Abstract

The present work investigated the topical delivery potential of nanoemulsion gel loaded with curcumin (CR). CR nanoemulsion (CR-NE) was prepared by spontaneous emulsification method using oil (Labrafac PG/glyceryl triacetate), surfactant:cosurfactant (Smix) (tween 80/polyethylene glycol [PEG] 400) and water. The pseudo-ternary phase diagrams were constructed and thermodynamic stability testing was performed. Droplet size and zeta potential were evaluated using photon correlation spectroscopy and transmission electron spectroscopy. Six formulations selected with an average droplet size ≤70±2.72 nm showed a fourfold increase in skin permeation as compared to crude CR solution in oil. The formulation CR-NE4 having a flux of 117.04±2.32 µg/cm(2)/h and with maximum retention (42.87%) was selected, characterized (droplet size =41.13±3.34 nm and zeta potential =-33.1±1.45 mV), and incorporated into gel using carbopol-980 (1% w/v). Skin dynamics analyzed by confocal laser scanning microscopy showed maximum deposition of CR up to a depth of 86.98 µm and was in concordance with differential scanning calorimetry and Fourier transform infrared spectroscopy studies that confirmed lipid bilayer disruption, enhancing permeation. A 28-day anti-arthritic evaluation (body weight, paw edema, tibiotarsal joint thickness, TNF-α and IL-1β levels, and histopathology) on Freund's complete adjuvant induced arthritic rat model after topical application of CR-NE gel in Wistar rats demonstrated substantial reversal of arthritic symptoms. Thus, CR-NE gel possesses potential for therapeutic effects locally in inflammatory arthritic disorders with improved topical bioavailability.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 July 2015.
All research outputs
#16,046,765
of 25,373,627 outputs
Outputs from International Journal of Nanomedicine
#1,887
of 4,123 outputs
Outputs of similar age
#146,207
of 277,602 outputs
Outputs of similar age from International Journal of Nanomedicine
#53
of 125 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. This one is in the 34th percentile – i.e., 34% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,123 research outputs from this source. They receive a mean Attention Score of 4.7. This one is in the 49th percentile – i.e., 49% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 277,602 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 125 others from the same source and published within six weeks on either side of this one. This one is in the 49th percentile – i.e., 49% of its contemporaries scored the same or lower than it.
