PHARMACOLOGICAL ACTION
Artemether is a semisynthetic chiral acetal derivative of artemisimin. It interferes with parasite transport proteins, produces disruption of mitochondrial function, inhibits angiogenesis, and modulates host immune function. Artemeter and its active metabolite have been estimated to reduce parasite biomass by approximately 10,000-fold per reproductive cycle (every 2 days).
Lumafantrine is a racemic mixture of a synthetic fluorine derivative and is structurally related to guanine, mafloquine, and halofantrine. It interferes with the conversion of heme, the toxic intermediate step produced during hemoglobin break-down, to non-toxic hemozoin. Accumulation of heme and free radicals results in parasite death.
Artemether like other artemisinin derived compounds, acts quickly to rapidly reduce the parasite burden, while lumefantrine serves as a longer acting agent to eliminate remaining parasites. The combination in strains known to be resistant to traditional antimalarials such as chloroquine, and can be used for infections acquired in areas known to have parasites that are multridrug-resistant.
The mechanism of action of paracetamol is believed to be inhibition of cycloxygenase (COX), with a predominant effect on COX-2. Inhibition of COX enzymes prevents the metabolism of arachidonic acid to prostaglandin H2 an unstable intermediate byproduct which is converted to pro-inflamatory compounds.
In the central system, inhibition of COX enzymes reduces concentrations of prostaglandin E2, which lowers the hypothalamic set point to reduce fever, and activation of descending inhibitory serotonergic pathways to produce analgesia.

DRUG INTERACTIONS
Specific negative drug-drug interaction was not seen. Artemether potentiates the antimalarials. Grapefruit is known to reduce the absorption and metabolism of Artemether / Lumefantrine.
