Lumefantrine (or benflumetol) is an antimalarial drug.

The term "co-artemether" is sometimes used to describe this combination.

[1] Lumefantrine has a much longer half-life compared to artemether, and is therefore thought to clear any residual parasites that remain after combination treatment.

[2] Lumefantrine, along with pyronaridine and naphthoquine, were synthesized during the Chinese Project 523 antimalaria drug research effort initiated in 1967; these compounds are all used in combination antimalaria therapies.
