About

Vinblastine is a prominent vinca alkaloid, a class of antineoplastic agents derived from the Catharanthus roseus plant, commonly known as the Madagascar periwinkle. This chemotherapy drug exerts its cytotoxic effects by specifically targeting and disrupting microtubule formation, which is a critical process for cell division and maintaining cellular structure. By inhibiting the polymerization of tubulin into microtubules, vinblastine effectively arrests cancer cells in the metaphase stage of mitosis, preventing them from completing cell division and ultimately leading to programmed cell death (apoptosis). It is a vital component in the treatment protocols for various hematological malignancies and solid tumors, including Hodgkin's lymphoma, non-Hodgkin's lymphoma, and testicular cancer. Its efficacy is due to its selective action on rapidly dividing cells, making it a powerful tool in multi-drug chemotherapy regimens.

Uses

Treatment of Hodgkin's lymphoma.
Management of non-Hodgkin's lymphoma.

Safety Measures

Alcohol - Avoid alcohol due to potential for increased gastrointestinal upset and liver strain, especially during chemotherapy.
Pregnancy - Contraindicated due to severe teratogenic effects and fetal harm. Effective contraception is essential during treatment.
Breastfeeding - Contraindicated. Vinblastine is likely excreted in breast milk and can cause serious adverse effects in the infant.
Liver - Use with extreme caution and reduce dosage in patients with significant liver impairment due to altered metabolism and increased toxicity.
Kidney - Use with caution in patients with severe kidney impairment; monitor renal function closely.
Lung - Rare but serious pulmonary toxicity (e.g., bronchospasm, shortness of breath) can occur, especially in combination with mitomycin.
