In situ forming gels as subcutaneous delivery systems of curcumin and piperine.

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 this study an in situ forming gel for curcumin and piperine delivery is investigated as a long-lasting strategy in the local treatment of inflammatory and degenerative joint disease, such as osteoarthritis and rheumatoid arthritis. Particularly glyceryl monooleate, in association with phosphatidylcholine and ethanol, were employed. Different ratios between excipients were tested, with the aim to obtain a liquid form suitable for subcutaneous injection, gaining a semisolid consistency in contact with biological fluids. A formulative study was conducted to assess the composition impact on the structural properties of the formulations, particularly focusing on injectability and phase transition. Curcumin and piperine were loaded, singularly or jointly, in selected in situ forming gels. Structural characterization, performed by X-ray scattering, revealed disordered reverse micellar phases, undergoing transition to hexagonal and cubic Pn3m phase upon hydration. In vitro dialysis release study demonstrated a sustained release of both drugs over 96 h, with a faster release in the case of jointly loaded drugs. Mechanistic analysis and water uptake studies indicated a drug release governed by both diffusion and swelling/erosion of the lipid supramolecular structure. Furthermore, an ex vivo release analysis performed using human skin explants suggested the formulation suitability for subcutaneous injection, indicating that the presence of piperine in the in situ formed gel allowed to double the curcumin release with respect to the simple curcumin loaded gel.
