A new, valid method was developed for quantitative spectrofluorimetric analysis of dapagliflozin (DGF) in its pure form and its commercially available tablets (Farxiga®). The proposed analytical method based on measurement of fluorescence intensity for DGF at 303 nm after excitation at 278 nm. Various experimental parameters influencing the fluorescence of DGF were examined to produce the optimal conditions. DGF was successively assayed in concentration range of (100-1000 ng mL) with lower detection limit (LOD) of 26.49 and quantitation limit (LOQ) was 79.48 ng mL. The suggested method was validated according to ICH guidelines for the estimation of DGF in its pure form and its new dosage form with percent recovery of 100.43 ± 1.15. The proposed method was adapted to examine DGF in content uniformity testing according to United States Pharmacopeia guidelines. This method can be used in routine analysis of DGF in quality control lab.

The environmental impact of chemicals used in aquaculture, particularly nitrofurantoin, has raised global concern. Nitrofurantoin, a broad-spectrum antimicrobial, is commonly used in aquaculture despite safety risks. Determination of nitrofurantoin in water samples of fish ponds is necessary to ensure the safety and quality of seafood.

Background/objectives: Selective laser sintering (SLS) is one of the most promising 3D printing techniques for pharmaceutical applications as it offers numerous advantages, such as suitability to work with already approved pharmaceutical excipients, the elimination of solvents, and the ability to produce fast-dissolving, porous dosage forms with high drug loading. When the powder mixture is exposed to elevated temperatures during SLS printing, the active ingredients can be converted from the crystalline to the amorphous state, which can be used as a strategy to improve the dissolution rate and bioavailability of poorly soluble drugs. This study investigates the potential application of SLS 3D printing for the fabrication of tablets containing the poorly soluble drug carvedilol with the aim of improving the dissolution rate of the drug by forming an amorphous form through the printing process.

Manganese-based alloys with the composition MnFeZ (Z = Si, Al) have been extensively investigated in recent years due to their potential applications in spintronics. The MnFeSi alloy, prepared in the form of ingots, powders, or ribbons, exhibits either a cubic full-Heusler (2) structure, an inverse-Heusler (XA) structure, or a combination of both. In contrast, the MnFeAl alloy has so far been synthesized only in the form of ingots, featuring a primitive cubic (β-Mn type) structure.
