1 · What the graph read from it

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.

2 · The registry

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

backgroundThe antiepileptic drug lacosamide has a low potential for drug-drug interactions, but is a substrate and moderate inhibitor of the cytochrome P450 (CYP) enzyme CYP2C19.

objectiveThis phase I, randomized, open-label, two-way crossover trial evaluated the pharmacokinetic effects of lacosamide and omeprazole coadministration.

methodsHealthy, White, male volunteers (n = 36) who were not poor metabolizers of CYP2C19 were randomized to treatment A (single-dose 40 mg omeprazole on days 1 and 8 together with 6 days of multiple-dose lacosamide [200-600 mg/day] on days 3-8) and treatment B (single doses of 300 mg lacosamide on days 1 and 8 with 7 days of 40 mg/day omeprazole on days 3-9) in pseudorandom order, separated by a ≥ 7-day washout period. Area under the concentration-time curve (AUC) and peak concentration (C(max)) were the primary pharmacokinetic parameters measured for lacosamide or omeprazole administered alone (reference) or in combination (test). Bioequivalence was determined if the 90 % confidence interval (CI) of the ratio (test/reference) fell within the acceptance range of 0.8-1.25.

resultsThe point estimates (90 % CI) of the ratio of omeprazole + lacosamide coadministered versus omeprazole alone for AUC (1.098 [0.996-1.209]) and C(max) (1.105 [0.979-1.247]) fell within the acceptance range for bioequivalence. The point estimates (90 % CI) of the ratio of lacosamide + omeprazole coadministration versus lacosamide alone also fell within the acceptance range for bioequivalence (AUC 1.133 [1.102-1.165]); C(max) 0.996 (0.947-1.047).

conclusionSteady-state lacosamide did not influence omeprazole single-dose pharmacokinetics, and multiple-dose omeprazole did not influence lacosamide single-dose pharmacokinetics.
