Arsenic TrioxideThird Party Manufacturing in India

Arsenic Trioxide works through multiple pathways to induce cancer cell death, particularly in promyelocytic leukemia cells. Its primary mechanism involves binding directly to the promyelocytic leukemia (PML) protein, which triggers the degradation of the PML-retinoic acid receptor alpha (PML-RARα) fusion protein. This fusion protein is the primary driver of acute promyelocytic leukemia (APL), blocking cell differentiation and causing the accumulation of immature white blood cells. By destroying this protein, arsenic trioxide allows leukemia cells to resume normal maturation and differentiation.

At the cellular level, arsenic trioxide also induces programmed cell death (apoptosis) by causing the loss of mitochondrial membrane potential and activating caspase enzymes. It generates reactive oxygen species (ROS), leading to oxidative stress and DNA damage within malignant cells, while inhibiting angiogenesis to cut off blood supply to tumors. Delivered as an intravenous injection, it provides targeted cytotoxic action to achieve molecular remission in patients with relapsed or refractory leukemia.

Arsenic Trioxide third party manufacturing in India delivers high-quality, sterile oncology injectables to support cancer care programs internationally.

Therapeutic Uses

Arsenic Trioxide injection is prescribed for the treatment of:

• Acute Promyelocytic Leukemia (APL): Indicated for the induction of remission and consolidation in patients with APL who are refractory to, or have relapsed from, retinoid and anthracycline therapy.
• Myelodysplastic Syndromes (MDS): Evaluated in clinical trials for patients with high-risk MDS who have limited treatment options.
• Solid Tumors: Explored in combination regimens for advanced malignancies, including hepatic and cervical cancers, to enhance chemotherapy sensitivity.

Why Choose a Leading Arsenic Trioxide Manufacturer

The production of Arsenic Trioxide requires specialized containment facilities due to the toxic nature of the active pharmaceutical ingredient (API). Sourcing from a WHO-GMP certified manufacturer in India guarantees that the product is manufactured in dedicated, high-containment suites that prevent cross-contamination and protect operators. Our partner facilities utilize advanced aseptic filling, automated weight checks, and rigorous quality control to deliver sterile injectables that meet international pharmacopoeial standards.
