Curcuminoids are poorly water-soluble compounds with promising antimalarial activity. To overcome some of the drawbacks of curcuminoids, we explored the potential of liposomes for the intravenous delivery of curcuminoids in a model of mouse malaria. The curcuminoids-loaded liposomes were formulated from phosphatidylcholine (soy PC) by the thin-film hydration method. Antimalarial activity of curcuminoids-loaded liposomes alone and in combination with α/β arteether when administered intravenously, was evaluated in Plasmodium berghei infected mice. Animals treated with curcuminoids-loaded liposomes showed lower parasitemia and higher survival when compared to control group (no treatment). Importantly, the combination therapy of curcuminoids-loaded liposomes (40 mg/kg body wt) along with α/β arteether (30 mg/kg body wt) was able to not only cure infected mice but also prevented recrudescence. These data suggest that curcuminoids-loaded liposomes may show promise as a formulation for anti-malarial therapy.
