Arimidex and Femara are nonsteroidals, Aromasin is a steroidal.

I don't like to disagree here with anyone, but Arimidex and Femara are both first-line therapies and Aromasin is second-line therapy (per package insert); patients sometimes ARE changed from one first-line therapy such as Arimidex to another first-line therapy such as Femara before being changed to a second-line therapy such as Aromasin, even though the mechanism of action is more similar between Arimidex and Femara.

Best check directly with a pharmacist, who can take a look at the package insert with you on this.
