Methotrexate niosomes were formed by reverse phase evaporation technique using sorbitan monostearate (Span 60) surfactant. The pharmacokinetic parameters of methotrexate (MTX) after macrophage activation via muramyl dipeptide gelatin conjugate were studied and the results compared with those obtained after free MTX and MTX niosomes without macrophage activation. In mice MTX concentrations and tumour regression were higher after macrophage activation.

UI MeSH Term Description Entries
D008262 Macrophage Activation The process of altering the morphology and functional activity of macrophages so that they become avidly phagocytic. It is initiated by lymphokines, such as the macrophage activation factor (MAF) and the macrophage migration-inhibitory factor (MMIF), immune complexes, C3b, and various peptides, polysaccharides, and immunologic adjuvants. Activation, Macrophage,Activations, Macrophage,Macrophage Activations
D008727 Methotrexate An antineoplastic antimetabolite with immunosuppressant properties.
