However, the adverse effects of non-biodegradable intravitreal implants of fluocinolone acetonide (FA), such as postoperative hypotony and secondary injury during removal of the implant matrix, are frequent occurrence to affect patient's compliance. Herein, biodegradable poly (lactic-co-glycolic acid) (PLGA)-based microspheres (MS) containing fluocinolone acetonide (FA@MS) were prepared using an optimized electrospray technology with a voltage of 10.07 kV and the receiving distance of 9.87 cm. The obtained FA@MS with the average particle size of 2.25 μm possessed the high encapsulation efficiency (94.85%) and drug content (9.48%). In vitro release demonstrated that FA@MS exhibited sustained release for 30 days, and the release characteristic of FA@MS conformed to the Weibull model. In vivo study in a rabbit NIU model indicated that FA@MS continuously released the drug for at least 28 days in vitreum and progressively decreased inflammation of NIU. Furthermore, the intraocular pressure of rabbits treated with blank MS and FA@MS remained the normal level for 28 days, which demonstrated the favorable biosafety of FA@MS.

Pharmacokinetic results showed that the accumulation of QUE in plasma of the NPC-QUE-L group was 1.28 times and 2.43 times that of the QUE Solution and QUE-L groups, respectively. The release amount of NPC-QUE-L in an acidic environment was significantly higher than in physiological pH value. The order of the tumor cell inhibition rate in different pH environments was NPC-QUE-L > PC-QUE-L > QUE-L. In addition, the cellular uptake of NPC-modified liposomes was higher than that of PC-modified and unmodified liposomes, indicating that NPC had good pH-sensitivity and targeting. In the triple-negative breast cancer (TNBC) model, the relative tumor proliferation rate of NPC-QUE-L is about 73%, which is better than that of the QUE solution group.

Recently, cinacalcet HCl has been probed for repurposing as antibacterial agent.

Solid dispersion formulations using Poloxamer 407, with and without Soluplus®, were prepared via solvent evaporation and hot melt congealing methods. The resulting formulations were analyzed using differential scanning calorimetry, FTIR spectroscopy, X-ray powder diffraction, and dissolution studies. These formulations significantly enhanced cinacalcet HCl dissolution compared to the unprocessed form, achieving up to a 15-fold increase in Q5 (percent of cinacalcet HCl dissolved after 5 min). The dissolution efficiency rose from 28% for the pure drug to 94.8 and 87.8% for formulations F6 and F7, respectively. Microbiological evaluations confirmed the antibacterial effect of cinacalcet HCl, which was notably increased in the Poloxamer 407 and Soluplus® hybrid formulation (F7) with a MIC of 64-128 µg/ml.

The choice of polymers and their rheological properties is crucial for successful extrusion-based printing. While 3D printing accelerates drug development, challenges remain regarding quality control. Quality-by-design (QbD) approaches are essential to ensure safe and effective pharmaceutical products. This study highlights the role of critical process parameters (CPPs), such as infill density and printing speed, in producing poly(lactic acid)-based intravaginal rings. The effects of CPPs on critical quality attributes (CQAs), such as ring dimensions, weight, and swelling degree, were examined. Printing speed (25-100 mm/s) and infill density (0-20%) significantly affected weight and dimensions, with average weights ranging from 0.537 g to 0.629 g. Internal dimensions varied between 9.73 mm and 9.81 mm, while external dimensions ranged from 19.43 mm to 19.69 mm.
