Aromatise Inhibitors

[Rupali]

Hi all,
I have been on tamoxifen for 2 years and now my onc is moving me t Aroomasin. I read Aromasin is a steroidal AI where as the others like Femara are non steroidal....DO u know what is the difference between the two and which is more easy to tolerate. Why is is called steroidal AI?
Regards,
Rupali
