Pharmacokinetics and ex vivo susceptibility of cefpodoxime proxetil in patients receiving continuous ambulatory peritoneal dialysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Pharmacokinetics of cefpodoxime, an extended-spectrum cephalosporin, were determined for eight noninfected patients on continuous ambulatory peritoneal dialysis (CAPD) and eight healthy volunteers. Subjects were matched for sex, age (+/- 6 years), and body weight (+/- 10 kg, except for one pair) and received a single 200-mg (cefpodoxime equivalents) oral dose of the prodrug cefpodoxime proxetil in an open-label, paired-design fashion. Dialysate (CAPD group only), plasma, and urine samples were collected and assayed for cefpodoxime by a microbiologic method. In addition, mean bactericidal titers of the effluent dialysate against selected bacterial strains often associated with CAPD-related peritonitis were determined at 6 and 24 h after the dose. There was a significant difference (P < 0.05) in all pharmacokinetic parameters between healthy and CAPD subjects, except for lag time to absorption. The mean peak plasma cefpodoxime concentration of 1.88 +/- 0.6 micrograms/ml occurred at 2.44 +/- 0.5 h for healthy volunteers, while the peak concentration of 3.25 +/- 1.4 micrograms/ml occurred at 12.0 +/- 4.2 h for patients on CAPD. The average elimination half-life in CAPD patients was approximately 12 times greater than that seen in healthy volunteers. Peritoneal dialysis had a minimal effect on cefpodoxime clearance. In healthy volunteers, 24.2% +/- 13% of the dose was recovered from the urine, in contrast to only 5.59% +/- 6.9% for CAPD patients. The mean bactericidal titers for all CAPD patients, at 6 and 24 h, were mostly less than 1:2 and did not exceed 1:4 for any of the isolates. Because of the decreased renal clearance and negligible dialysate clearance of cefpodoxime, and delayed drug absorption, the dosage interval for cefpodoxime proxetil may need to be extended in CAPD patients.
