Abstract
The therapeutic activity of nystatin (NYS) incorporated in multilamellar liposomes (L-NYS) was studied in vivo. Hale-Stoner mice injected intravenously with various doses of L-NYS and free NYS showed a significant reduction in toxicity of NYS after the NYS was incorporated into liposomes (maximal tolerated doses, 16 and 4 mg/kg of body weight, respectively). The maximal tolerated dose of free NYS had no effect in the treatment of mice infected with Candida albicans, whereas L-NYS at an equivalent dose improved the survival of mice. A marked increase in survival was observed when L-NYS was administered in higher and multiple doses (total doses up to 80 mg/kg). Liposome encapsulation thus provided a means for intravenous administration of NYS, reducing its toxicity and making it an active systemic antifungal agent.
