Description
AmBisome is a liposomal formulation of amphotericin B for injection, developed by NeXstar Pharmaceuticals (acquired by Gilead Sciences in 1999). It is marketed by Gilead in Europe and licensed to Astellas Pharma (formerly Fujisawa Pharmaceuticals) for marketing in the USA, and Sumitomo Pharmaceuticals in Japan. Wikipedia
Ampholip is a lipid complex formulation of Amphotericin B marketed by Bharat Serums & Vaccines Ltd, Mumbai, India. Wikipedia
Amphotericin B (Fungilin, Fungizone, Abelcet, AmBisome, Fungisome, Amphocil, Amphotec) is a polyene antifungal drug, often used intravenously for systemic fungal infections. It was originally extracted from Streptomyces nodosus, a filamentous bacterium, in 1955 at the Squibb Institute for Medical Research from cultures of an undescribed streptomycete isolated from the soil collected in the Orinoco River region of Venezuela. Its name originates from the chemical's amphoteric properties. Two amphotericins, Amphotericin A and Amphotericin B are known, but only B is used clinically because it is significantly more active in vivo. Currently the drug is available as plain Amphotericin B, as cholesteryl sulfate complex, as lipid complex, and as liposomal formulation. The latter formulations have been developed to improve tolerability for the patient but may show considerably different pharmacokinetic characteristics compared to plain Amphotericin B. Wikipedia
Amphotericin B is well-known for its severe and potentially lethal side effects. Very often a serious acute reaction after the infusion (1 to 3 hours later) is noted consisting of high fever, shaking chills, hypotension, anorexia, nausea, vomiting, headache, dyspnea, and tachypnea, drowsiness, generalised weakness. This reaction sometimes subsides with later applications of the drug and may in part be due to histamine liberation. An increase in prostaglandin-synthesis may also play a role. This nearly universal febrile response necessitates a critical (and diagnostically difficult) professional determination as to whether the onset of high fever is a novel symptom of a fast-progressing disease, or merely the induced effect of the drug. In order to decrease the likelihood and severity of the symptoms, initial doses should be low and increased slowly. Acetaminophen, pethidine, diphenhydramine and/or hydrocortisone have all been used to treat or prevent the syndrome, but the prophylactic use of these drugs is often limited by the patient's condition. Wikipedia
Amphotericin B shows a high order of in vitro activity against many species of fungi. Histoplasma capsulatum, Coccidioides immitis, Candida species, Blastomyces dermatitidis, Rhodotorula, Cryptococcus neoformans, Sporothrix schenckii, Mucor mucedo, and Aspergillus fumigatus are all inhibited by concentrations of amphotericin B ranging from 0.03 to 1.0 mcg/mL in vitro. While Candida albicans is generally quite susceptible to amphotericin B, non-albicans species may be less susceptible. Pseudallescheria boydii and Fusarium sp. are often resistant to amphotericin B. The antibiotic is without effect on bacteria, rickettsiae, and viruses. DrugBank
Fungisome is a liposomal complex of Amphotericin B and being the latest and cheapest addition to the lipid formulations of Amphotericin B has many advantages. It is marketed by Lifecare Innovations of India. Other formulations include Amphotec (Intermune) and Abelcet (Enzon Pharmaceuticals). Wikipedia
Intravenously administered Amphotericin B has also been associated with multiple organ damage in therapeutic doses. Nephrotoxicity (kidney damage) is a frequently reported side-effect, and can be severe and/or irreversible. It is much milder when delivered via liposomes (AmBisome) if possible. Electrolyte imbalances (e.g. hypokalemia and hypomagnesemia) may also result. In the liver, increased liver enzymes and hepatotoxicity (up to and including fulminant liver failure) are common. In the circulatory system, several forms of anemia and other blood dyscrasias (leukopenia, thrombopenia), serious cardiac arrhythmias (including ventricular fibrillation), and even frank cardiac failure have been reported. Skin reactions, including serious forms, are also possible. Wikipedia

Crystalline amphotericin B is insoluble in water; therefore, the antibiotic is solubilized by the addition of sodium desoxycholate to form a mixture which provides a colloidal dispersion for intravenous infusion following reconstitution. At the time of manufacture the air in the vial is replaced by nitrogen.Last updated on RxList: 4/8/2009 RxList
Oral preparations of Amphotericin B are used to treat thrush; these are virtually nontoxic, in contrast to typical IV doses. Wikipedia

Pharmacology
Amphotericin B shows a high order of in vitro activity against many species of fungi. Histoplasma capsulatum, Coccidioides immitis, Candida species, Blastomyces dermatitidis, Rhodotorula, Cryptococcus neoformans, Sporothrix schenckii, Mucor mucedo, and Aspergillus fumigatus are all inhibited by concentrations of amphotericin B ranging from 0.03 to 1.0 mcg/mL in vitro. While Candida albicans is generally quite susceptible to amphotericin B, non-albicans species may be less susceptible. Pseudallescheria boydii and Fusarium sp. are often resistant to amphotericin B. The antibiotic is without effect on bacteria, rickettsiae, and viruses. DrugBank
Mechanism Of Action
Amphotericin B is fungistatic or fungicidal depending on the concentration obtained in body fluids and the susceptibility of the fungus. The drug acts by binding to sterols in the cell membrane of susceptible fungi with a resultant change in membrane permeability allowing leakage of intracellular components. Ergosterol, the principal sterol in the fungal cytoplasmic membrane, is the target site of action of amphotericin B and the azoles. Amphotericin B, a polyene, binds irreversibly to ergosterol, resulting in disruption of membrane integrity and ultimately cell death. DrugBank
Another IV use is as a drug of last resort in otherwise untreatable parasitic protozoan infections such as visceral leishmaniasis and primary amoebic meningoencephalitis. Mechanism of action Wikipedia
As with other polyene antifungals, amphotericin B associates with ergosterol, the main component of fungal cell membranes, forming a transmembrane channel that leads to K+ leakage and fungal cell death. Recently, however, researchers found evidence that pore formation is not necessarily linked to cell death (i.e. Angewandte Chemie Int. Ed. Engl. 2004). The actual mechanism of action may be more complex and multi-faceted. Side effects Wikipedia

Toxicity
Amphotericin B may also facilitate entry of Flucystosine into the fungal cell by interfering with the permeability of the fungal cell membrane. Diuretics or Cisplatin : Increased renal toxicity and incrised risk of hypokalemia Corticosteroids : Increased risk of hypokalemia Cytostatic drugs : Increased risk of kidney damage, hypotension and bronchospasms. Other nephrotoxic drugs : Increased risk of serious renal damage Wikipedia
