Glyceroniosomes for enhanced intestinal absorption of hydrochlorothiazide and lisinopril in their fixed dose combination.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The objective was to investigate the effect of co-administration of hydrochlorothiazide and lisinopril as fixed dose combination on their intestinal absorption. The scope was extended to enhance intestinal absorption of both drugs. In situ rabbit intestinal absorption through the duodenum and jejuno-ileum was used to monitor membrane permeability of both drugs when perfused alone or in combination. Niosomes containing glycerols (glyceroniosomes) were loaded with both drugs. Glyceroniosomes comprised Span 60 or Tween 40 in combination with cholesterol and glycerol were prepared by bath sonication. Glyceroniosomes were characterized with respect to vesicle size, drug entrapment efficiency and were examined using transmission electron microscope (TEM). The prepared vesicles were nanosized spherical vesicles with average size of 202.4 nm and 108.8 nm for span free and span containing glyceroniosomes, respectively. The recorded Zeta potential values suggested good stability of the prepared formulations. Intestinal absorption studies reflected incomplete absorption of hydrocholothiazide and lisinopril correlating with their categorization as class IV and III drugs, respectively. Co-perfusion of both drugs reduced the intestinal absorption of lisinopril. Simultaneous encapsulation in glyceroniosomes enhanced the intestinal absorption of both drugs. Tween based systems were more efficient. The study introduced glyceroniosomes as carriers of simultaneous delivery of hydrochlorothiazide and lisinopril.
