Nanoliposomes Embedded Nanocochleates for Codelivery of Artemether and Lumefantrine: An In Vitro and In Vivo Study.
Antimalarial drugs are being encapsulated in nanotechnology-based carriers because there are not enough new treatment options and people are becoming more resistant to the ones that are already available. This approach uses two or more biochemical targets of malarial parasites. The codelivery of artemether and lumefantrine (AL) combines the synergistic effect of artemether for an early onset of action followed by the prolonged effect of lumefantrine. The bioavailability of artemether and lumefantrine is low due to their low solubility. Thus, an alternative lipidic formulation, namely nanocochleate, was developed for the selected drugs by adding calcium ions into preformed nanoliposomes (AL-loaded liposomes). Using phospholipon 90H and cholesterol, a thin-film hydration method produced drug-loaded liposomes. The synthesized AL-loaded liposomes were further incorporated into nanocochleates. The formulations were evaluated for in vitro and in vivo parameters. Nanocochleates had a particle size of 200.7 nm, a zeta potential of -9.4 mV, and an entrapment efficiency of 73.12% ± 1.82% and 61.46% ± 0.78%, respectively, for artemether and lumefantrine. Whereas liposomes had a particle size of 210 nm and an entrapment efficiency of 67.34% ± 1.52% and 53.24% ± 0.78%, respectively, for artemether and lumefantrine. An X-ray diffraction study confirmed the amorphous state of artemether and lumefantrine in liposomes and nanocochleate. Nanocochleate showed a controlled release profile for loaded drugs. When compared with free drugs, nanocochleate showed low tissue distribution and a 20-fold increase in bioavailability in rats. Thus, nanocochleate offers an interesting alternative to an existing dosage form for the treatment of malaria.
