| Synonyms | |
| Therapy Description |
Arimidex (anastrozole) is an aromatase inhibitor, which inhibits estrogen synthesis (PMID: 29719441). Arimidex (anastrozole) is FDA approved for postmenopausal women with hormone receptor-positive early breast cancer or advanced patients who have failed tamoxifen therapy (FDA.gov). |
Filtering
- Case insensitive filtering will display rows if any text in any cell matches the filter term
- Use simple literal full or partial string matches
- Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
- Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
- Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")
Sorting
- Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
- Click on any column header arrows to sort by that column
- Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
