Erleada is Apalutamide; Eligard is Leuprorelin (an older ADT treatment that's been around since the 1980s).

Zytiga (Abiraterone acetate) is also an older treatment, from the 1990s, generally used with both ADT and a steroid.

Use those online comparisons with extreme caution (or, better, just ignore them). Our oncology teams work hard to find the right treatment for each of us in our unique cancer situations, but even if those meds were all interchangeable for everyone, 3% would be well within any margin of error anyway (I wouldn't pay attention to any difference that's not well into the double digits).
