Summary
Vinca alkaloids, such as vincristine and vinblastine are chemotherapeutic drugs that function by blocking microtubule formation. This prevents formation of the mitotic spindle and inhibits cell replication. Patients taking vincristine are at risk for developing neurotoxicity, and a less specific side effect seen is bone marrow suppression.
