Kessar

Tamoxifen citrate, the active ingredient in Kessar, is a selective estrogen receptor modulator presented as an oral tablet for oral use. It is employed in hormone therapy to treat estrogen receptor‑positive breast cancer and to reduce cancer risk in women at high risk. GNH USA supplies Kessar as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, oncology centres, pharmacies and clinics worldwide.

Tamoxifen citrate is a SERM used in the management of estrogen‑driven breast cancer and related risk scenarios. - Adjuvant breast cancer: improves disease‑free survival after surgery in estrogen receptor‑positive patients. - Metastatic breast cancer: slows disease progression in advanced hormone‑sensitive tumors. - High‑risk women: lowers the incidence of invasive breast cancer in women with a strong family or genetic predisposition.

Tamoxifen citrate may cause a range of adverse reactions that vary in frequency and severity.

Common Side Effects: - Hot flashes: transient episodes of warmth and sweating. - Nausea: mild to moderate stomach upset. - Fatigue: persistent tiredness not relieved by rest. - Vaginal discharge or dryness: changes in genital secretions. - Menstrual irregularities: altered cycle length or flow. - Weight gain: modest increase in body weight.

Serious or Rare Side Effects: - Deep vein thrombosis or pulmonary embolism: signs of clot formation. - Endometrial cancer: abnormal uterine bleeding. - Liver toxicity: jaundice or elevated liver enzymes. - Visual disturbances: blurred vision or retinal changes. - Severe allergic reaction: rash, swelling, or breathing difficulty.

Before initiating tamoxifen citrate therapy, consider the following safety measures. - Pregnancy testing: confirm non‑pregnant status before starting treatment. - Thromboembolic risk: assess personal or family history of clotting disorders. - Liver function: obtain baseline liver enzyme tests and monitor periodically. - Ocular health: schedule regular eye examinations for patients with visual symptoms. - Drug interactions: review concomitant medications for potential CYP2D6 inhibitors. - Store at ambient temperature: keep below 25 °C in the original container, protect from moisture and direct sunlight.

Tamoxifen citrate can interact with several medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid): - Strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine): may reduce tamoxifen activation. - Anticoagulants (e.g., warfarin): increased risk of bleeding. - Hormonal contraceptives: may diminish contraceptive efficacy.

Moderate Interactions (Monitor Closely): - SSRIs with weak CYP2D6 inhibition (e.g., sertraline): monitor therapeutic response. - Aromatase inhibitors: overlapping endocrine effects require clinical judgment. - Herbal supplements (e.g., St. John’s wort): may induce metabolism and lower drug levels.
