A comparison of ebastine 10 mg fast-dissolving tablet with oral desloratadine and placebo in inhibiting the cutaneous reaction to histamine in healthy adults.

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
objectiveEbastine is a long-acting, second-generation selective histamine H(1) receptor antagonist. The pharmacodynamics of a new 10mg fast-dissolving tablet (FDT) oral lyophilisate tablet formulation of ebastine were compared with those of desloratadine and placebo following histamine skin intradermal test challenge. The acceptability of the FDT was also assessed.
methodsThis was a double-blind, double-dummy, placebo-controlled, randomised, crossover, three-period study in 36 healthy adults. The histamine skin intradermal test (0.05 mL of 100 microg/mL solution) was administered into volunteers' forearms, and wheal area was measured 15 minutes later. Ebastine 10 mg FDT, desloratadine 5mg capsule or placebo were given on days 1-5. On day 1, a skin intradermal test was performed at baseline, then every 20 minutes for 2 hours after administration and at 24 hours. The final skin intradermal test was on day 6, 24 hours after the last drug dose. Subjective symptoms (itching, heat and pain) were assessed on day 1 for 2 hours following the first drug dose. There was a washout period of 7-10 days between treatments. At study end, the acceptability of the new ebastine formulation was evaluated using a questionnaire.
resultsEbastine 10mg inhibited the wheal response to histamine significantly more than desloratadine 5 mg or placebo 24 hours after 5 days' treatment (mean difference between treatments in wheal area reduction from baseline: 26.7%, p < 0.0001; 46.9%, p < 0.0001, respectively), and after 24 hours on day 1 (mean difference: 16.2%, p = 0.0082; 34.2%, p < 0.0001, respectively). The results with desloratadine were also significantly different from placebo on day 1 and after 5 days, but less than with ebastine after 5 days (difference, desloratadine vs placebo: 20.2%, p = 0.0001). No differences in itching, heat and pain were observed between the treatments. Most participants (70%) preferred the FDT, and all reported that it made adherence easier.
conclusionEbastine 10 mg FDT demonstrated significantly superior antihistamine activity compared with desloratadine and placebo.
