Description

Tamoxifen Citrate (Nolvadex) 20mg – ZPHC (100 Tablets)

Product Overview

Tamoxifen Citrate, commonly recognized under the brand name Nolvadex, is a selective estrogen receptor modulator (SERM) available in 20 mg film-coated tablets from ZPHC . Each pack contains 100 tablets, providing a complete course for post-cycle therapy or ongoing treatment protocols. Tamoxifen functions as a competitive antagonist of estrogen receptors, particularly in breast tissue, making it a core agent for both post-cycle therapy (PCT) and estrogen-control research .

Mechanism of Action

Tamoxifen Citrate works by binding to estrogen receptors and blocking the effects of estrogen in target tissues. As a SERM, it demonstrates tissue-specific activity: antagonistic effects in breast tissue while exhibiting partial agonist activity in other tissues such as bone and liver . In the context of post-cycle therapy, tamoxifen stimulates the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) by blocking estrogen’s negative feedback at the hypothalamic-pituitary level, which in turn triggers endogenous testosterone production in the testes . This mechanism makes it an essential component of recovery protocols following anabolic steroid cycles.

Product Features

• Presentation: 100 film-coated tablets per pack

• Quality Control: Minimum 99% API purity verified by HPLC; manufactured under GMP standards

• Authenticity: Tamper-evident cap with scratch-code verification

• Formulation: Tamoxifen Citrate equivalent to 20 mg tamoxifen per tablet 

Key Applications

Post-Cycle Therapy (PCT)

Tamoxifen is widely utilized as a foundational compound in PCT protocols to restore natural testosterone production and prevent estrogenic side effects . Standard PCT protocols typically follow a tapering schedule:

• 40 mg per day for 7-14 days

• Followed by 20 mg per day for 14-28 days

• Total course duration generally 4-6 weeks

Estrogen Management

For individuals running aromatizable compounds, tamoxifen serves as a frontline defense against gynecomastia by competitively inhibiting estrogen receptors in breast tissue. It can be combined with aromatase inhibitors when needed for comprehensive estrogen control.

Breast Cancer Research Applications

Tamoxifen is extensively used in medical research settings for studies involving estrogen-dependent breast cancer cell lines . As a cytostatic agent, it prevents pre-cancerous cells from dividing without causing cell death, making it valuable for understanding cancer biology and therapeutic interventions .

Drug Interactions and Cautions

Important Precautions

• Tamoxifen should be avoided during pregnancy and breastfeeding due to potential harm to the developing fetus 

• Concurrent use of potent CYP2D6 inhibitors (including paroxetine, fluoxetine, quinidine, and bupropion) should be avoided as they may reduce concentrations of active metabolites 

• Caution is advised in individuals with a history of thromboembolic events, stroke, or pulmonary embolism 

• The risk of endometrial cancer and uterine sarcoma has been reported in association with tamoxifen treatment; any abnormal gynecological symptoms, particularly vaginal bleeding, should be promptly investigated 

Potential Side Effects

Common side effects include hot flashes, nausea, fatigue, and headaches . In men, tamoxifen therapy is generally well-tolerated, with less than 5% of patients discontinuing treatment due to adverse effects . Serious but rare events include thromboembolic events, visual disturbances, and endometrial changes .

Quality Assurance

This ZPHC product features pharmaceutical-grade quality control, with each batch tested for ≥99% API purity using high-performance liquid chromatography (HPLC). The tablets are manufactured under Good Manufacturing Practice (GMP) standards to ensure consistency, potency, and reliability.

Top 10 Frequently Asked Questions

1. What is the recommended dosage for post-cycle therapy?

The typical PCT protocol begins with 40 mg daily for 7-14 days, followed by 20 mg daily for 14-28 days, totaling 4-6 weeks of therapy. Dosage should be individualized based on cycle specifics and individual response .

2. What is the difference between Tamoxifen Citrate and Tamoxifen base?

Tamoxifen Citrate tablets contain 30.4 mg of Tamoxifen Citrate equivalent to 20 mg of Tamoxifen base . The citrate is the salt form used in pharmaceutical preparations for improved stability and bioavailability.

3. Can Tamoxifen be used during a steroid cycle?

Yes, tamoxifen can be used during a cycle as a preventative measure against gynecomastia at lower doses (10-20 mg daily). It effectively blocks estrogen receptors in breast tissue without significantly affecting systemic estrogen levels .

4. How quickly does Tamoxifen work for gynecomastia?

Tamoxifen begins binding to estrogen receptors within hours of administration. However, visible reduction in gynecomastia symptoms may take several days to weeks, depending on the severity of the condition .

5. Is Tamoxifen effective for male infertility?

Research indicates that tamoxifen can enhance GnRH secretion at the hypothalamus level, subsequently increasing pituitary LH and FSH secretion, which stimulates spermatogenesis. This makes it a viable option for treating male infertility, although its use remains off-label .

6. What medications should not be taken with Tamoxifen?

Potent CYP2D6 inhibitors including paroxetine, fluoxetine, quinidine, cinacalcet, and bupropion should be avoided when possible. Additionally, coumarin-type anticoagulants may require dose adjustment due to increased anticoagulant effects .

7. What are the signs of Tamoxifen-related endometrial changes?

Symptoms requiring immediate investigation include abnormal vaginal bleeding or discharge (particularly if bloody, brown, or rusty), changes in menstrual bleeding patterns, and pelvic pain or pressure .

8. Can Tamoxifen cause vision problems?

Tamoxifen has been associated with cataracts, retinopathy, and other visual disturbances. Patients should undergo ophthalmological examination before initiating therapy and report any visual changes promptly .

9. What is the half-life of Tamoxifen?

Tamoxifen has a prolonged elimination half-life of approximately 5-7 days, with active metabolites persisting for several weeks. This long half-life supports once-daily dosing and gradual tapering during PCT .

10. Is pregnancy a contraindication for Tamoxifen?

Tamoxifen is absolutely contraindicated during pregnancy. Women should not become pregnant during treatment and for at least 2 months following cessation of therapy. Non-hormonal contraceptive methods are recommended during this period .
