INDICATIONS Anastraol tablets are indicated for adjuvant treatment of postmenopausal women with hormone receptor positive early breast cancer. Anastraol tablets are indicated for the first-line treatment of postmenopausal women with hormone receptor positive or hormone receptor unknown locally advanced or metastatic breast cancer. Anastraol tablets are indicated for the treatment of advanced breast cancer in postmenopausal women with disease progression following tamoxifen therapy. Patients with ER-negative disease and patients who did not respond to previous tamoxifen therapy rarely responded to ARIMIDEX. DOSAGE AND ADMINISTRATION The dose of Anastraol tablets is one 1 mg tablet taken once a day. For patients with advanced breast cancer, Anastraol tablets should be continued until tumor progression. For adjuvant treatment of early breast cancer in postmenopausal women, the optimal duration of therapy is unknown. In the ATAC trial Anastraol tablets was administered for five years. Patients with Hepatic Impairment (See CLINICAL PHARMACOLOGY) Hepatic metabolism accounts for approximately 85% of anastrozole elimination. Although clearance of anastrozole was decreased in patients with cirrhosis due to alcohol abuse, plasma anastrozole concentrations stayed in the usual range seen in patients without liver disease. Therefore, no changes in dose are recommended for patients with mild-to-moderate hepatic impairment, although patients should be monitored for side effects. ARIMIDEX has not been studied in patients with severe hepatic impairment. Patients with Renal Impairment No changes in dose are necessary for patients with renal impairment. Use in the Elderly No dosage adjustment is necessary.
