AMBISOME vs HALOTEX
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.
Halotex (haloprogin) is a topical antifungal agent that disrupts fungal cell membrane permeability and inhibits ergosterol synthesis, leading to cell death.
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.
Apply topically twice daily for 2-4 weeks; tinea pedis may require up to 6 weeks.

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.
Not well characterized; estimated terminal half-life approximately 24-48 hours based on limited data.
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).
Primarily fecal (biliary) as unchanged drug and metabolites; negligible renal excretion (<1%).
