Design and optimization of gastro-retentive microballoons for enhanced bioavailability of cinnarizine.
Trial report in Drug delivery and translational research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
This study is focused on the design of gastro-retentive drug delivery system composed of hollow microspheres (microballoons) for the sustained delivery of cinnarizine (CIN). The microballoons (MBs) were prepared by the emulsion solvent diffusion method using cellulose acetate butyrate (CAB) as the hosting polymer and absolute ethanol (ETH) and dichloromethane (DCM) as solvents. A 3(3) full factorial experimental design was adopted to study the effect of different variables and to find an optimum formula with desired properties. Prepared microballoons showed high drug loading capacities and controlled release behaviour. The optimum formulation was chosen on the basis of achieving maximum values for both drug loading capacity and release efficiency as well as having suitable size. The optimized MB (MB-F21) was composed of 200 mg CIN and 400 mg CAB with a DCM/ETH ratio of 2:1. Scanning electron microscopy for the optimum formulation showed a spherical outline with internal porous structure. An in vivo study using human volunteers was performed by determination of CIN concentration in the plasma using the liquid chromatography-mass spectrometry (LC-MS) method. Results proved the superiority of the designed formulation over the market product Stuval® tablets in bioavailability parameters comprising T max as well as area under the plasma CIN concentration-time curve (AUC0-24 h) and AUC0-∞ values. Also, the significantly greater value of mean residence time (MRT) in case of MB-F21 indicates its higher gastric residence time and proves the advantages of micro-multiparticulate dosage forms over conventional one.
