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

The aim of this study was to increase both the rates of dissolution and bioavailability of the amlodipine (Amlo) drug. Due to the low cost, high solubility, and amorphous state, polyvinylpyrrolidone (PVP) has been used as a drug carrier in the solid dispersion process. Through applying an irradiation technique, powder of (PVP) is irradiated with six 0-50 kGy irradiation doses. The six irradiated (PVP) samples were characterized using gel permeation chromatography, electron spin resonance, and Fourier transform infrared (FT-IR) spectroscopy. The formulation of six (PVP/Amlo) samples at a ratio of 2:1 wt/wt were characterized using FT-IR spectroscopy and X-ray powder diffraction. In vitro dissolution of (Amlo) drug was assessed in a water solvent at pH 1.2 and pH 7. Results demonstrated that there is a change in the physicochemical properties of irradiated (PVP). FT-IR confirmed that there is an intermolecular H bond between the (Amlo) drug and (PVP) polymer. XRD confirmed that (PVP) changes the crystalline (Amlo) to amorphous amlodipine. Irradiated (PVP) at a dose of 20 kGy released approximately 89% from 40 mg of (Amlo) in 60 s. The in vitro rate of amlodipine dissolution depends on the drug-polymer intermolecular H bond. The rate of (Amlo) dissolution is increased due to the drug-drug intramolecular hydrogen bonding replaced with the drug-polymer intermolecular hydrogen bonding, which reduces the crystal packing. Irradiated (PVP) improved the rate of (Amlo) dissolution compared to unirradiated (PVP).
