Aromasin 25mg Tablet

Exemestane tablets are an aromatase inhibitor indicated for: adjuvant treatment of postmenopausal women with estrogen-receptor positive early breast cancer who have received two to three years of tamoxifen and are switched to Exemestane tablets for completion of a total of five consecutive years of adjuvant hormonal therapy. treatment of advanced breast cancer in postmenopausal women whose disease has progressed following tamoxifen therapy. Adjuvant Treatment of Postmenopausal Women Exemestane tablets are indicated for adjuvant treatment of postmenopausal women with estrogen-receptor positive early breast cancer who have received two to three years of tamoxifen and are switched to Exemestane tablets for completion of a total of five consecutive years of adjuvant hormonal therapy. Advanced Breast Cancer in Postmenopausal Women Exemestane tablets are indicated for the treatment of advanced breast cancer in postmenopausal women whose disease has progressed following tamoxifen therapy.

Reductions in bone mineral density (BMD) over time are seen with Exemestane use. Routine assessment of 25-hydroxy vitamin D levels prior to the start of aromatase inhibitor treatment should be performed. Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception. Reductions in Bone Mineral Density (BMD) Reductions in bone mineral density (BMD) over time are seen with Exemestane use. Table 1 describes changes in BMD from baseline to 24 months in patients receiving Exemestane compared to patients receiving tamoxifen (IES) or placebo. Concomitant use of bisphosphonates, vitamin D supplementation, and calcium was not allowed. Table 1. Percent Change in BMD from Baseline to 24 months, Exemestane vs. Control 1 IES 027 BMD Exemestane N=29 Tamoxifen 1 N=38 Exemestane N=59 Placebo 1 N=65 Lumbar spine (%) -3.1 -0.2 -3.5 -2.4 Femoral neck (%) -4.2 -0.3 -4.6 -2.6 During adjuvant treatment with Exemestane, women with osteoporosis or at risk of osteoporosis should have their bone mineral density formally assessed by bone densitometry at the commencement of treatment. Monitor patients for bone mineral density loss and treat as appropriate. Vitamin D Assessment Routine assessment of 25-hydroxy vitamin D levels prior to the start of aromatase inhibitor treatment should be performed, due to the high prevalence of vitamin D deficiency in women with early breast cancer (EBC). Women with vitamin D deficiency should receive supplementation with vitamin D. Administration with Estrogen-Containing Agents Exemestane tablets should not be coadministered with systemic estrogen-containing agents as these could interfere with its pharmacologic action. Laboratory Abnormalities In patients with early breast cancer, the incidence of hematological abnormalities of Common Toxicity Criteria (CTC) grade ≥1 was lower in the Exemestane treatment group, compared with tamoxifen. Incidence of CTC grade 3 or 4 abnormalities was low (approximately 0.1%) in both treatment groups. Approximately 20% of patients receiving Exemestane in clinical studies in advanced breast cancer experienced CTC grade 3 or 4 lymphocytopenia. Of these patients, 89% had a pre-existing lower grade lymphopenia. Forty percent of patients either recovered or improved to a lesser severity while on treatment. Patients did not have a significant increase in viral infections, and no opportunistic infections were observed. Abridged from the full prescribing information.

The following clinically significant adverse reactions are described elsewhere in the labeling: Reductions in Bone Mineral Density (BMD) Early breast cancer: Adverse reactions occurring in ≥10% of patients in any treatment group (Exemestane tablets vs. tamoxifen) were hot flushes (21% vs. 20%), fatigue (16% vs. 15%), arthralgia (15% vs. 9%), headache (13% vs. 11%), insomnia (12% vs. 9%), and increased sweating (12% vs. 10%). Discontinuation rates due to AEs were similar between Exemestane tablets and tamoxifen (6% vs. 5%). Incidences of cardiac ischemic events (myocardial infarction, angina, and myocardial ischemia) were Exemestane tablets 1.6%, tamoxifen 0.6%. Incidence of cardiac failure: Exemestane tablets 0.4%, tamoxifen 0.3%. Advanced breast cancer: Most common adverse reactions were mild to moderate and included hot flushes (13% vs. 5%), nausea (9% vs. 5%), fatigue (8% vs. 10%), increased sweating (4% vs. 8%), and increased appetite (3% vs. 6%) for Exemestane tablets and megestrol acetate, respectively. Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Adjuvant Therapy The data described below reflect exposure to Exemestane tablets in 2325 postmenopausal women with early breast cancer. Exemestane tablets tolerability in postmenopausal women with early breast cancer was evaluated in two well-controlled trials: the IES study and the 027 study (a randomized, placebo-controlled, double-blind, parallel group study specifically designed to assess the effects of Exemestane on bone metabolism, hormones, lipids, and coagulation factors over 2 years of treatment). The median duration of adjuvant treatment was 27.4 months and 27.3 months for patients receiving Exemestane tablets or tamoxifen, respectively, within the IES study and 23.9 months for patients receiving Exemestane tablets or placebo within the 027 study. Median duration of observation after randomization for Exemestane tablets was 34.5 months and for tamoxifen was 34.6 months. Median duration of observation was 30 months for both groups in the 027 study. Certain adverse reactions, which were expected based on the known pharmacological properties and side effect profiles of test drugs, were actively sought through a positive checklist. Signs and symptoms were graded for severity using CTC in both studies. Abridged from the full prescribing information.
