*Ratio (90% CI) = ratio of the geometric means and 90% confidence interval for the comparison of Treatments A vs B and Treatments A vs C, respectively.
A single oral dose of 80 mg of artemether and 480 mg of lumefantrine (4 tablets) was administered to healthy adults as follows: Treatment A, fully dispersed in water; Treatment B, swallowed with water after crushing to coarse particles; Treatment C, swallowed with water without previous crushing.
