Cetirizine from topical phosphatidylcholine-hydrogenated liposomes: evaluation of peripheral antihistaminic activity and systemic absorption in a rabbit model.
Article in The AAPS journal, 2004. 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
Cetirizine, an effective, minimally sedating, second-generation H1-antihistamine is widely used orally to treat allergic skin disorders. This study was performed to assess the peripheral H1-antihistaminic activity and extent of systemic absorption of cetirizine from liposomes applied to the skin. Cetirizine was incorporated into small unilamellar vesicles (SUV) and multilamellar vesicles (MLV) prepared using L-alpha-phosphatidylcholine hydrogenated (HPC), and into Glaxal Base (GB) as the control. In a randomized, crossover study, each formulation, containing 10 mg of cetirizine, was applied to the depilated backs of 6 rabbits (3.08 +/- 0.05 kg). Histamine-induced wheal tests and blood sampling were performed before cetirizine application and at designated times for up to 24 hours afterwards. Compared with baseline, histamine-induced wheal formation was suppressed by cetirizine in SUV only at 24 hours, in MLV from 0.5 to 24 hours, and in GB from 0.5 to 8 hours (P < or = .05). Wheal suppression by cetirizine in SUV at 24 hours (91.7% +/- 5.2%) and in MLV from 1 to 24 hours (93.8% +/- 2.2% to 76.2% +/- 6.5%) was greater than in GB (36.5% +/- 7.4% to 60.6% +/- 14.2%) from 1 to 24 hours (P < or = .05). Faster onset, as well as greater and more persistent suppression was obtained from cetirizine in MLV. Plasma cetirizine concentrations from MLV (area under the curve [AUC] of 221.2 +/- 42.3 ng x hr/mL) were lower than from GB (AUC of 248.3 +/- 34.6 ng.hr/mL). In this model, cetirizine from MLV had excellent topical H(1)-antihistamine activity, while systemic exposure was reduced, compared with cetirizine from GB.
