Green solvent-based synthesis of diclofenac diethylamine-loaded PCL nanoparticles for sustained drug delivery
Article
作者: Ajji, Zaki Ali ; Al-Laham, Antoun ; Soliman, Soolafa Al
BACKGROUND:
Diclofenac, a non-steroidal anti-inflammatory drug (NSAID), has demonstrated promising antitumor properties; however, its clinical application is limited by systemic toxicity. Encapsulation in biodegradable polymeric nanoparticles offers a strategy to enhance therapeutic efficacy while minimizing adverse effects. Nevertheless, the use of toxic organic solvents in nanoparticle fabrication remains a significant challenge.
OBJECTIVE:
This study aimed to develop and characterize diclofenac diethylamine-loaded polycaprolactone (PCL) nanoparticles using green solvents and to compare two preparation methods-emulsification solvent evaporation/extraction and spontaneous emulsification solvent diffusion-for producing diclofenac-loaded nanoparticles with potential applications in tumor therapy.
METHODS:
Diclofenac diethylamine-loaded PCL nanoparticles were prepared using both methods, employing a novel green solvent system. The nanoparticles were characterized in terms of size, polydispersity index (PDI), zeta potential, morphology, and encapsulation efficiency. In vitro drug release profiles were evaluated and fitted to kinetic models.
RESULTS:
The developed diclofenac diethylamine-loaded PCL nanoparticles exhibited a mean diameter below 200 nm, a monodisperse population, and a negative surface charge. Both preparation methods achieved high encapsulation efficiency and prolonged, diffusion-controlled drug release. The spontaneous solvent diffusion method provided slightly better control over particle size.
CONCLUSION:
These nanoparticles are well-suited for cancer therapy, offering sustained drug release, enhanced safety due to the use of green solvents, and robust physicochemical stability. The findings support their potential as an innovative, effective, and safe delivery system for antitumoral applications.

[Electroacupuncture at neuro-arterial stimulation points for post-stroke shoulder-hand syndrome: a randomized controlled trial].
Article
作者: Zhao, Meidan ; Wu, Jiazhu ; Liu, Zhixin ; Yin, Xiumei ; Xu, Zhifang ; DU, Yuanhao ; Zhang, Man
Objective:
To compare the clinical efficacy of electroacupuncture (EA) at neuro-arterial stimulation points with topical western medication in treating post-stroke shoulder-hand syndrome (SHS).
Methods:
A total of 72 patients with post-stroke SHS were randomly assigned to an observation group (n=36, 2 cases dropped out) and a control group (n=36, 3 cases dropped out). Both groups received standard neurological treatment, comprehensive rehabilitation, and physical therapy. The observation group received EA at neuro-arterial stimulation points, including the ipsilateral stellate ganglion point, vagus nerve trunk and auricular branch (left side), and stimulation points of the radial and ulnar arteries, radial nerve, ulnar nerve, and median nerve, once daily for 4 weeks. The control group was treated with topical diclofenac diethylamine emulgel, and mucopolysaccharide polysulfate cream was added for patients with pronounced early-stage edema, twice a day for 4 weeks. The VAS pain score and hand edema volume were recorded before treatment, at 2 and 4 weeks during treatment, and 2 weeks after treatment completion (follow-up). Musculoskeletal ultrasound was used to measure the thickness of the dorsal hand and middle finger skin on the affected side before and after 4 weeks of treatment.
Results:
Compared before treatment, the VAS pain scores and edema volume of the affected hand in both groups were decreased at week 2, week 4, and follow-up (P<0.05). At week 4, both groups showed lower VAS pain scores and edema volume than those at week 2 (P<0.05); during follow-up, both VAS pain scores and edema volume were further reduced compared to those at week 4 (P<0.05). At week 2, week 4, and follow-up, the VAS scores and edema volume of the affected hand in the observation group were lower than those in the control group (P<0.05). Compared before treatment, the dorsal hand skin thickness and middle finger skin thickness on the affected side were decreased in both groups after 4 weeks of treatment (P<0.05). Compared with the control group, the observation group showed thinner dorsal hand and middle finger skin thickness after 4 weeks of treatment (P<0.05).
Conclusion:
EA at neuro-arterial stimulation points effectively alleviates pain and edema in patients with post-stroke SHS, and demonstrates superior efficacy compared to topical western medication.

Hypothesizing the Oleic Acid-Mediated Enhanced and Sustained Transdermal Codelivery of Pregabalin and Diclofenac Adhesive Nanogel: A Proof of Concept
Article
作者: Singh, Snigdha ; Noor, Afeefa ; Kohli, Kanchan ; Datta, Deepanjan ; Rathee, Anjali
::
Pregabalin (PG) and diclofenac diethylamine (DEE) are anti-inflammatory
molecules that are effective in relieving inflammation and pain associated with
musculoskeletal disorders, arthritis, and post-traumatic pain, among others.
Intravenous and oral delivery of these two molecules has their limitations. However,
the transdermal route is believed to be an alternate viable option for the delivery of
therapeutic molecules with desired physicochemical properties. To this end, it is vital to
understand the physicochemical properties of these drugs, dosage, and strategies to
enhance permeation, thereby surmounting the associated constraints and concurrently
attaining a sustained release of these therapeutic molecules when administered in
combination. The present work hypothesizes the enhanced permeation and sustained
release of pregabalin and diclofenac diethylamine across the skin, entrapped in the
adhesive nano-organogel formulation, including permeation enhancers. The solubility
studies of pregabalin and diclofenac diethylamine in combination were performed in
different permeation enhancers. Oleic acid was optimized as the best permeation
enhancer based on in vitro studies. Pluronic organogel containing pregabalin and
diclofenac diethylamine with oleic acid was fabricated. Duro-Tak® (87-2196) was
added to the organogel formulation as a pressure-sensitive adhesive to sustain the
release profile of these two therapeutic molecules. The adhesive organogel was
characterized for particle size, scanning electron microscopy, and contact angle
measurement. The HPLC method developed for the quantification of the dual drug
showed a retention time of 3.84 minutes and 9.69 minutes for pregabalin and
diclofenac, respectively. The fabricated nanogel adhesive formulation showed the
desired results with particle size and contact angle of 282 ± 57 nm and ≥120⁰,
respectively. In vitro studies showed the percentage cumulative release of 24.90 ±
4.65% and 33.29 ± 4.81% for pregabalin and diclofenac, respectively. In order to
accomplish transdermal permeation, the suggested hypothesis of fabricating PG and
DEE nano-organogel in combination with permeation enhancers will be a viable drug
delivery method. In comparison to a traditional gel formulation, oleic acid as a
permeation enhancer increased the penetration of both PG and DEE from the
organogel formulation. Notably, the studies showed that the use of pressure-sensitive
adhesives enabled the sustained release of both PG and DEE.Therefore, the results
anticipated the hypothesis that the transdermal delivery of adhesive PG and DEEbased
nanogel across the human skin can be achieved to inhibit inflammation and
pain.
