Exemestaz Tab

Tablets for oral administration contain 25 mg of exemestane, an irreversible, steroidal aromatase inactivator. Exemestane is chemically described as 6-methylenandrosta-1,4-diene-3,17-dione. Its molecular formula is C₂₀H₂₄O₂ and its structural formula is as follows:

The active ingredient is a white to slightly yellow crystalline powder with a molecular weight of 296.41. Exemestane is freely soluble in N, N-dimethylformamide, soluble in methanol, and practically insoluble in water.

Each Tablet contains the following inactive ingredients: mannitol, crospovidone, polysorbate 80, hypromellose, colloidal silicon dioxide, microcrystalline cellulose, sodium starch glycolate, magnesium stearate, simethicone, polyethylene glycol 6000, sucrose, magnesium carbonate, titanium dioxide, methylparaben, and polyvinyl alcohol.

Adjuvant Treatment Of Postmenopausal Women

AROMASIN is 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 AROMASIN for completion of a total of five consecutive years of adjuvant hormonal therapy

Advanced Breast Cancer In Postmenopausal Women

AROMASIN is indicated for the treatment of advanced breast cancer in postmenopausal women whose disease has progressed following tamoxifen therapy

Usage-:

Exemestane is used to treat early and advanced breast cancer in women who have already stopped menstruating (postmenopausal). It is usually used in women who have already received a cancer medication called tamoxifen. Many breast cancer tumors grow in response to estrogen.

Exemestane is also sometimes used to treat a certain type of breast cancer in women who not yet experienced menopause. Talk to your doctor about the risks of using this medication for your condition.

Aromatase inhibitors and inactivators are playing an increasing greater role in breast cancer treatment. Exemestane, a highly specific, steroidal aromatase inactivator, is the newest agent in this class. The drug is highly specific, and inhibits the in vivo conversion of androstenedione to oestrone (aromatization) by a mean of 97.9%. Exemestane has shown good efficacy and tolerability in multiple clinical trials among patients with metastatic breast cancer who have failed one or more previous hormonal therapies. Exemestane 25 mg/day slows disease progression and reduces tumour-related signs and symptoms and the drug exhibits a partial lack of cross-resistance with the non-steroidal aromatase inhibitors. Response rates to exemestane of 14% to 29% were observed including patients with visceral metastases, who have historically proven difficult to treat. In a large phase III trial, exemestane was found to be superior to megestrol acetate with respect to time to progression and overall survival. In addition, exemestane is currently under investigation as first-line therapy in metastatic disease and in sequence with tamoxifen in the adjuvant setting. Adverse events include low-grade hot flashes, nausea, and fatigue–mostly of mild to moderate intensity–and treatment-related discontinuations are rare. In conclusion, exemestane represents a novel and interesting drug for the treatment of advanced breast cancer, with exciting prospects for use in adjuvant therapy and, potentially, breast cancer prevention.

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 (027). Concomitant use of bisphosphonates, vitamin D supplementation, and calcium was not allowed.

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 Agen

should not be coadministered with systemic estrogen-containing agents as these could interfere with its pharmacologic action.
