Inhibition of [3H]cephalexin (0.1 mM) uptake by cephalexin (25 mM), acyclovir (0.5 mM) and valine esters of acyclovir (0.5 mM)
Inhibition is expressed as a percentage of control uptake (pmol/mg protein/min). Results are the mean ± S.E.M. of at least three determinations.
↵3-a Significantly different from control at P < .01.
↵3-b Significantly different from control at P < .05.
