Vincristine Sulphate Injection

Category: Chemotherapy / Antineoplastic agent
Form: Injectable solution for intravenous (IV) use

Uses:

• Treatment of various cancers, including:

  • Acute lymphoblastic leukemia (ALL)

  • Hodgkin’s lymphoma

  • Non-Hodgkin’s lymphoma

  • Neuroblastoma

  • Certain other solid tumors depending on treatment protocol

• Often used as part of combination chemotherapy regimens.

Mechanism of Action:

• Vincristine is a vinca alkaloid.

• Binds to tubulin, preventing microtubule assembly.

• Disrupts mitotic spindle formation during metaphase, leading to cell cycle arrest.

• Causes apoptosis (programmed cell death) in rapidly dividing cancer cells.

Administration:

• Administered intravenously, typically as a slow injection or infusion to prevent tissue damage.

• Dosage depends on type of cancer, patient weight or body surface area, and treatment protocol.

• Usually given in cycles, with rest periods to allow recovery of healthy cells.

Side Effects:

• Neurological: peripheral neuropathy, numbness, tingling, constipation, jaw pain (most prominent side effect).

• Hematologic: mild leukopenia; less myelosuppression compared to other vinca alkaloids.

• Gastrointestinal: nausea, vomiting, constipation.

• Other: hair loss, fatigue, injection site reactions.

Precautions:

• Monitor nerve function and gastrointestinal health regularly due to neurotoxicity.

• Avoid extravasation during IV administration as it can cause severe tissue damage.

• Dose adjustment required in patients with liver impairment.

• Pregnancy and breastfeeding: contraindicated due to teratogenic potential.

• Careful monitoring in combination chemotherapy to prevent additive toxicities.

Summary:
Vincristine Sulphate Injection is a chemotherapy drug that inhibits microtubule assembly, causing cell cycle arrest and apoptosis in rapidly dividing cancer cells. It is used in the treatment of leukemia, lymphomas, neuroblastoma, and other malignancies. Administered intravenously in cycles, it is associated primarily with neurotoxicity, constipation, and mild hematologic effects, requiring careful monitoring and supportive care.
