Busulfan
Overview
What is Busulfan?
Busulfan, USP is a bifunctional alkylating agent known chemically as 1,4-butanediol, dimethanesulfonate. Busulfan injection is intended for intravenous administration. It is supplied as a clear, colorless, sterile, solution in 10 mL single-dose vials. Each vial of busulfan injection contains 60 mg (6 mg/mL) of busulfan USP, the active ingredient, a white crystalline powder with a molecular formula of CHSOO(CH)OSOCH and a molecular weight of 246.30 g/mole. Busulfan, USP has the following chemical structure:
Busulfan, USP is dissolved in N,N-dimethylacetamide (DMA), 3.3 mL and Polyethylene Glycol 400, 6.7 mL. The solubility of busulfan, USP in water is very slightly soluble in water and the pH of busulfan injection diluted to approximately 0.5 mg per mL busulfan in 0.9% Sodium Chloride Injection, USP or 5% Dextrose Injection, USP as recommended for infusion reflects the pH of the diluent used and ranges from 3.4 to 3.9.

What are the available doses of Busulfan?
60 mg per 10 mL (6 mg per mL) single-dose vial.
What should I talk to my health care provider before I take Busulfan?
How should I use Busulfan?
Busulfan injection is indicated for use in combination with cyclophosphamide as a conditioning regimen prior to allogeneic hematopoietic progenitor cell transplantation for chronic myelogenous leukemia.

What should I look out for while using Busulfan?
Busulfan injection is contraindicated in patients with a history of hypersensitivity to any of its components.
Busulfan injection causes severe and prolonged myelosuppression at the recommended dosage. Hematopoietic progenitor cell transplantation is required to prevent potentially fatal complications of the prolonged myelosuppression
What might happen if I take too much Busulfan?
There is no known antidote to busulfan other than hematopoietic progenitor cell transplantation. In the absence of hematopoietic progenitor cell transplantation, the recommended dosage for busulfan would constitute an overdose of busulfan. The principal toxic effect is profound bone marrow hypoplasia/aplasia and pancytopenia, but the central nervous system, liver, lungs, and gastrointestinal tract may be affected. Monitor hematologic status closely and institute vigorous supportive measures as medically indicated. Survival after a single 140 mg dose of Myleran Tablets in an 18 kg, 4-year old child has been reported. Inadvertent administration of a greater than normal dose of oral busulfan (2.1 mg per kg; total dose of 23.3 mg per kg) occurred in a 2-year old child prior to a scheduled bone marrow transplant without sequelae. An acute dose of 2.4 g was fatal in a 10-year old boy. There is one report that busulfan is dialyzable, thus dialysis should be considered in the case of overdose.

Clinical Information
Chemical Structure
No Image foundClinical Pharmacology
Busulfan is a bifunctional alkylating agent in which two labile methanesulfonate groups are attached to opposite ends of a four-carbon alkyl chain. In aqueous media, busulfan hydrolyzes to release the methanesulfonate groups. This produces reactive carbonium ions that can alkylate DNA. DNA damage is thought to be responsible for much of the cytotoxicity of busulfan.
Non-Clinical Toxicology
Busulfan injection is contraindicated in patients with a history of hypersensitivity to any of its components.Busulfan injection causes severe and prolonged myelosuppression at the recommended dosage. Hematopoietic progenitor cell transplantation is required to prevent potentially fatal complications of the prolonged myelosuppression
Increased nephrotoxicity has been reported following concomitant administration of cephalosporins and aminoglycoside antibiotics.
The most frequent serious consequence of treatment with busulfan at the recommended dose and schedule is prolonged myelosuppression, occurring in all patients (100%). Severe granulocytopenia, thrombocytopenia, anemia, or any combination thereof may develop. Hematopoietic progenitor cell transplantation is required to prevent potentially fatal complications of the prolonged myelosuppression. Monitor complete blood counts, including white blood cell differentials, and quantitative platelet counts daily during treatment and until engraftment is demonstratedAbsolute neutrophil counts dropped below 0.5x10/L at a median of 4 days post-transplant in 100% of patients treated in the busulfan clinical trial. The absolute neutrophil count recovered at a median of 13 days following allogeneic transplantation when prophylactic G-CSF was used in the majority of patients. Thrombocytopenia (less than 25,000/mmor requiring platelet transfusion) occurred at a median of 5 to 6 days in 98% of patients. Anemia (hemoglobin less than 8.0 g/dL) occurred in 69% of patients. Use antibiotic therapy and platelet and red blood cell support when medically indicated.
