Simultaneous Evaluation of Dissolution and Absorption Study of Compound Danshen Tablets and Capsules Based on Cellular Electrical Sensing Model.

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
This study explores the dissolution mechanism and absorption process of compound Danshen tablets (CDTs) and compound Danshen capsules (CDCs) in vitro. Taking the cell index as the evaluation index of dissolution and absorption of multi-component solid preparations of CDTs and CDCs, it breaks through the idea of traditional research. We used real-time cell-based assay (RTCA) to provide a new idea and method for the consistency evaluation of traditional Chinese medicine (TCM) compound preparations. The drug dissolution and absorption simulation system (DDASS) was established to obtain the dissolution and absorption samples of compound Danshen solid preparations at different time points. The cell index (CI) of the sample to H9C2 cells was detected by RTCA technology, and the dissolution and absorption percentage were calculated based on this index to obtain the dissolution and absorption kinetics model. Meanwhile, one batch of tablets and one batch of capsules (batch numbers ZKC1816 and 202101001) were selected to conduct the overall animal pharmacodynamic experiment to verify the feasibility of drug effect evaluation with cell index as an indicator. The best fitting model of dissolution curves of each batch of CDTs and CDCs is the Weibull model. There was a good correlation (r > 0.86) between the dissolution-absorption-pharmacodynamic curve. Based on RTCA technology, we have established the comprehensive evaluation method for cell biology of compound Danshen solid preparations in line with the overall concept of TCM and a synchronous evaluation system of dissolution and absorption in vitro of new TCM compound solid preparations.
