This is a fluorinated nucleotide analogue of the antiviral vidarabine which acts as a purine antagonist antimetabolite. Indications: Treatment of advanced B-cell chronic lymphocytic leukaemia for patients who either have failed or are intolerant of, first-line chemotherapy. Cautions: dosage should be reduced in renal impairment and fludarabine should not be given if creatinine clearance is less than 30ml/minute. It should also be avoided in patients with decompensated haemolytic anaemia. Contra-indications: Haemolytic anaemia; pregnancy & breast feeding. Side effect: Myelosuppression which can be severe and cumulative; immuno-suppression is also common and co- trimoxazole is often used to prevent pneumocystis infection. Immune-mediated haemolytic anaemia, thrombocytopenia, and neutropenia are less common side effects.
