Nano-Spray-Drying of Cyclodextrin/Ibuprofen Complexes with Aerosolization-Enhancing Additives for Pulmonary Drug Delivery.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Cyclodextrins (CDs) enhance the solubility of poorly water-soluble drugs like ibuprofen (IBU), making them promising carriers for pulmonary drug delivery. This route lowers the required dose, minimizing side effects, which could be beneficial in treating cystic fibrosis. In this study, a nano-spray-drying technique was applied to prepare CD/IBU complexes using sulfobutylether-β-cyclodextrin (SBECD) or (2-Hydroxy-3-N,N,N-trimethylamino)propyl-beta-cyclodextrin chloride (QABCD) as carriers as well as mannitol (MAN) and leucine (LEU) as aerosolization excipients. Various investigation techniques were utilized to examine and characterize the samples, including a Master Sizer particle size analyzer, scanning electron microscopy (SEM), X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC), and Fourier-transform infrared spectroscopy (FT-IR). We applied in vitro Andersen Cascade Impactor measurements and in silico simulation analysis to determine the sample's aerodynamic properties. We also performed in vitro dissolution and diffusion tests. Applying formulations with optimal aerodynamic properties, we achieved an improved ~50% fine particle fraction values based on the Andersen Cascade Impactor measurements. The in vitro dissolution and diffusion studies revealed rapid IBU release from the formulations; however, the QABCD-based sample exhibited reduced membrane diffusion compared to SBECD due to the formation of electrostatic interactions.
