Liposomes in treatment of infectious diseases.

In reviewing the literature about the potential of liposomes in the therapy of infections caused by protozoa, bacteria, fungi and viruses, it can be concluded that liposomal encapsulation may improve the therapeutic index of anti-infectious drugs. The improved therapeutic index may be a result of a reduction in drug toxicity and/or an enhanced drug delivery at the intracellular site of infection. Furthermore, attention is paid to the therapeutic utility of liposome-encapsulated immunomodulators in treatment of infections.
