Fungizone (Amphotericin B) - Summary

FUNGIZONE SUMMARY

FUNGIZONE^® INTRAVENOUS
Amphotericin B For Injection USP

FUNGIZONE intravenous (Amphotericin B for Injection) contains amphotericin B, an antifungal polyene antibiotic obtained from a strain of Streptomyces nodosus.

FUNGIZONE (amphotericin B) is indicated for the following:

FUNGIZONE Intravenous (Amphotericin B for Injection USP) should be administered primarily to patients with progressive, potentially life-threatening fungal infections. This potent drug should not be used to treat noninvasive fungal infections, such as oral thrush, vaginal candidiasis and esophageal candidiasis in patients with normal neutrophil counts.

FUNGIZONE Intravenous is specifically intended to treat potentially life-threatening fungal infections: aspergillosis, cryptococcosis (torulosis), North American blastomycosis, systemic candidiasis, coccidioido-mycosis, histoplasmosis, zygomycosis including mucormycosis due to susceptible species of the genera Absidia, Mucor and Rhizopus, and infections due to related susceptible species of Conidiobolus and Basidiobolus, and sporotrichosis.

Amphotericin B may be useful in the treatment of American mucocutaneous leishmaniasis, but it is not the drug of choice as primary therapy.

Published Studies Related to Fungizone (Amphotericin B)

A phase II randomized trial of amphotericin B alone or combined with fluconazole in the treatment of HIV-associated cryptococcal meningitis. [2009.06.15]
BACKGROUND: Cryptococcosis is a life-threatening infection among patients with human immunodeficientcy virus (HIV) infection. Therapeutic options for the treatment of central nervous system cryptococcosis are limited, especially in resource-limited settings... CONCLUSIONS: AmB plus fluconazole administered at a dosage of 800 mg for 14 days, followed by fluconazole administered at a dosage of 800 mg daily for 56 days, is well-tolerated and efficacious among HIV-positive patients with central nervous system cryptococcosis. These results have significant treatment implications and should be validated in a randomized phase III trial.

Economic impact of caspofungin as compared with liposomal amphotericin B for empirical therapy in febrile neutropenia in Australia. [2009.06]
BACKGROUND: In a major clinical trial, caspofungin was as efficacious as liposomal amphotericin B (LAmB) for empirical therapy in febrile neutropenia. The current study sought to evaluate the economic impact of caspofungin as compared with LAmB for febrile neutropenia in Australia... CONCLUSIONS: This is the first economic study to evaluate the place of caspofungin as empirical therapy in Australia. Caspofungin is more cost-beneficial than LAmB, which contradicts the current Australian guidelines of recommending LAmB as the first choice for empirical therapy.

Postoperative application of amphotericin B nasal spray in chronic rhinosinusitis with nasal polyposis, with a review of the antifungal therapy. [2009.06]
Chronic rhinosinusitis (CRS) affects 1-4% of the adult population. The etiology of this multifactorial, chronic disease, which leads to a significant impairment of the quality of life, often accompanied by nasal polyposis, is not fully understood...

A prospective randomized controlled trial comparing PCR-based and empirical treatment with liposomal amphotericin B in patients after allo-SCT. [2009.04]
We compared the efficacy and safety of empirical plus PCR-based vs empirical liposomal amphotericin B treatment after Allo-SCT. Allo-SCT recipients were randomized to receive either PCR-based preemptive therapy (group A; n=198) or empirical antifungal therapy (group B; n=211) with liposomal amphotericin B...

The effect of topical amphotericin B on inflammatory markers in patients with chronic rhinosinusitis: a multicenter randomized controlled study. [2009.02]
BACKGROUND: It has been suggested that an exaggerated immune response to fungi is crucial in the pathogenesis of chronic rhinosinusitis (CRS). Based on this rationale, the use of topical antifungals (amphotericin B) has been advocated. Studies on its clinical effectiveness are, however, contradictory. OBJECTIVES: To examine the effect of nasal antifungal treatment on secreted mediators in samples of nasal lavage fluid from patients with CRS with or without nasal polyps (NP)... CONCLUSIONS: Topical amphotericin B has no significant effect on activation markers of nasal inflammatory cells in chronic rhinosinusitis with or without nasal polyps.

Clinical Trials Related to Fungizone (Amphotericin B)

Pharmacokinetic Profiles of Inhaled Lipid Complex Amphotericin B (Abelcet ®) [Completed]
The purpose of this study is to determine the optimal delivery system for the nebulization of the lipid complex amphotericin B (Abelcet ®) in lung transplant recipients who are positive for invasive aspergillosis (IA) in their lungs. Additionally, the investigators hope to determine the concentrations of amphotericin B achieved in the epithelial lining fluid, and serum with the administration of four days of lipid complex of amphotericin B (Abelcet ®) (QD) via aerosolized nebulization

A Study of Caspofungin, Liposomal Amphotericin B or the Combination of Both for Patients After Stem-Cell Transplantation [Completed]
The study compares the safety, efficacy and pharmacokinetics of caspofungin, liposomal amphotericin B or the combination of both in the antifungal treatment of adult patients after allogeneic haematopoietic stem-cell transplantation with granulocytopenia and persistent i. g. recurrent fever under adequate antibacterial therapy.

A Phase II Study To Assess Safety and Efficacy Of Short-Course Regimens Of Amphotericin B Emulsion In Kala-Azar [Completed]
1. To evaluate the Safety and Efficacy of four different short-course regimens of Amphotericin B emulsion in treatment of Kala-azar (visceral leishmaniasis) subjects who are either treatment naive or treatment resistant to other antileishmanial drugs except amphotericin B containing preparations.

2. To assess the safety and efficacy of single-bolus infusion of Amphotericin B emulsion in treatment of Kala-azar.
