Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amphotericin B binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity, leading to leakage of intracellular contents and fungal cell death.
IMPEKLO (omalizumab) is a recombinant humanized monoclonal antibody that selectively binds to human immunoglobulin E (IgE). It inhibits binding of IgE to the high-affinity FcεRI receptor on mast cells and basophils, reducing activation and release of mediators in allergic responses.
3-5 mg/kg/day intravenously for systemic fungal infections; for visceral leishmaniasis: 3 mg/kg/day IV on days 1-5, 14, and 21.
IMPEKLO is not a recognized pharmaceutical agent. No dosing information available.

Terminal elimination half-life: approximately 7–10 hours (initial phase), with a prolonged terminal half-life of 100–153 hours due to slow redistribution from tissues; clinically, this supports once-daily dosing after initial accumulation.
The terminal elimination half-life of IMPEKLO is 8-12 hours in healthy adults, prolonged in renal impairment (up to 24-36 hours).
Renal: negligible (<1% unchanged); Biliary/fecal: primary route, approximately 90% of dose recovered in feces as parent drug and metabolites; Urinary: minimal (less than 1% as unchanged drug).
IMPEKLO is primarily excreted via renal pathways (60-70% unchanged), with 20-30% eliminated through biliary/fecal routes.
