Evaluation of Prosopis africana Seed Gum as an Extended Release Polymer for Tablet Formulation.

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
In the present work, an attempt has been made to screen Prosopis africana seed gum (PG), anionic polymer for extended release tablet formulation. Different categories of drugs (charge basis) like diclofenac sodium (DS), chlorpheniramine maleate (CPM), and ibuprofen (IB) were compacted with PG and compared with different polymers (charge basis) like xanthan gum (XG), hydroxypropyl methyl cellulose (HPMC-K100M), and chitosan (CP). For each drug, 12 batches of tablets were prepared by wet granulation technique, and granules were evaluated for flow properties, compressibility, and compactibility by Heckel and Leuenberger analysis, swelling index, in vitro dissolution studies, etc. It has been observed that granules of all batches showed acceptable flowability. According to Heckel and Leuenberger analysis, granules of PG-containing compacts showed similar and satisfactory compressibility and compactibility compared to granules of other polymers. PG showed significant swelling (P < 0.05) compared to HPMC, and better than CP and XG. Differential scanning calorimetry (DSC), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) study showed no interaction between drugs and polymers. From all PG-containing compacts of aforesaid drugs, drug release was sustained for 12 h following anomalous transport. Especially, polyelectrolyte complex formation retarded the release of oppositely charged drug (CPM-PG). However, extended release was noted in both anionic (DS) and nonionic (IB) drugs, maybe due to swollen gel. All compacts were found to be stable for 3-month period during stability study. This concludes that swelling and release retardation of PG has close resemblance to HPMC, so it can be used as extended release polymer for all types of drugs.
