Pharmacokinetic Properties of Peramivir After Single and Multiple Intravenous Infusions in Healthy Chinese Volunteers.
Article in Clinical drug investigation, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesPeramivir, an antiviral agent for intravenous administration, is used to treat progressive influenza in patients with serious complications. The present study was designed to determine the pharmacokinetics of single and multiple intravenous infusions of peramivir in healthy Chinese subjects.
methodsSingle (150, 300 and 600 mg) and multiple (600 mg) doses of peramivir were intravenously administered to 12 healthy Chinese subjects. There was a 7-day washout period between dosing periods. Blood samples were collected in heparinized tubes at various times. Plasma peramivir and urine peramivir concentrations were measured using a high-performance liquid chromatography-tandem mass spectrometry method.
resultsFollowing single doses of peramivir (150, 300 and 600 mg), the maximum concentration (C max) values were 12,416 ± 3078, 23,147 ± 3668 and 44,113 ± 3787 µg/L, respectively, and the area under the plasma concentration-time curve (AUC) from 0 h to infinity post-dose (AUC∞) values were 24.68 ± 6.48, 47.33 ± 9.22 and 92.43 ± 12.72 mg·h/L, respectively. C max, AUC from 0 to 36 h (AUC0-36) and AUC∞ of peramivir increased proportionally with the dose, and no trend towards accumulation after multiple doses was observed. About 65 % of the peramivir was excreted unchanged in the urine within the first 24 h.
conclusionsPeramivir pharmacokinetics were dose proportional with increasing doses, with no accumulation after multiple dosing. Peramivir was generally well tolerated, and no serious adverse events occurred.
