Dry Powder Inhaler of Sustained-Release Microspheres Containing Glycyrrhizin: Factorial Design and Optimization.

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
backgroundGlycyrrhizin is a saponin glycoside of the liquorice plant. It is commonly used to treat respiratory problems. Inhalable glycyrrhizin formulation in asthma can be a good alternative for widely used inhaled corticosteroids that exhibit side effects upon long-term use.
aimAsthma is a major and prevalent respiratory disease. However, the rate of drug development in this arena is quite slow, as indicated by merely four new drugs approved by the USFDA in the last 6 years for respiratory diseases.
objectiveWe herein propose to design and develop Glycyrrhizin-inhalable microspheres for the treatment of asthma.
methodA 3
resultsThe optimized microspheres were spherical and 1-5 μm in size. The formulation showed a fine particle fraction of 78%, indicating that the powders were suitable for inhalation. The Drug loading and encapsulation efficiency of the optimized formulation were found to be 9.8% and 40.98%, respectively. The aerosolization study on the Anderson cascade impactor showed that deposition of particles of formulation blended with lactose was better than nonblended formulation and drug in the lungs.
conclusionIn comparison to the pure drug, optimized formulation prolonged drug residency in the lung for more than 12 hrs after inhalation. Inhalable microparticles of glycyrrhizin provide sustained and prolonged drug release in the lungs along with protection of drugs against pulmonary degradation.
