Safety Evaluation of Nano-Liposomal Formulation of Amphotericin B (SinaAmpholeish) in Animal Model as a Candidate for Treatment of Cutaneous Leishmaniasis
AbstractBackground: Development of a topical treatment for cutaneous leishmaniasis (CL) is an important step in the improvement of lesion management. Amphotericin B (AmB) is effective against Leishmania species but it is toxic, a Nano-liposomal form of AmB with a size of about 100nm (Lip-AmB) was developed and showed to be effective against Leishmania major, and Leishmania tropica in vitro and against L. major in vivo in animal model. This study was designed to check the irritancy Draize test in rabbits and was completed in the Center for Research and Training in Skin Diseases and Leprosy, TUMS, in 2012.Methods: Twenty rabbits in 3 steps were housed individually with artificial lighting (12/12h light/dark). SinaAmpholeish cream or empty liposomes (prepared under GMP condition at Minoo Company, Tehran, Iran), was applied on a gauze patch and the patches were placed on the designated sites of the skin in the back of the rabbits. At 48 and 72h later, the erythema and oedema were checked, scored and recorded.Results: The erythema score in rabbits was 0.83+0.41 for the SinaAmpholeish and 0.5+0.55 for empty liposomes (P= 0.16). The average score for oedema was 0.67+0.52 for SinaAmpholeish and 0.33+0.52 for empty liposomes (P= 0.16).Conclusion: Based on skin irritancy reactions the topical formulation of SinaAmpholeish is safe and could be further checked in human trials.
