A multivariate ANN-CCD integrative model using cellulose based polymers for the development of osmotically controlled push-pull dexibuprofen tablets and its predictive pharmacokinetic modeling. (PubMed, Eur J Pharm Sci) - "Physiologically Based Pharmacokinetic (PBPK) models for optimized formulations were developed using GastroPlusTM to simulate in vivo plasma profiles and compare with the real-time human pharmacokinetic data. The study demonstrates the promising role of biocompatible macromolecules in compressing the poorly compressible molecule, dexibuprofen, and modulating its release and in vivo pharmacokinetic performance from an osmotically controlled push-pull system for 12 h."

Analyzing Spatial Variations in Molecular Mobility in Hydrated Amorphous Drug-Polymer Blends Using Fourier Transform Fluorescence Recovery After Photobleaching and Image Segmentation. (PubMed, J Phys Chem B) - "Stokes-Einstein estimates translated these values into local viscosities spanning ∼0.41 Pa·s (gel), 4.5 Pa·s (ibuprofen-rich), and 22 Pa·s (low-hydration ASD), highlighting pronounced microheterogeneity within the hydrated ASD matrix. Together, these results provide a quantitative, spatially explicit link between drug loading, phase morphology, local mobility, and macroscopic release, and establish segmented FT-FRAP as a practical tool for diagnosing failure mechanisms and guiding formulation of high-loading ASDs."

Network pharmacology identifies repurposable drugs targeting host pathways across the oral-gut-lung axis. (PubMed, Naunyn Schmiedebergs Arch Pharmacol) - "Centrality-weighted drug prioritization consistently ranked indomethacin, ibuprofen, dexibuprofen, mesalazine, and cannabidiol as high-confidence repositioning candidates for densely connected host networks. Enrichment analyses demonstrated convergence on immune signaling pathways, cytoskeletal remodeling, PPAR signaling, and focal adhesion networks. This study presents a reproducible and generalizable network medicine workflow that formalizes interactome construction, multi-metric centrality assessment, and composite drug ranking in a unified analytical framework. The proposed strategy enables the systematic identification of conserved host regulatory vulnerabilities and repositionable therapeutics across infectious and chronic inflammatory diseases, thereby advancing host-directed therapeutic discovery in translational biomedical informatics."

Pharmacokinetics, dosing exposure and safety of oral ibuprofen in Chinese preterm neonates with patent ductus arteriosus: preliminary report. (PubMed, BMJ Paediatr Open) - P=N/A | "The recommended dosage regimen for Chinese preterm neonates with hsPDA may be insufficient to achieve targeted therapeutic exposure. Importantly, our study indicated that even at a relatively high dose, drug exposure might remain within the therapeutic window. Moreover, we observed a higher conversion ratio of R-IBU to S-IBU in these neonates than in adults. The use of ibuprofen may be associated with an elevated risk of jaundice in preterm infants."

Simultaneous rapid structure identification and accurate quantitation of chiral drugs based on a home-built polarized Raman microscope. (PubMed, Opt Lett) - "The experimental results of the coefficients of determination (R2) are 0.957 for racemic ibuprofen and 0.988 for (S)-ibuprofen, and their root mean square error of prediction (RMSEP) values are 0.126% and 0.049%, respectively. These preliminary results give a hint that polarized Raman spectroscopy (PRS) is a powerful non-destructive analytical tool for drug applications.

Impact of Drug Hydrophilicity on Transdermal Delivery by Nanoemulsions. (PubMed, Pharmaceutics) - "Viscosity values covered broad ranges (3-9532 mPa·s for salbutamol; 13.4-9759 mPa·s for ibuprofen), with salbutamol generating an extended high-viscosity domain at 50% (w/w) surfactant and ibuprofen showing a narrower viscosity maximum at 30-40% surfactant...High surfactant levels suppressed permeation for both APIs, but the dominant positive drivers differed: balanced oil-water ratios for salbutamol and hydration-dependent diffusional resistance for ibuprofen. These findings demonstrate that API polarity and interfacial portioning behavior decisively govern NE performance, providing a framework for rational tailoring of oil-surfactant-water ratios to maximize transdermal delivery efficiency."

Double Salts and Racemate in Mefloquine-Ibuprofen and Mefloquine-Ketoprofen Systems. A Structural and Thermochemical Analysis. (PubMed, Chirality) - "Using a drug-drug approach, we have investigated the crystallization behavior of Mefloquine (Mf), a racemic antimalarial drug, in combination with enantiopure (S)-ibuprofen and (S)-ketoprofen, as well as their racemic forms. On the other hand, the racemate with ketoprofen and the double salt with ibuprofen are the most soluble structures, suggesting that they are more stable systems than their counterparts. These findings support the view that double salt formation in such systems results from structural mimicry of racemates, emphasizing the challenges of predictable enantiomeric resolution and the importance of understanding structure-property relationships in chiral crystallization."

The Stereoselective Pharmacokinetics of Ibuprofen Enantiomers in Mice, Guinea Pigs, and Rats. (PubMed, Chirality) - "A chiral LC-MS/MS method was employed to simultaneously determine (R)-(-)-ibuprofen and (S)-(+)-ibuprofen in trace whole blood samples (5 μL)...Conversion rates calculated from R-IBU and S-IBU concentrations following racemic IBU administration exhibited significant interspecies differences: 54.9 ± 5.6% (rats), 76.6 ± 5.3% (mice), and 65.6 ± 6.7% (guinea pigs). In contrast, no significant species differences were observed when conversion rates were derived from S-IBU concentrations after administration of individual enantiomers (R-IBU and S-IBU), yielding values of 65.9 ± 6.5%, 76.8 ± 21.2%, and 66.3 ± 14.4% for rats, mice, and guinea pigs, respectively."

Theoretical Examination on the Chiral Separation Mechanism of Ibuprofen on Cellulose Tris(4-methylbenzoate). (PubMed, Molecules) - "Our results demonstrated that, based on the optimized geometry using the ML-T2C-ELG method, the complexation energy of S-ibuprofen with CMB obtained at B3LYP-D3(BJ)/6-311G(d) level is more negative than that of R-ibuprofen, which is caused by the greater hydrogen bonding and π-π stacking interactions between CMB and S-ibuprofen...Moreover, the ML-T2C-ELG method was found to be valuable for optimizing the geometries of such flexible and large systems, which allows for a more accurate description of interactions between soft polymers and small molecules when coupled with the docking simulation. It is anticipated that this study can provide beneficial insights for future optical resolution mechanisms of other chiral drugs."
