The polyene antifungal agent Amphotericin B exhibits potent and broad spectrum fungicidal activity. However, high nephrotoxicity can hinder its administration in resource poor settings. Quantification of early fungicidal activity in studies of HIV patients with cryptococcosis demonstrate that 5-Fluorocytosine therapy in combination with Amphotericin B results in faster clearance than with Ampho...

Objectives: A novel topical formulation of lipid based amphotericin B (0.1% amphotericin B Gel) was developed to assess the safety, tolerability and efficacy in adult patients with cutaneous and/or mucocutaneous fungal infection. Methods: Amphotericin B gel was formulated using lipids. In vitro release assay of amphotericin B was measured using paddle apparatus maintained at 37.0° ± 0.5°C. The ...

The efficacy of liposome-encapsulated amphotericin B in the prophylaxis of disseminated Candida albicans infections in neutropenic mice was studied. The administration of liposome-encapsulated amphotericin B was associated with protection against infection with C. albicans when used at doses of greater than or equal to 2 mg of amphotericin B per kg of body weight. Neither empty liposomes nor fr...

Amphotericin B and fluconazole were compared for the treatment of experimental Candida endocarditis caused by Candida tropicalis and C. parapsilosis. Rabbits received no therapy, amphotericin B (1 mg/kg of body weight per day intravenously), or fluconazole (100 mg/kg/day intraperitoneally) for either 11 or 21 days. Against both species, amphotericin B and fluconazole were equally effective over...

Amphotericin B is a powerful but toxic drug used against fungal infections and leishmaniases. These diseases would be treated more effectively if non-toxic amphotericin derivatives could be produced on a large scale at low cost. Genetic manipulation of the amphotericin B producer, Streptomyces nodosus, has previously led to the detection and partial characterisation of 8-deoxyamphotericin B, 16...

introduction invasive mucormycosis is an opportunistic fungal infection in patients with predisposing factors. case presentation we report a case of sino-orbito-cerebral mucormycosis in a diabetic patient successfully treated with combination of liposomal amphotericin b (l-amb) and posaconazole. conclusions clinicians should be alert of the clinical presentation of this fulminant fungal infecti...

background: orbital mucormycosis caused by zygomycetes is a rare and fatal infection that generally affects the patients who  are  immunocompromised.  despite  antifungal  therapy  and  aggressive  surgical  intervention,  mucormycosis  can cause serious and rapidly fatal infections if delayed diagnosis or therapeutic management occurs. here, we report orbital mucormycosis in a healthy boy, wit...

The comparative efficacy of amphotericin B and amphotericin B methyl ester (AME) against experimental histoplasmosis, blastomycosis, cryptococcosis, and candidosis in mice was assessed by determining the effect of daily intraperitoneal therapy on 21-day survival and persistence of organisms in internal organs. AME, like amphotericin B, was effective against each of the experimental infections, ...

We developed a liposome-intercalated preparation of amphotericin B by using small, unilamellar vesicles 0.06 to 0.1 micron in diameter. In contrast to previously described liposomal preparations of amphotericin B, these vesicles have the advantage that they are small enough to be filter sterilized. We compared the efficacy of liposomal amphotericin B with that of the commercial drug given as an...
