What Busilvex Is And What It Is Used For
Busilvex contains the substance busulfan, which belongs to a group of medicines called alkylating agents. Busilvex destroys the original bone marrow before the transplant.
Busilvex is used in adults, new-born infants, children and adolescents as a treatment prior to transplantation.
In adults Busilvex is used in combination with cyclophosphamide.
