Arsenic Trioxide

Arsenic Trioxide is an anti-cancer medication primarily used in the treatment of acute promyelocytic leukemia (APL), a subtype of acute myeloid leukemia. It is a chemotherapeutic agent that induces cancer cell death and helps restore normal cell differentiation.

Uses

• Treatment of Acute Promyelocytic Leukemia (APL)
• Used in combination with other chemotherapy agents
• Effective in cases resistant to other treatments

How it works

Arsenic Trioxide works by causing structural changes and degradation of the PML-RARα fusion protein found in APL cells. This leads to apoptosis (programmed cell death) and differentiation of the abnormal promyelocytes, restoring healthy blood cell formation.

Benefits

• Targets the underlying genetic abnormality in APL
• Effective in relapsed or refractory APL cases
• Can lead to complete remission when used appropriately

How to take

Arsenic Trioxide is administered intravenously by a healthcare provider. The dosage is based on body weight and treatment response. It requires careful monitoring during administration to manage potential side effects.

Type of Dosage Available

• Intravenous infusion solution

Side effects

• QT prolongation (heart rhythm disorder)
• Nausea and vomiting
• Fatigue
• Electrolyte imbalance
• Headache
• Fever
• Differentiation syndrome (potentially life-threatening)

Safety advice

• Requires ECG monitoring due to risk of QT prolongation
• Use with caution in patients with heart disease or electrolyte imbalance
• Not recommended during pregnancy or breastfeeding unless necessary
• Regular monitoring of blood counts and liver/kidney function is essential
