is an adjective meaning related to steroids, including steroid hormones and many medicines that act through the body’s steroid pathways. It appears frequently in medical and biological contexts, as in “steroidal anti-inflammatory,” “steroidal treatment,” and “steroidal hormone.” The word can describe the chemical nature of a substance or an effect associated with steroid activity. Because many steroid medicines can produce significant side effects, especially when used for long periods, “steroidal” sometimes carries a cautious or clinical implication. It should not be confused with “nonsteroidal,” which identifies medicines or compounds that work through other mechanisms. Steroidal is also broader than a reference to anabolic steroids specifically: it can refer to substances such as cortisol, aldosterone, and sex hormones, as well as medicines based on steroid structures.

Where does steroidal come from?
The word is formed in English by adding the suffix -al to the related term “steroid,” producing an adjective meaning “pertaining to” or “of the nature of” steroids. The steroid name itself is associated with Greek stereos, meaning “solid,” combined with the scientific suffix -oid. The terminology developed within modern chemistry and biology as researchers identified a group of complex molecules with related chemical structures and major roles in living organisms.
