[Aqueous-and serum levels of cephalexin and penicillin V after oral application in man (author's transl)].
This clinical study implies orally administered cephalexin and penicillin V as agents with effective aqueous homor penetration in noninfected human eyes. Aqueous humor concentration of cephalexin increases up to 15% of the serum level 2 h after application. Administration of 1 g or 2 g cephalexin revealed no significant difference in aqueous humor concentration.  So penetration of blood-aqueous-humor barrier can be regarded as a saturation process. Individual results of 92 cephalexin determinations are variant and not related to body weight or age of the patients.
