Effect of Probenecid on Cerebrospinal Fluid Concentrations of Penicillin and Cephalosporin Derivatives

Open access

Abstract

Probenecid may elevate the cerebrospinal fluid (CSF) concentration of penicillin G by inhibiting the excretion of organic acids from CSF. We have studied this phenomenon with various penicillin and cephalosporin derivatives. Penicillin concentrations were determined in rabbits under steady-state conditions before and after intravenous probenecid administration. With both low-dose and high-dose probenecid, CSF penicillin levels increased two to three times as did CSF concentration as a percentage of serum level. The same probenecid effect was consistently demonstrated in animals with experimental pneumococcal meningitis. Probenecid likewise increased the CSF concentration of ampicillin, carbenicillin, nafcillin, cephacatrile, and cefazolin. Probenecid may prove useful in certain bacterial infections where high CSF antibiotic levels are necessary.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
