Encapsulation of amphotericin B in liposomes or complexing of the compound with other lipid carriers brings about a major reduction in toxicity. Although animal experimental studies have shown an increased therapeutic index for a variety of such lipid formulations resulting in higher dose-dependent efficacy rates, clinical data on pharmacokinetics and efficacy are still scanty. AmBisomeR, Amphotericin B Lipid Complex (ABLC) and AmphocilR (Amphotericin B Colloidal Dispersion, ABCD) have quite different structural and pharmacokinetic characteristics; however, it is not clear whether these differences are important with respect to tolerance and efficacy. At this moment, most published clinical data are available for AmBisomeR, which shows encouraging results in a variety of invasive fungal infections. AmBisomeR has been safely administered in high dosages up to 5 mg/kg/day. Randomized comparative trials with liposomal and other lipid-complexed amphotericin B formulations versus conventional amphotericin B are urgently needed to assess their respective clinical values.

UI	MeSH Term	Description	Entries
D008055	Lipids	A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids.

D008081	Liposomes	Artificial, single or multilaminar vesicles (made from lecithins or other lipids) that are used for the delivery of a variety of biological molecules or molecular complexes to cells, for example, drug delivery and gene transfer. They are also used to study membranes and membrane proteins.

D004337	Drug Carriers	Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.

D000666	Amphotericin B	Macrolide antifungal antibiotic produced by Streptomyces nodosus obtained from soil of the Orinoco river region of Venezuela.	Amphocil,Amphotericin,Amphotericin B Cholesterol Dispersion,Amphotericin B Colloidal Dispersion,Fungizone
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
