Quantifying In Vivo Luminal Drug Solubilization -Supersaturation-Precipitation Profiles to Explain the Performance of Lipid Based Formulations.
Article in Pharmaceutical research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeTo evaluate the role of supersaturation in the in vivo absorption of fenofibrate (FFB), after oral administration in a medium-chain lipid-based formulation (MCLBF).
methodsFFB was loaded at 90% and 20% w/w of saturated solubility in MCLBF. The two formulations were pre-dispersed in purified water at 5% w/w (ME90% and 20%, respectively) and orally administered to rats to measure in vivo luminal drug concentrations.
resultsFFB precipitated in the stomach due to lipid digestion by gastric lipases and loss of solubilization capacity. This was most significant for ME90%. For ME90%, a high degree of supersaturation was also observed in the duodenum, however, precipitated FFB crystals rapidly re-dissolved. The combination of supersaturation and rapid re-dissolution appeared to drive effective absorption in the upper intestine. For ME20%, FFB precipitated in the stomach but not in the crystalline form and rapidly re-dissolved. Supersaturation in the duodenum again appeared to be the major driver of oral absorption.
conclusionsThe data provide one of the first studies of in vivo luminal drug concentration, supersaturation and absorption from lipid based formulations and suggests that for FFB, whilst very high supersaturation may drive in vitro and in vivo precipitation, re-dissolution and drug absorption is rapid and efficient.
