Investigating The Retention Potential of Chitosan Nanoparticulate Gel: Design, Development,
Article in Recent patents on anti-infective drug discovery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionThe main purpose of the research was to develop, optimize and characterize tobramycin sulphate loaded chitosan nanoparticles based gel in order to ameliorate its therapeutic efficacy, precorneal residence time, stability, targeting and to provide controlled release of the drug.
methodsBox-Behnken design was used to optimize formulation by 3-factors (chitosan, STPP and tween 80) and 3-levels. Developed formulation was subjected for characterizations such as shape and surface morphology, zeta potential, particle size, in vitro drug release studies, entrapment efficiency of drug, visual inspection, pH, viscosity, spreadability, drug content, ex vivo transcorneal permeation studies, ocular tolerance test, antimicrobial studies, isotonicity evaluation and histopathology studies.
resultsBased on the evaluation parameters, the optimized formulation showed a particle size of 43.85 ± 0.86 nm and entrapment efficiency 91.56% ± 1.04, PDI 0.254. Cumulative in vitro drug release was up to 92.21% ± 1.71 for 12 hours and drug content was found between 95.36% ± 1.25 to 98.8% ± 1.34. TEM analysis unfolded spherical shape of nanoparticles. TS loaded nanoparticulate gel exhibited significantly higher transcorneal permeation as well as bioadhesion when compared with marketed formulation. Ocular tolerance was evaluated by HET-CAM test and formulation was non-irritant and well-tolerated. Histopathology studies revealed that there was no evidence of damage to the normal structure of the goat cornea. As per ICH guidelines, stability studies were conducted and were subjected for 6 months.
conclusionResults revealed that the developed formulation could be an ideal substitute for conventional eye drops for the treatment of bacterial keratitis.
