Description
Curator's Comment: description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/8595171

Fadrozole (CGS 16949A) is a tetrahydroimidazole-pyridine derivative is a non-steroidal inhibitor of aromatase. In the third phase of clinical trials it was shown, that this drug has good therapeutic effect as a second-line treatment in postmenopausal women with metastatic breast cancer.
