Desferrioxamine mesilate
Indications/Uses
Monotherapy Fe chelation treatment for chronic Fe overload eg, transfusional hemosiderosis, as seen in thalassemia major, sideroblastic anemia, auto-immune hemolytic anemia & other chronic anemias; idiopathic (primary) hemochromatosis in patients in whom concomitant disorders (eg, severe anemia, cardiac disease, hypoproteinemia) preclude phlebotomy; Fe overload associated w/ porphyria cutanea tarda in patients unable to tolerate phlebotomy. Acute Fe poisoning. Chronic Al overload in patients w/ end-stage renal failure (under maintenance dialysis) w/ Al-related bone disease, dialysis encephalopathy or Al-related anemia. Diagnosis of Fe or Al overload.
Dosage/Direction for Use
Chronic Fe overload Adult & childn 20-60 mg/kg daily. Patient w/ higher serum ferritin May require up to 55 mg/kg daily, serum ferritin level between 2,000 & 3,000 ng/mL 35 mg/kg daily, serum ferritin level <2,000 ng/mL 25 mg/kg daily. Acute Fe poisoning 15 mg/kg/hr by continuous IV, reduced as soon as circumstances permit, usually after 4-6 hr, so that total IV dose does not exceed 80 mg/kg in any 24-hr period. Chronic Al overload in end-stage renal failure 5 mg/kg once wkly administered by slow IV infusion 5 hr prior to dialysis session in patient w/ post-DFO test serum Al level >300 ng/mL or during the last 60 min of dialysis session in patient w/ post-DFO test serum Al level up to 300 ng/mL. After completion of the 1st 3-mth course of treatment followed by a 4-wk wash-out period, infusion test should be performed. If 2 successive infusion tests performed at 1-mth interval yield serum Al level <50 ng/mL above baseline, further treatment is not recommended. Patient on continuous ambulatory peritoneal dialysis or continuous cyclic peritoneal dialysis 5 mg/kg once wkly prior to the final exchange of the day given IP, IM, by slow IV infusion or SC.
Contraindications
Hypersensitivity except where successful desensitization makes treatment possible.
Special Precautions
Not to be given at conc >95 mg/mL when given SC. Rapid IV infusion may lead to hypotension & shock. Discontinue immediately if visual or auditory disturbances occur. Acute resp distress syndrome following excessively high IV dose. Increased susceptibility to infections eg, w/ Yersinia enterolitica & Yersinia pseudotuberculosis; rare cases of mucormycosis. May exacerbate neurological dysfunction (convulsion) (in high doses), precipitate onset of dialysis dementia & result in hypocalcemia & aggravation of hyperparathyroidism in patients treated for chronic Al overload. Perform ophth & audiological tests prior to treatment & at regular intervals (every 3 mth) thereafter. May cause reddish brown discoloration of urine. Not to be given w/ vit C supplements in patients w/ cardiac failure. Patients experiencing dizziness or other central nervous disturbances, or vision or hearing impairment should refrain from driving vehicle or operating machines. Hepatic & severe renal impairment. Pregnancy & lactation. Monitor ped patients for body wt & longitudinal growth every 3 mth. Elderly ≥65 yr.
Adverse Reactions
Arthralgia, myalgia; inj site reaction, pain, swelling, extravasation, erythema, pruritus & scab. Headache; nausea; urticaria; growth retardation, bone disorder, metaphyseal dysplasia (in high doses & in childn); pyrexia.
Drug Interactions
May lead to temporary impairment of consciousness w/ prochlorperazine. Impairment of cardiac function w/ high doses of vit C. May distort gallium-67-imaging results.
