Amphotericin B stands as a formidable agent in the fight against a spectrum of serious fungal infections, a testament to its potent mechanism of action. As a polyene antifungal, its primary mode of operation involves binding to ergosterol, a vital component of the fungal cell membrane. This interaction leads to the formation of pores, causing an irreversible leakage of essential intracellular ions and molecules, culminating in fungal cell death. This direct fungicidal effect makes it a critical component in the treatment for invasive fungal diseases, especially when other agents may fail or when rapid action is required.

However, the efficacy of Amphotericin B is often shadowed by its considerable side effect profile. Commonly referred to as 'amphoterrible', it can cause a range of adverse reactions, including fever, chills, nausea, vomiting, and importantly, significant renal toxicity. Understanding these side effects of Amphotericin B is paramount for clinicians when selecting appropriate Amphotericin B drug interactions to consider, as it can influence the choice of co-administered medications. The development of lipid formulations has significantly mitigated these toxicities, offering a safer therapeutic window without compromising its antifungal prowess.

The therapeutic applications of Amphotericin B are extensive. It is a first-line treatment for severe systemic fungal infections such as invasive aspergillosis, cryptococcosis, and mucormycosis. Beyond its antifungal capabilities, it is also employed in the treatment of certain protozoan infections, notably visceral leishmaniasis. The availability of various Amphotericin B formulations, including conventional deoxycholate and advanced lipid-based preparations, allows for a personalized approach to patient care.
