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

Pharmaceutical cocrystals are a promising strategy to increase the solubility and dissolution rate of poorly soluble drugs. However, their manufacturing process requires a large quantity of solvents. The present study aimed to produce cocrystals by a solvent-free hot melt extrusion (HME) method to improve their solubility and dissolution rate. Aripiprazole (ARP) and adipic acid (ADP) were used as a weakly basic drug and acidic coformer, respectively. The processability of a plain ARP-ADP physical mixture (PM) compared with a PM with 5% Soluplus® (SOL) was investigated. Incorporating 5% SOL into the ARP-ADP blend reduced the processing torque and improved processability. The effects of temperature and screw speed on the formation of cocrystals were studied, and cocrystals were characterized by differential scanning calorimetry (DSC), fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, powder X-ray diffraction (PXRD), scanning electron microscopy, and hot-stage microscopy. FTIR spectra revealed noncovalent interaction between ARP and ADP, which was confirmed by NMR spectra. Similarly, PXRD data exhibited characteristic peaks confirming the formation of new crystalline material. Further, the results indicated that cocrystals demonstrated higher dissolution rates and improved compressibility, as well as enhanced flow characteristics compared with pure ARP, suggesting its suitability in the development of solid dosage forms.
