RESUMO

Multilamellar liposomal amphotericin B (L-AmB) was generally less active in vitro against yeast strains than was amphotericin B-deoxycholate or free amphotericin B, although continual agitation of the broth disproportionately increased the activity of L-AmB. Time-kill studies also demonstrated a slower onset of action of L-AmB and supported the hypothesis that liposomes may act as reservoirs for free amphotericin B, which is the active moiety.
