AMBISOME is an anti-fungal medicine indicated in adults and children as follows:
· Treatment of Aspergillus invasive fungal infections as a therapeutic alternative in case of voriconazole failure or intolerance.
· Treatment of Candida invasive fungal infections and neuromeningocritic cryptococcosis in HIV-infected individuals:
o Having developed renal insufficiency under amphotericin B defined by:
Elevation of serum creatinine above 220 micromol / l
§ Lower creatinine clearance below 25 ml / min.
o In case of pre-existing and persistent alteration of renal function defined by:
§ Creatinine greater than 220 micromol / l
§ Creatinine clearance less than 25 ml / min.
Empirical treatment of suspected fungal infections in febrile neutropenic patients. The maximum benefit was observed in allogeneic bone marrow transplant patients, adult patients with neutropenia greater than or equal to 7 days from the introduction of the antifungal, receiving at the same time nephrotoxic agents.
Treatment of visceral leishmaniasis in case of proven or probable resistance to antimonials.
Dosage AMBISOME 50 mg Powder for suspension of liposomes for infusion IV Box of 10 vials (+ filter) of 50 mg
· Treatment of invasive fungal infections with Aspergillus and Candida . The recommended dose is 3 mg / kg / day.
· Treatment of neuro-meningeal cryptococcosis in HIV-infected individuals. The recommended dose is 3 mg / kg / day.
· Empirical treatment of suspected fungal infections in febrile neutropenic patients. The recommended dose is 3 mg / kg / day.
· Treatment of visceral leishmaniasis: the recommended cumulative dose is 18-24 mg / kg in 6 infusions: one infusion per day for 5 consecutive days and a sixth infusion on the 10th day in the child and the immunocompetent subject.
· In immunocompromised individuals, data are limited. Doses up to 40 mg / kg over 10 to 20 consecutive days have been administered.
In case of aggravation of the renal function under AMBISOME, the continuation of the treatment must be discussed according to the estimated benefit / risk ratio. In the absence of a validated dose adjustment regimen, it is proposed to lower the doses of AMBISOME to 1.5 mg / kg / day transiently, or to temporarily space the infusions.
Clinical studies show that pediatric doses are identical to those used in adults, reported per kilogram of body weight.
No data in the elderly (≥ 65 years) can recommend a different dosing regimen than the adult.
Precautions to be taken before handling or administering the drug
For instructions on reconstitution and dilution of the drug before administration, see section Instructions for use, handling and disposal .
AMBISOME should be administered as a strict intravenous infusion for 30 to 60 minutes. If the patient feels discomfort during this infusion, the duration of the infusion can be prolonged. The recommended concentration for intravenous infusion is between 0.20 mg / ml and 2 mg / ml of AMBISOME.
AMBISOME is contraindicated in patients with known hypersensitivity to amphotericin B or any other component.
