Product Description
Introduction
ANTREOL-1 ANASTROZOLE Tablets IP 1mg is a highly effective medication designed to manage and treat hormone receptor-positive breast cancer in postmenopausal women. This medication belongs to the class of drugs known as aromatase inhibitors and is manufactured by Knoll Healthcare, a trusted name in pharmaceuticals.
Active Ingredient
Each tablet contains 1 mg of Anastrozole, an aromatase inhibitor that significantly reduces the amount of estrogen in the body. By lowering estrogen levels, Anastrozole helps slow or reverse the growth of estrogen-dependent breast cancer.
Indications
ANTREOL-1 is primarily indicated for:
- Postmenopausal Women: Treatment of hormone receptor-positive early breast cancer.
- Advanced Breast Cancer: First-line treatment in postmenopausal women with hormone receptor-positive or hormone receptor unknown locally advanced or metastatic breast cancer.
- Adjuvant Treatment: As an adjuvant treatment for postmenopausal women with hormone receptor-positive breast cancer to prevent recurrence.
Dosage and Administration
- Recommended Dose: One tablet (1 mg) taken orally once daily.
- Administration: The tablet should be swallowed whole with water, with or without food, at the same time each day to maintain an even level of the medication in your body.
- Duration: The duration of treatment will be determined by the healthcare provider based on the individual’s response and clinical condition.
Mechanism of Action
Anastrozole works by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogens. By blocking this conversion, Anastrozole effectively reduces estrogen levels, thereby slowing the growth of estrogen-dependent breast cancer cells.
