Aromatin (Anastrozole) tablet contains 1 mg of Anastrozole which is a non-steroidal aromatase inhibitor.


The growth of many cancers of the breast is stimulated or maintained by estrogens. Anastrozole significantly lowers serum estradiol concentration in postmenopausal women, thus indicated for the treatment of postmenopausal women with hormone receptor-positive or hormone receptor unknown breast cancer.


    Aromatin 1 mg Tablet: Each film-coated tablet contains Anastrozole USP 1 mg.


    Adjuvant treatment: Aromatin is indicated for adjuvant treatment of postmenopausal women with hormone receptor-positive early breast cancer.
    First-line treatment: Aromatin is indicated for the first-line treatment of postmenopausal women with hormone receptor-positive or hormone receptor unknown locally advanced or metastatic breast cancer.
    Second-line treatment: Aromatin is indicated for the treatment of advanced breast cancer in postmenopausal women with disease progression following tamoxifen therapy.

Dosage & Administration

    The dose of Aromatin is 1 mg tablet taken once daily.

    For patients with advanced breast cancer, Aromatin should be continued until tumor progression. For adjuvant treatment of early breast cancer in postmenopausal women, the recommended duration of treatment should be 5 years.

    Aromatin can be taken with or without food.


    Anastrozole is contraindicated in any patient who has shown a hypersensitivity reaction to the drug or to any of the excipients. Observed reactions include anaphylaxis, angioedema and urticaria.

Warning & Precautions

    Pregnancy: Pregnancy category X. Anastrozole can cause fetal abnormalities and risks, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.

    Nursing mothers: It is not known whether Anastrozole is excreted into human milk or not. Caution should be exercised if Anastrozole is administered to women who are breastfeeding.

    Pediatric use: The safety and efficacy of Anastrozole has not been established in pediatric cases.

    Geriatric Use: The pharmacokinetics of Anastrozole is not affected by age. In case of efficacy, Anastrozole gives better result in women with > 65 years old.

    Premenopausal women: Anastrozole offers no clinical benefit to premenopausal women with breast cancer.

    Ischemic cardiovascular events: Caution should be exercised if Anastrozole is administered to women with pre-existing ischemic heart disease.

    Renal impairment: The renal impairment does not influence the total body clearance. Dosage adjustment in patients with renal impairment is not necessary.

    Hepatic impairment: Dosage adjustment is also not necessary in patients with stable hepatic cirrhosis. Anastrozole has not been studied in patients with severe hepatic impairment.

Side effects

    Common adverse reactions: Common adverse reactions (occurring with an incidence of >10%) in women taking Anastrozole includes hot flashes, asthenia, arthritis, pain, arthralgia, hypertension, depression, nausea and vomiting, rash, osteoporosis, fractures, back pain, insomnia, headache, bone pain, peripheral edema, increased cough, dyspnea, pharyngitis and lymphedema. Dermatologic: Skin reactions such as lesions, ulcers, or blisters (less than 1 in 10,000 patients). Allergic effects: Allergic reactions with swelling of the face, lips, tongue and/or throat. This may cause difficulty in swallowing and/or breathing (less than 1 in 10,000 patients). Hematologic: Changes in blood tests of the liver function, including inflammation of the liver (less than 1 in 10,000 patients). Bone effects: Clinical trial showed that patients receiving Anastrozole had a mean decrease in both lumbar spine and total hip bone mineral density (BMD). Cholesterol: Anastrozole may cause an increase in serum cholesterol level.

Drug interaction

    Tamoxifen: Co-administration of Anastrozole and tamoxifen in breast cancer patients reduced Anastrozole plasma concentration by 27%. Tamoxifen should not be administered with Anastrozole. Estrogen: Estrogen-containing therapies should not be used with Anastrozole. Warfarin: Anastrozole doesn't alter the activity of both R- and S-warfarin. Cytochrome P450 enzyme: The inhibition of cytochrome P450 enzymes by Anastrozole doesn't affect the action of other drugs.
