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

purposePreparation and evaluation of topical ophthalmic formulations containing nimodipine-CD complexes prepared using HP-β-CD, SBE-β-CD and M-β-CD for the management of glaucoma.

methodsNimodipine-CD complexes were prepared using a freeze-drying method. Two different molar ratios (NMD:CD) were used for each cyclodextrin. The inclusion complexes were characterized using DSC, FTIR, yield (%), drug content and in vitro release characteristics. NMD-CD complexes incorporated into chitosan eye drops and a temperature-triggered in situ gelling system were evaluated for their pH, viscosity and in vitro release characteristics. We determined the intraocular pressure (IOP) lowering effect of NMD-hydroxypropylmethylcellulose (HPMC) eye drops through a single dose response design using C57BL/6J mice. The minimum effective concentration (MEC) of nimodipine was further applied to mice that vary in the parental allele of Cacna1s, the drug target of nimodipine. Cytotoxicity was also evaluated.

resultsOur ophthalmic formulations possessed pH and viscosity values that are compatible with the eye. In vitro release of nimodipine was significantly increased from chitosan eye drops containing NMD-CD complexes compared to uncomplexed drug. Administration of nimodipine can lower IOP significantly after a single drop of drug HPMC suspension. The IOP-lowering response of the MEC (0.6%) was significantly influenced by the parental allele of Cacna1s.

conclusionsNimodipine can be used as a promising topical drug for management of glaucoma through ocular delivery.
