Mode of action

Tubulin is a structural protein which polymerises to form microtubules. The cell cytoskeleton and mitotic spindle, amongst other things, are made of microtubules. Vincristine binds to tubulin dimers, inhibiting assembly of microtubule structures. Disruption of the microtubules arrests mitosis in metaphase. The vinca alkaloids therefore affect all rapidly dividing cell types including cancer cells, but also intestinal epithelium and bone marrow. Tubulin is the protein which makes up microtubules. ...

Vincristine, injected intravenously only, is used in various types of chemotherapy regimens. Its main uses are in non-Hodgkin's lymphoma as part of the chemotherapy regimen CHOP, Hodgkin's lymphoma as part of MOPP or COPP, or the less popular Stanford V chemotherapy regimen, and in acute lymphoblastic leukemia. It is occasionally used as an immunosuppressant, e.g. in thrombotic thrombocytopenic purpura (TTP).

Accidental injection of vinca alkaloids into the spinal canal (intrathecal administration) is highly dangerous, with a mortality rate approaching 100%. The medical literature documents cases of ascending paralysis due to massive encephalopathy and spinal nerve demyelination, accompanied by intractable pain, almost uniformly leading to death; a handful of survivors were left with devastating neurological damage with no hope of recovery. Rescue treatments consist of washout of the cerebrospinal fluid and administration of protective medications.[1] Intrathecal: Delivered into the spinal canal (intrathecal space surrounding the spinal cord), as in a spinal anaesthesia. ...

Side effects

The main side-effects of vincristine are peripheral neuropathy, hyponatremia, and constipation. Peripheral neuropathy is the term for damage to nerves of the peripheral nervous system, which may be caused either by diseases of the nerve or from the side-effects of systemic illness. ... The electrolyte disturbance hyponatremia or hyponatraemia exists in humans when the sodium level in the plasma falls below 135 mmol/l. ... Constipation or irregularity, is a condition of the digestive system where a person (or animal) experiences hard feces that are difficult to egest; it may be extremely painful, and in severe cases (fecal impaction) lead to symptoms of bowel obstruction. ...

Peripheral neuropathy can be severe, hence reason to avoid, reduce, or stop the use of vincristine. One of the first symptoms of peripheral neuropathy is foot drop: a person with a family history of foot drop and/or Charcot-Marie-Tooth disease (CMT) may benefit from genetic testing for CMT before taking vincristine.[2] An editor has expressed a concern that the subject of the article does not satisfy the notability guideline or one of the following guidelines for inclusion on Wikipedia: Biographies, Books, Companies, Fiction, Music, Neologisms, Numbers, Web content, or several proposals for new guidelines. ... Charcot-Marie-Tooth disease (CMT), known also as Hereditary Motor and Sensory Neuropathy (HMSN) or Peroneal Muscular Atrophy, is a heterogeneous inherited disorder of nerves (neuropathy) that is characterized by loss of muscle tissue and touch sensation, predominantly in the feet and legs but also in the hands and arms...


Having been used as a folk remedy for centuries, studies in the 1950s revealed that C. roseus contained 70 alkaloids, many of which are biologically active. While initial studies for its use in diabetes mellitus were disappointing, the discovery that it caused myelosuppression (decreased activity of the bone marrow) led to its study in mice with leukemia, whose lifespan was prolonged by the use of a vinca preparation. Treatment of the ground plant with Skelly-B defatting agent and an acid benzene extract led to a fraction termed "fraction A". This fraction was further treated with aluminium oxide, chromatography, trichloromethane, benz-dichloromethane and separation by pH to yield vincristine.[3] Binomial name (L.)

Vincristine sulfate is the salt of an alkaloid obtained from a flowering herb, the Madagascar periwinkle plant (Catharanthus roseus, formerly classified as Vinca rosea Linn, which caused it to be called a vinca alkaloid) (Greuter et al., 1999).
Vincristine inhibits microtubule formation in the mitotic spindle, resulting in the arrest of dividing cells at the metaphase stage and, because of this action, sometimes is referred to as an antimicrotubule agent.
Dispensing vincristine in small-volume infusion bags or diluting the dose to at least 10 ml to help differentiate it from intrathecal drugs, for which such a large volume is not given, may help to reduce the potential for inadvertent intrathecal vincristine administration.
