PMS-BUSULFAN (BUSULFAN) INJECTION IS A POTENT CYTOTOXIC DRUG THAT
RESULTS IN PROFOUND MYELOSUPPRESSION AT THE RECOMMENDED DOSAGE. IT
SHOULD BE ADMINISTERED UNDER THE SUPERVISION OF A QUALIFIED PHYSICIAN
WHO IS EXPERIENCED IN THE USE OF CANCER CHEMOTHERAPEUTIC AGENTS AND
IN THE MANAGEMENT OF PATIENTS WITH SEVERE PANCYTOPENIA. APPROPRIATE
MANAGEMENT OF THERAPY AND COMPLICATIONS IS ONLY POSSIBLE WHEN
ADEQUATE DIAGNOSTIC AND TREATMENT FACILITIES ARE READILY AVAILABLE.
ACTIONS AND CLINICAL PHARMACOLOGY
Busulfan is a potent cytotoxic agent and a bifunctional alkylating
agent. In aqueous media, release
of the methanesulfonate group produces carbonium ions, which can
alkylate DNA, thought to be an
important biological mechanism for its cytotoxic effect.
Current literature suggests that high AUC values (>1,500 mcMol•min)
may be associated with an
increased risk of developing hepatic veno-occlusive disease and/or
seizures.

Intravenous busulfan had a more consistent pharmacokinetic profile
than oral busulfan among
patients.
Busulfan achieves concentrations in the cerebrospinal fluid
approximately equal to those in plasma.
Irreversible binding to plasma elements, primarily albumin, has been
estimated to be 32.4 ± 2.2%,
which is consistent with the reactive electrophi
