Documented Uses

• ... in the treatment of acute leukemia in children /Vincristine sulfate USP/
• Therapeutic Category: Antineoplastic
• Treatment of acute lymphocytic leukemia (ALL), Hodgkin lymphoma, non-Hodgkin lymphomas, Wilms' tumor, neuroblastoma, rhabdomyosarcoma. Liposomal vincristine is indicated for the treatment of relapsed Philadelphia chromosome-negative (Ph-) acute lymphoblastic leukemia (ALL).
• Vinblastine and vincristine occur in Catharanthus roseus (L). The plant contains only very small amounts of vinblastine and vincristine, and their isolation is correspondingly difficult. First the alkaloids present are separated by extraction into alkaloid tartrate soluble in benzene and alkaloid tartrates insoluble in benzene. Vinblastine and vincristine belong to the first group. They then are separated by chromatography on aluminum oxide deactivated with acetic acid.
• Isolation from Vinca rosea Linn (Catharanthus roseus G Don), Apocynaceae.
• USING SUITABLE MODIFICATIONS IN CHROMATOGRAPHIC PART OF PROCESS, VINCRISTINE SULFATE ISOLATING ALKALOID FROM EXTRACT BY USUAL PPT & SOLVENT TECHNIQUES & PURIFYING BY CHROMATOGRAPHY ON ALUMINUM OXIDE. CONVERSION TO SULFATE BY /ADDN OF SULFURIC ACID/ ... . /VINCRISTINE SULFATE/
