Pharmacokinetics of Rasagiline in Healthy Adult Chinese Volunteers with Various Genotypes: A Single-Center, Open-Label, Multiple-Dose Study.

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
objectiveAlthough there is evidence indicating cytochome P450 (CYP) 1A2 is responsible for the metabolism of rasagiline, the role of other CYP isoforms is unclear. This study investigated the pharmacokinetics of rasagiline in adult Chinese healthy volunteers with various CYP genotypes.
methodsThis single-center, open-label study was conducted in 12 subjects. Fasted subjects received rasagiline 1 mg daily for 7 days. Blood samples were taken to determine plasma concentrations of rasagiline, its major metabolite R-1-aminoindan (AI), and the genotyping of CYP2D6 and CYP2C19. Safety was also assessed.
resultsAfter oral administration, rasagiline was absorbed with a median time to reach maximum concentration (tmax) of 0.5 h. Overall systemic exposure was approximately theefold on day 7 versus day 1. The mean terminal elimination half-life (t½) was nearly doubled on day 7 compared to day 1. AI was rapidly quantifiable in plasma with median t max occurring 1-1.5 h post-dose. Overall exposure to AI on day 7 was approximately twofold higher than on day 1. Overall systemic exposure to AI was approximately four- to sixfold greater than exposure to rasagiline, whereas maximum concentration (C max) was approximately half that of rasagiline. The mean t½ for AI was longer than for the parent drug, and was similar between the sexes and days. Inferred metabolic status did not appear to affect the pharmacokinetics of rasagiline or AI. All adverse events were mild to moderate in severity.
conclusionMultiple oral administration of rasagiline 1 mg tablet in Chinese healthy adults resulted in similar pharmacokinetics of both rasagiline and AI compared to those previously observed in Caucasians. Rasagiline was safe and well tolerated in Chinese healthy volunteers.
