The Ameliorated Pharmacokinetics of VP-16 in Wistar Rats: A Possible Role of P-Glycoprotein Inhibition by Pharmaceutical Excipients.
Article in European journal of drug metabolism and pharmacokinetics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND AND
objectivesThe selection of suitable functional excipients with low toxicity index and having P-glycoprotein inhibitory characteristics represents a major innovative step in designing a promising formulation for oral chemotherapy. This study was aimed at investigating the chemosensitizing effect of selected pharmaceutical excipients to improve the in vivo pharmacokinetic performance of VP-16.
methodsThe pharmaceutical excipients having P-glycoprotein inhibitory activity were screened by shake flask method for their VP-16 solubilization capacity. The cumulative amount of VP-16 was determined with or without the selected pharmaceutical excipients at three different concentrations (0.1 % w/v, 0.5 % w/v and 1 % w/v) by an everted gut sac technique. Moreover, pharmacokinetic studies were also performed to determine the oral bioavailability assessment of VP-16 in albino male Wistar rats.
resultsThe absorptive transport from mucosal-to-serosal (M → S) and secretory transport from serosal-to-mucosal (S → M) for VP-16 solution over 90 min were found to be (3.58 ± 0.32) × 10
conclusionThe findings suggest that pharmaceutical excipients may be employed in the development of drug delivery systems to improve the oral bioavailability of drugs having low solubility and/or less permeability as a result of substantial P-glycoprotein mediated efflux.
