    Abstract:
    OBJECTIVE: To investigate in vivo distribution of the mitoxantrone(MIT) liposomes in SD rats after transdermal delivery. METHODS: The mitoxantrone liposomes were prepared by thin-film method. Particle size, particle distribution and delta-potential of colloid solution were obtained on laser scatterometer; the encapsulation efficiency was measured by membrane diffusion technique. The time courses of mitoxantrone concentration in vivo after the transdermal delivery of mitoxantrone liposomes were measured by HPLC assays and compared with the injection of mitoxantrone solution. RESULTS: The mean diameter of the MIT liposomes was 50.98 nm, with the entrapping efficiency of 100%. The liposomes had perfect shape. A significantly higher amount of mitoxantrone was delivered in cutis after transdermal delivery of mitoxantrone liposomes, compared with the injection of mitoxantrone solution; meanwhile, a significantly lower amount of mitoxantrone was delivered in plasma and other tissues after transdermal delivery of mitoxantrone liposomes, compared with the injection of mitoxantrone solution. CONCLUSION: Transdermal delivery of mitoxantrone liposomes could be a potential therapy for cutaneous malignant melanoma.
