Arsenox 1mg Injection

About

Arsenox 1mg Injection contains Arsenic Trioxide, a potent antineoplastic agent primarily used in the treatment of acute promyelocytic leukemia (APL). Its mechanism of action involves inducing differentiation and apoptosis in APL cells, which are characterized by the PML-RARα fusion protein. Arsenic Trioxide causes degradation of this fusion protein, leading to the maturation of promyelocytes into mature granulocytes and ultimately inducing cell death in leukemic cells. This targeted approach helps to clear the bone marrow of cancerous cells and restore normal hematopoiesis.

The medication is administered intravenously under strict medical supervision, often as part of an induction and consolidation regimen for APL. Its efficacy is well-established in both newly diagnosed and relapsed/refractory APL cases. Due to its specific mechanism and potential for serious side effects, including cardiac toxicity, patients require close monitoring, particularly for QT interval prolongation and electrolyte imbalances, throughout the treatment course to ensure safety and optimize therapeutic outcomes.

Uses

• Treatment of newly diagnosed low-risk acute promyelocytic leukemia (APL).
• Management of relapsed or refractory acute promyelocytic leukemia (APL).
• Induces differentiation and apoptosis in APL cells.
• Used in combination with all-trans retinoic acid (ATRA) for APL.

Directions For Use

Administered intravenously by a healthcare professional. Dosage and infusion rate are carefully determined by the oncologist.

Benefits

• Highly effective in inducing remission in APL.
• Offers a targeted therapy for APL with specific genetic markers.
• Can be used in both frontline and relapsed settings.
• Reduces the burden of leukemic cells in the bone marrow.
• Improves overall survival rates in APL patients.
• Provides a non-chemotherapeutic option for APL.

Side Effects

• Fatigue and weakness
• Nausea and vomiting
• Diarrhea or constipation
• Fever
• Headache
• Peripheral neuropathy
• QT interval prolongation (cardiac risk)
• Electrolyte disturbances (e.g., hypokalemia, hypomagnesemia)
• Liver enzyme elevations
• Skin rash
• Cough or shortness of breath
• Differentiation syndrome (a serious complication)

Safety Measures

• Alcohol - Avoid alcohol during treatment as it can exacerbate liver toxicity and other side effects.
• Pregnancy - Arsenox is highly teratogenic and contraindicated in pregnancy. Effective contraception is essential for both male and female patients.
• Breastfeeding - Breastfeeding is contraindicated during Arsenox treatment due to the potential for serious adverse effects on the infant.
• Liver - Use with caution in patients with hepatic impairment. Liver function should be monitored frequently, and dose adjustments may be necessary.
• Kidney - Patients with renal impairment require careful monitoring and potential dose adjustments due to the risk of drug accumulation and toxicity.
• Lung - Monitor for signs of differentiation syndrome, which can include respiratory distress. Also, monitor for other pulmonary toxicities.
