Tamoxifen

Product Overview

Tamoxilon is a pharmaceutical formulation containing Tamoxifen as its active component. As a selective estrogen receptor modulator (SERM), it is principally employed in the management and prophylaxis of breast cancer. The medication exerts its therapeutic effect by antagonizing estrogen activity in breast tissue, thereby suppressing the proliferation of estrogen-dependent tumors. Marketed in oral tablet form, Tamoxilon is indicated for both early-stage and metastatic breast cancer, as well as for decreasing recurrence risk in post-surgical or post-radiation patients.

Clinical Applications

This medication is prescribed for multiple breast cancer indications, including hormone receptor-positive malignancies and ductal carcinoma in situ (DCIS). It serves as an adjuvant treatment post-surgery or radiation therapy to mitigate recurrence probability. Furthermore, Tamoxilon may be administered as prophylactic therapy for high-risk populations, such as individuals with familial breast cancer history or specific genetic predispositions.

Administration Guidelines

The oral tablets are typically administered once or twice daily, with food intake being optional. Dosage regimens and treatment duration are individualized based on disease characteristics, therapeutic response, and concomitant medications. Strict adherence to prescribing instructions is crucial for optimal efficacy and safety. Tablets should be swallowed intact with water; crushing or chewing is contraindicated.

Mechanism of Action

Tamoxifen citrate, the active pharmaceutical ingredient, functions as a competitive estrogen receptor antagonist in mammary tissue. By occupying estrogen binding sites on neoplastic cells, it disrupts estrogen-mediated signaling cascades that promote carcinogenesis. This receptor blockade results in inhibition of malignant cell proliferation and tumor regression, while simultaneously preventing de novo tumor formation.

Dosage Protocol

Therapeutic dosing is stratified according to disease stage, patient health status, and treatment response. Initiation typically involves dose titration from lower to higher concentrations. Treatment duration spans months to years based on clinical indications. Regular therapeutic monitoring through clinical follow-ups is essential throughout the treatment course.

Therapeutic Advantages

Tamoxilon demonstrates significant clinical benefits in breast cancer management, including reduced recurrence rates and improved survival outcomes, particularly in estrogen receptor-positive neoplasms. The medication may induce tumor size reduction, enhancing surgical resectability. Its favorable safety profile permits long-term administration in most patients.

Adverse Effects

Common adverse reactions include vasomotor symptoms (hot flashes), genitourinary manifestations (vaginal dryness, menstrual irregularities), gastrointestinal disturbances (nausea), asthenia, and affective disorders. Serious potential complications encompass thromboembolic events, cerebrovascular accidents, and endometrial malignancies. Persistent or severe symptoms warrant immediate medical attention.

Precautions

Enhanced vigilance is required for patients with predispositions to thromboembolism, cerebrovascular disease, or uterine cancer, particularly postmenopausal women. Absolute contraindications include pregnancy due to teratogenic risks. Women of reproductive potential must employ reliable contraception during therapy.

Storage Conditions

Maintain at controlled room temperature in a dry environment, protected from thermal extremes. Secure storage away from pediatric and pet access is mandatory. Proper disposal methods should be followed for expired or unused medication in accordance with regional pharmaceutical waste regulations.
