FIG. 3.

Mean plasma oseltamivir carboxylate concentrations (± standard error of the mean) versus time in three groups of healthy human subjects after 2 weeks of oseltamivir administration. Group 1 (solid diamonds, dashed line) received oseltamivir 75 mg q24h; group 2 (solid squares, solid line) received oseltamivir 75 mg q48h plus probenecid 500 mg QID; and group 3 (open triangles, solid line) received oseltamivir 75 mg q48h plus probenecid 500 mg BID. Error bars indicate standard errors of the means.
